[PMID: 37957032 DOI: 10.1111/1471-0528.17697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 09/21/2023] [Accepted: 10/15/2023] [Indexed: 11/15/2023]
Abstract
BACKGROUND There is no consensus on tests required to either diagnose unexplained infertility or use for research inclusion criteria. This leads to heterogeneity and bias affecting meta-analysis and best practice advice. OBJECTIVES This systematic review analyses the variability of inclusion criteria applied to couples with unexplained infertility. We propose standardised criteria for use both in future research studies and clinical diagnosis. SEARCH STRATEGY CINAHL and MEDLINE online databases were searched up to November 2022 for all published studies recruiting couples with unexplained infertility, available in full text in the English language. DATA COLLECTION AND ANALYSIS Data were collected in an Excel spreadsheet. Results were analysed per category and methodology or reference range. MAIN RESULTS Of 375 relevant studies, only 258 defined their inclusion criteria. The most commonly applied inclusion criteria were semen analysis, tubal patency and assessment of ovulation in 220 (85%), 232 (90%), 205 (79.5%) respectively. Only 87/220 (39.5%) studies reporting semen analysis used the World Health Organization (WHO) limits. Tubal patency was accepted if bilateral in 145/232 (62.5%) and if unilateral in 24/232 (10.3%). Ovulation was assessed using mid-luteal serum progesterone in 115/205 (56.1%) and by a history of regular cycles in 87/205 (42.4%). Other criteria, including uterine cavity assessment and hormone profile, were applied in less than 50% of included studies. CONCLUSIONS This review highlights the heterogeneity among studied populations with unexplained infertility. Development and application of internationally accepted criteria will improve the quality of research and future clinical care.

Reprod Biomed Online 2023; 46:566-576. [PMID: 36456392 DOI: 10.1016/j.rbmo.2022.11.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 09/28/2022] [Accepted: 11/03/2022] [Indexed: 11/09/2022]
Abstract
RESEARCH QUESTION What is the optimal lead follicle size in letrozole, human menopausal gonadotrophin and intrauterine insemination (IUI) cycles with and without spontaneous LH surges? DESIGN This retrospective cohort study included 3797 letrozole HMG IUI cycles between January 2010 and May 2021. All cycles were divided into two groups: the HCG trigger group (trigger day LH ≤15 mIU/ml) and the spontaneous LH surge group (trigger day LH >15 mIU/ml). These two groups were subdivided into smaller groups based on the diameter of the follicles. The primary outcome measure was clinical pregnancy rate. Logistic regression analysis was conducted to explore other risk factors. RESULTS In the HCG trigger group, the clinical pregnancy rate varied significantly, with rates of 20.8%, 14.9% and 11.8% for the 16.1-18.0, 18.1-20.0 and 20.1-22.0 mm groups, respectively (P = 0.005). In the spontaneous LH surge group, the pregnancy rate of follicles within 14.1-16.0 mm was significantly higher than that of follicles within 20.1-22.0 mm (adjusted OR 0.533, 95% CI 0.308 to 0.923, P = 0.025). Also, patients with two lead follicles were 2.569 times more likely to achieve a clinical pregnancy than those with only one lead follicle (adjusted OR 2.569, 95% CI 1.258 to 5.246, P = 0.010). The duration of infertility was also found to be a common influencing factor in both groups. CONCLUSIONS The optimal lead follicle size was between 16.1 and 18.0 mm in HCG-triggered letrozole HMG IUI cycles. If the lead follicle size is relatively small (14.1-18.0 mm) when a spontaneous LH surge occurs, there is no need to cancel the IUI cycle.

Abstract
Purpose To develop a predictive score for the success of intrauterine insemination (IUI) based on clinical parameters. Methods We performed a retrospective cohort study evaluating the homologous IUI cycles performed at a single university-based reproductive medical center between 2009 and 2017. The primary outcome measure was pregnancy, defined as positive serum human chorionic gonadotropin (hCG) 12–14 days after IUI. Predictive factors for pregnancy after IUI were identified, and a predictive score was developed using a multivariable continuation ratio model. Results Overall, 1437 IUI cycles in 758 couples were evaluated. We found a per cycle pregnancy rate of 10.9% and a cumulative pregnancy rate of 19.4%. In a multivariable analysis, the probability of pregnancy was negatively associated with female age ≥ 35 years (OR 0.63, 95% CI 0.41–0.97, p = 0.034), endometriosis, unilateral tubal factor, or anatomical alteration (OR 0.54, 95% CI 0.33–0.89, p = 0.016), anti-Mullerian hormone (AMH) < 1 ng/ml (OR 0.50, 95% CI 0.29–0.87, p = 0.014), and total progressive motile sperm count (TPMSC) < 5 mil (OR 0.47, 95% CI 0.19–0.72, p = 0.004). We developed a predictive clinical score ranging from 0 to 5. Following 3 cycles, couples in our cohort with a score of 5 had a cumulative probability of achieving pregnancy of nearly 45%. In contrast, couples with a score of 0 had a cumulative probability of only 5%. Conclusion IUI success rates vary widely depending on couples’ characteristics. A simple to use score could be used to estimate a couple’s chance of achieving pregnancy via IUI, facilitating individualized counseling and decision-making.

J Assist Reprod Genet 2022; 39:1445-1491. [PMID: 35731321 PMCID: PMC9365895 DOI: 10.1007/s10815-022-02551-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2022] [Accepted: 06/15/2022] [Indexed: 10/17/2022] Open
Abstract
PURPOSE The objective of this review is to define live birth rate (LBR) and clinical pregnancy rate (CPR) for women ≥ 40 undergoing ovulation induction (OI)/intrauterine insemination (IUI). METHODS A systematic review was performed in accordance with PRISMA guidelines using PubMed and Google Scholar. The primary and secondary outcomes of interest were LBR and CPR, respectively. RESULTS There were 636 studies screened of which 42 were included. In 8 studies which provided LBR for partner sperm, LBR/cycle ranged from 0 to 8.5% with majority being ≤ 4%. Cumulative LBR was 3.6 to 7.1% over 6 cycles with the majority of pregnancies in the first 4. In the four studies providing LBR for donor sperm cycles, LBR/cycle ranged from 3 to 7% with cumulative LBR of 12 to 24% over 6 cycles. The majority of pregnancies occurred in the first 6 cycles. There were three studies with LBR or CPR/cycle ≥ 1% for women ≥ 43. No studies provided data above this range for women ≥ 45. In 4 studies which compared OI/IUI and IVF, the LBR from IVF was 9.2 to 22% per cycle. In 7 studies which compared outcomes by stimulation protocol, no significant differences were seen. CONCLUSION For women ≥ 40 using homologous sperm, the highest probability of live birth is via IVF. However, if IVF is not an option, OI/IUI may be considered for up to 4 cycles in those using partner sperm or 6 cycles with donor sperm. For women > 45, OI/IUI is likely futile but a limited trial may be considered for psychological benefit while encouraging consideration of donor oocyte IVF or adoption. Use of gonadotropins does not appear to be more effective than oral agents in this age group.

Abstract
OBJECTIVE Unexplained infertility is defined by the absence of identifiable causes of infertility. The results of randomized studies and meta-analysis regarding the treatment of unexplained infertility are discordant due to methodological problems. DESIGN The aim of this study is to compare the clinical pregnancy rate per cycle (CPR/c) in IUI and IVF/ICSI in cases of unexplained infertility, according to the woman's age group and to identify the factors which predict success. INTERVENTIONS We performed a retrospective study in two ART centers, comparing overall clinical pregnancy, ongoing pregnancy and live birth rates in IVF/ICSI and IUI. We also compared pregnancy and birth rates according to different female age groups. RESULTS 855 IVF/ICSI and 804 IUI cycles were compared. We found a significant difference (p < 0.001) in the pregnancy and live birth rates per cycle between IUI and IVF/ICSI, overall and in the different female age groups, except in women aged 40 and over. The greatest chances of pregnancy with IUI are found in women with secondary unexplained infertility, during the first two cycles and with a bi-follicular response to stimulation. In IVF/ICSI, pregnancy rates are higher in women with secondary unexplained infertility, in the first two cycles, in IVF and in women receiving a transfer of two embryos regardless of the embryonic stage. CONCLUSION We recommend IVF/ICSI treatment rather than IUI for unexplained infertility (OR CPR/c 4.20 with 95% CI [3.72-4.68]). This is in accordance with NICE, which advises the use of IVF after 2 years.

Front Endocrinol (Lausanne) 2022; 13:880538. [PMID: 35600574 PMCID: PMC9114301 DOI: 10.3389/fendo.2022.880538] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2022] [Accepted: 04/01/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND To date, no consensus has been reached on whether to wait for spontaneous luteinizing hormone (LH) surge to occur or to trigger ovulation regardless of the presence of an LH surge for achieving higher success rate in intrauterine insemination (IUI) cycles. Therefore, we hope to investigate the effect of the presence of a spontaneous LH surge on pregnancy outcomes in letrozole-human menopausal gonadotropin (LE-HMG) IUI cycles. METHODS In this retrospective cohort study, a total of 6,285 LE-HMG IUI cycles were included between January 2010 and May 2021. Cycles were categorized into three groups: the trigger + LH surge group, the trigger only group, and the LH surge only group. The primary outcome measure was the clinical pregnancy rate. A logistic regression analysis was performed to explore other risk factors affecting the clinical pregnancy rate. RESULTS No significant differences were observed in biochemical pregnancy rate (P =0.640), clinical pregnancy rate (P =0.702), ongoing pregnancy rate (P =0.842), and live birth rate (P =0.951) among the three groups. The binary logistic regression analysis also confirmed that the existence of an LH surge was not associated with clinical pregnancy. There was a difference in ectopic pregnancy rates (P =0.045), but logistic regression showed that the presence of a spontaneous LH surge has no association with ectopic pregnancy. Nonetheless, patients with lead follicles within 18.1-20.0 mm/20.1-22.0 mm and a long duration of LE treatment were less likely to get ectopic pregnant compared with patients with 14.1-16.0 mm lead follicles and shorter LE treatment (OR: 0.142, 95% CI: 0.023-0.891, P =0.037; OR: 0.142, 95% CI: 0.022-0.903, P =0.039; OR: 0.445, 95% CI: 0.235-0.840, P = 0.013). CONCLUSIONS The presence of a spontaneous LH surge in triggered LE-HMG IUI cycles does not appear to improve pregnancy rates. Thus, we suggest that waiting for an LH surge to occur is not necessary in triggered LE-HMG IUI cycles.

Abstract
OBJECTIVE To compare the success of ovulation induction using oral agents versus gonadotropins (GTs) in women ≥38 years old. STUDY DESIGN A retrospective cohort study was performed including all first to third stimulated IUI cycles conducted after the age of 38 years in a single academic fertility center between 01/2011 and 03/2018. RESULTS A total of 1596 IUI cycles were included. 240 cycles were with clomiphene citrate (CC), 176 letrozole cycles and 1180 gonadotropin (GTs) cycles. The GTs group were older (p < 0.001), had lower antral follicular count (p < 0.001), and thicker endometrium (p < 0.001) compared to the oral agent groups. The letrozole group had a less mature follicles (p = 0.004) at the time of triggering compared to the other groups. No difference in pregnancy or clinical pregnancy rates was observed after controlling for confounders when comparing the 3-groups. 5 multiple pregnancies occurred, all in the GTs group. The groups were subdivided by age; 38-39 years old (N = 750) and 40-43 years old (N = 846). Nevertheless, no statistical difference was observed in pregnancy rates and clinical pregnancy rates between oral agents and GTs when controlling for the confounding effects among women at age 38-39 (p = 0.47, p = 1.0; respectively) and among women 40-43-years-old (p = 0.16, p = 1.0; respectively). CONCLUSIONS Clearly costs of oral agents are lower and they are more patient friendly than GTs, therefore oral agents should be first line for ovarian stimulation and IUI in women 38-43-years of age.

Abstract
Objective: To evaluate the effect of human chorionic gonadotropin (hCG) trigger ovulation on pregnancy outcomes in natural IUI cycles with donor sperm. Methods: This retrospective cohort study included 5,610 first-natural IUI cycles with donor sperm in infertile couples during the period from January 2012 to December 2017. To control for other confounding factors, our analysis was restricted to normo-ovulatory women without tubal infertility. The main outcome measure was live birth rate; the secondary outcomes included rates of clinical pregnancy and miscarriage. Results: In the crude analysis, both the clinical pregnancy (27.40 vs. 22.73%; P = 0.001) and live birth rates (24.52 vs. 20.13%; P = 0.007) were significantly higher for the hCG group than for the spontaneous LH group. After adjustment for a number of confounding factors, the reproductive outcomes were still significantly worse for the spontaneous ovulatory group. Conclusions: Among women undergoing natural cycle IUI with donor sperm, hCG triggered ovulation for timing insemination offers beneficial impacts on both clinical pregnancy rates and live birth rates.

Abstract
OBJECTIVES The objective of our study is to evaluate the impact of luteal phase support by hCG in intrauterine inseminations preceded by ovarian gonadotropin stimulation. METHODS A retrospective study was conducted at the CHU of Nice between March 1, 2016 and October 31, 2017. During this period, 300 intrauterine inseminations were included in data analysis. Ovarian stimulation was performed by gonadotropins and a GnRH antagonist was added, if needed. Following a modification of standard operative procedure in the department, patients who performed an intrauterine insemination from December 1, 2016 received luteal phase support with two injections of hCG 1500 IU, performed at three days of interval. Pregnancy and ovarian hyperstimulation syndrome were the primary and secondary study endpoints, respectively. RESULTS Out of 300 inseminations included in the analysis, 144 were performed with luteal phase support and 156 without support. No statistically significant difference in pregnancy rate was observed between these two groups (19.4% of pregnancy in the luteal phase support group and 15.38% in the group without luteal phase support, P=0.353). No ovarian hyperstimulation syndrome occurred over the course of the study. CONCLUSION Our study shows a slight improvement of pregnancy rate in the group subjected to luteal phase support by hCG after intrauterine insemination, but the benefit was not significant. A randomised prospective study based on a large cohort could help to assess the effect of luteal phase support during intrauterine inseminations.

Abstract
BACKGROUND There are many variables that may influence the success rates of intrauterine insemination (IUI) treatment. Therefore, a regular audit program is needed for planning effective infertility treatment and improving pregnancy outcomes. AIMS AND OBJECTIVES The main objective of this study was to identify the crucial predicting factors that can influence the IUI success. MATERIALS AND METHODS A retrospective analysis of 800 IUI cycles done from January, 2013 to August, 2017 in 651 couples with various etiologies of infertility. The common etiologies included female factor of ovulatory dysfunction, tubal, endocrinal, male factor, male and female factors combined, and unexplained factors. Ovulation induction was done either by clomiphene citrate (CC) alone or in combination of CC with gonadotropins or pure gonadotropins only. Human chorionic gonadotropin trigger was given when at least one dominant follicle measuring ≥18 mm with an endometrial thickness of >7 mm was obtained. IUI was done post 36 h of trigger. The double-density gradient method was the preferred method of sperm preparation. RESULTS In 800 cycles in corresponding 651 couples, the total outcome was 113 pregnancies (14.1%) per cycle with overall pregnancy rate (PR) per couple of 17.3%. The highest PR was observed in the patient with ovulatory dysfunction (21.2%), followed by patients with combined factor (15.1%) and male factor (14.7%). In the study, a higher PR was achieved in the female ≤25 years (18.9%) P < 0.04 with significant findings with duration of infertility ≤5 years (15.1%) having primary infertility (14.5%) with low body mass index <25 (14.1%). IUI success rate was highest in the first cycle (14.6%) followed by second cycle (14.0%) and third cycle (3.5%). CONCLUSION IUI audit enables the characterization of prognostic factors to achieve improved PR. This study identifies the factors that can predict improved pregnancy outcome in women age ≤25 years and endometrium thickness between 9 and 11 mm. We also recommend IUI as a first line of infertility treatment for couples in low-income setting provided the women age and duration of infertility are acceptably low.

Abstract
INTRODUCTION Using the structured methodology of French guidelines (HAS-CNGOF), the aim of this chapter was to formulate good practice points (GPP), in relation to optimal non-ART management of endometriosis related to infertility, based on the best available evidence in the literature. MATERIALS AND METHODS This guideline was produced by a group of experts in the field including a thorough systematic search of the literature (from January 1980 to March 2017). Were included only women with endometriosis related to infertility. For each recommendation, a grade (A-D, where A is the highest quality) was assigned based on the strength of the supporting evidence. RESULTS Management of endometriosis related to infertility should be multidisciplinary and take account into the pain, the global evaluation of infertile couple and the different phenotypes of endometriotic lesions (good practice point). Hormonal treatment for suppression of ovarian function should not prescribe to improve fertility (grade A). After laproscopy for endometriosis related to infertility, the Endometriosis Fertility Index should be used to counsel patients regarding duration of conventional treatments before undergoing ART (grade C). After laparoscopy surgery for infertile women with AFS/ASRM stage I/II endometriosis or superficial peritoneal endometriosis, controlled ovarian stimulation with or without intrauterine insemination could be used to enhance non-ART pregnancy rate (grade C). Gonadotrophins should be the first line therapy for the stimulation (grade B). The number of cycles before referring ART should not exceed up to 6 cycles (good practice point). No recommendation can be performed for non-ART management of deep infiltrating endometriosis or endometrioma, as suitable evidence is lacking. DISCUSSION AND CONCLUSION Non-ART management is a possible option for the management of endometriosis related to infertility. Endometriosis Fertilty Index could be a useful tool for subsequent postoperative fertility management. Controlled ovarian stimulation can be proposed.

Abstract
Objective To evaluate the IUI success factors relative to controlled ovarian stimulation (COS) and infertility type, this retrospective cohort study included 1251 couples undergoing homologous IUI. Results We achieved 13% clinical pregnancies and 11% live births. COS and infertility type do not have significant effect on IUI clinical outcomes with unstable intervention of various couples' parameters, including the female age, the IUI attempt rank, and the sperm quality. Conclusion Further, the COS used seemed a weak predictor for IUI success; therefore, the indications need more discussion, especially in unexplained infertility cases involving various factors. Indeed, the fourth IUI attempt, the female age over 40 years, and the total motile sperm count <5 × 106 were critical in decreasing the positive clinical outcomes of IUI. Those parameter cut-offs necessitate a larger analysis to give infertile couples more chances through IUI before carrying out other ART techniques.

Abstract
INTRODUCTION Understanding and improving IUI pregnancy rates has enormous global appeal and application. This pilot study goes one step further by utilising consecutive ejaculates from men with oligozoospermia and comparing with normozoospermic male group. MATERIALS AND METHODS A retrospective analysis was performed on 117 IUI-stimulated treatment cycles in a small fertility clinic in North Middlesex University Hospitals Trust, UK, within a NHS setting. Risks of OHSS and multiple births are carefully controlled. RESULTS In our cohort, several factors are associated with positive IUI pregnancies and these were: age of the woman, inseminating with ≥5 total progressive motile sperm; having ≥50 % Grade A sperm progression and having ≥1 follicle achieved with a realistic hMG dosage, hCG trigger and IUI of 29.7 h (2.5-38.4 h), with an endometrial thickness of 10.7 mm (6.6-13.4 mm). Bifollicular presence in at least half the cases along with hMG protocols added usefully to the pregnancy outcomes. CONCLUSIONS The pregnancy rates per cycle were 19 and 23 % in the consecutive ejaculates and non-consecutive ejaculate groups, respectively, P = 0.59. For the whole cohort, the pregnancy rate was 20.51 % per cycle and 33.8 % per women. This approach if validated with large RCT will have universally beneficial effects.

Predicting suitable timing for artificial reproductive technology treatment in aged infertile women. Reprod Med Biol 2016; 15:253-259.

Abstract
It has been widely accepted that the age of women plays a fundamental role in fecundity, and age-related fertility decline has one of the most significant and detrimental effects on the success rate of infertility treatment. Therefore, treatment cycles of non-in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) treatment for infertile women of advanced aged have been limited due to their lack of efficacy, and they are often optimized, compared to IVF/ICSI treatment. Recent trends in infertility treatment apparently indicate that IVF/ICSI treatment, including egg donation, is frequently offered to aged women for first-line management, despite its heavy burden, but hasty IVF/ICSI treatment should be avoided, considering its socioeconomic problems. It is important to distinguish women who could conceive by non-IVF/ICSI treatment, although the optimization of non-IVF/ICSI treatment protocols remains poorly understood. This review focuses on extracting aged patients who have higher chance of conceiving with non-IVF/ICSI treatment and providing necessary and sufficient infertility treatment. After initial evaluation for fertility, including tubal factor, male factor, the presence of endometriosis and/or adenomyosis, and ovarian reserve, the outcomes of fertility treatment can be predicted to some extent in aged infertile women.

Abstract
Objective: To exam semen parameters in predicting intrauterine insemination (IUI) outcomes in couples with male factor. Study design: This retrospective study was performed at department of infertility and sexual medicine from September 2007 to February 2014. 307 couples with male factor infertility were included and 672 IUI cycles were analyzed. Results: From 672 inseminations performed on 307 couples, there are 27.36% couples get pregnancy (84 out of 307) and the overall pregnancy rate was 12.95% (87 out of 672) of IUI. With the increase of post total progressive sperm count, the clinical pregnancy rate increased. When the initial progressive sperm count was lower than 5*106, there was no pregnant in the IUI cycle. At the end of the third cycle, 85 clinical pregnancies had been achieved (97.70%). Conclusions: The initial total progressive sperm count lower than 5*106 means the poor outcome of IUI in the infertile couples with male factor. If the infertile couples with male factor don’t get pregnancy after three IUI cycles, the couples should receive re-assessment or other artificial reproductive technology.

A "four-cycle program" improves the estimate of the cumulative pregnancy rate and increases the number of actual pregnancies in IUI treatment: a cohort study. Eur J Obstet Gynecol Reprod Biol 2014; 176:173-7. [PMID: 24656656 DOI: 10.1016/j.ejogrb.2014.02.028] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2013] [Revised: 02/11/2014] [Accepted: 02/16/2014] [Indexed: 11/23/2022]
Abstract
OBJECTIVE To demonstrate that reduction of the cumulative dropout rate (CDR) improves the accuracy of the estimate of the cumulative pregnancy rate (CPR) in a set of four intrauterine insemination (IUI) cycles ("four-cycle program") and increases the total number of pregnancies obtained. STUDY DESIGN Single-centre retrospective observational cohort study of couples who underwent IUI cycles at the Andros Day Surgery Clinic, Palermo, from 1997 to 2011. The main outcome measure was the calculation of the CPR, with life table analysis, firstly by giving the same probability of pregnancy to the dropouts as the patients who continued the treatment (usual method) and secondly by considering this probability null (conservative method). The difference between these two methods was used to verify the accuracy of the estimate. RESULT(S) In the 15 years, 924 couples underwent 2956 cycles carried out consecutively in a set of four cycles. The CDR was 16%. The CPR was 31.4% with the usual method and 29.1% with the conservative method. The difference between the two estimates was not significant, indicating a high reliability of the results and a good accuracy of the calculation. Furthermore, maintenance of a low CDR permits improvement of the CPR, as was demonstrated by considering scenarios with worse dropout rates. CONCLUSION(S) The "four-cycle program" results in a reduction in the CDR, allowing a better estimation of the CPR, and increases the number of actual pregnancies in IUI. The CPR should become the focus for reporting outcome rates in IUI cycles. Reduction of the dropout rate allows us to give the patient a more reliable and accurate estimate of the pregnancy rate.

Abstract
OBJECTIVE To identify the prognostic factors for pregnancy after intrauterine insemination with the husband's sperm (IUI-H). DESIGN Retrospective study. SETTING A single university medical center. PATIENT(S) 851 couples, for 2,019 IUI-H cycles. INTERVENTION(S) After controlled ovarian stimulation, IUI-H performed 36 hours after ovulation triggering or 24 hours after a spontaneous luteinizing hormone (LH) surge. MAIN OUTCOME MEASURE(S) Clinical pregnancy rate per cycle (PR) and delivery rate per cycle (DR). RESULT(S) The overall PR was 14.8% and DR 10.8%. Higher PR and DR were observed for patients presenting with ovulation disorders (particularly polycystic ovary syndrome) or with male infertility. Secondary infertility in the woman appeared to be a positive prognostic factor as did a basal follicle-stimulating hormone (FSH) level ≤ 7 IU/L and ovulation triggering over spontaneous LH rise. The other parameters influencing the results were the women's age, the number of mature follicles obtained (≥ 2), the endometrial thickness (10-11 mm), and the number of progressive motile spermatozoa inseminated (>1 million). CONCLUSION(S) In women aged ≤ 38 years, IUI-H should be considered as an option, particularly in cases of female infertility from ovulation disorders, in cases of a normal ovarian reserve, in cases of secondary infertility, or when ≥ 1 million progressive sperm are inseminated. Bifollicular stimulation is required. In other cases, in vitro fertilization should be discussed as the first-line treatment.

Abstract
Objective There are limited data regarding the significance of elevated serum CA-125 level during IUI cycles, even though it is used widely during the initial evaluation of infertile patients. The aim of this study was to investigate the prognostic value of serum CA-125 levels during IUI cycles. Methods Among the patients with controlled ovarian stimulation and IUI cycles at Seoul National University Hospital from Jan 2005 through Dec 2009, 92 cases with no identified endometriotic lesion, ovarian tumor, salpingeal lesion, or uterine myoma were selected. To compare the clinical characteristics between the pregnancy group and the non-pregnancy group, the Mann-Whitney U test and Fisher's exact test were used. Results The overall pregnancy rate was 18.5% (17/92). The pregnancy group showed a higher number of follicles 16 mm in diameter (p=0.036), endometrial thickness (p<0.001), ampules of gonadotropin (p=0.009), and higher body mass index (p=0.022) than the non-pregnancy group. No significant difference was observed in the serum CA-125 level or the proportion of patients with CA-125 exceeding 17 IU/mL between the two groups. Conclusion The prognostic value of serum CA-125 level among infertile patients with IUI cycles is considered limited.

Abstract
To evaluate the influence of female age and cause of infertility on the outcome of controlled ovarian hyperstimulation (COH) and intrauterine insemination (IUI), we studied 2717 COH cycles in 1035 subfertile couples. The cumulative clinical pregnancy rates were 39% and 58% after three and six COH cycles, respectively. The cumulative pregnancy rate significantly decreased with maternal age and differed by cause of infertility. The cumulative pregnancy rate continued to increase with an increase in COH cycle number up to the third, or forth cycle, in patients with mechanical and combined infertility, respectively, and in up to the second cycle in patients aged 40 years or more. These findings provide treatment guidelines for clinicians in determining the likelihood of treatment success and the point at which to proceed to the next treatment strategy.

Abstract
PURPOSE The aim was to determine pregnancy rate following intrauterine insemination (IUI) and its associated factors in a university assisted reproductive technique center in Tehran, Iran. METHODS A retrospective analysis of 350 IUI cycles with ovarian stimulation by clomiphene citrate and/or gonadotropins was performed. RESULTS The overall pregnancy rate was 22% (77/350). Of the 77 pregnancies, 88.3% resulted in live birth, 7.8% in spontaneous abortion, 2.6% in blighted ovum and 1.3% were ectopic. Logistic regression analysis revealed three predictive variables as regards pregnancy: number of the treatment cycle (OR:3.5 CI:1.9 - 6.4 p:0.006), duration of infertility (OR:2.1 CI:1.2 - 3.7 p = 0.001) and age (OR:2.15 CI:1.1 - 4.4 p = 0.04). Pregnancy rate did not have any independent relation to sperm count, type of infertility, number and size of follicle and side of ovulatory ovary. CONCLUSION Our results indicate that clomiphene citrate and/or gonadotropins IUI is a convenient and useful treatment option in women with younger age ( <30 years) and fewer treatment cycles and fewer infertility duration (4 years).

Stimulated intrauterine insemination (SIUI) and donor insemination (DI) as first line management for a selected subfertile population: the Manchester experience. J Assist Reprod Genet 2008; 25:431-6.

Abstract
PURPOSE The objective of our study is to investigate the optimum number of stimulated intrauterine insemination (SIUI) or donor insemination (DI) cycles that can be offered to the couples prior to in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) in a tertiary referral unit for assisted reproduction. METHODS This is a retrospective analysis of 408 SIUI and 704 DI cycles performed in a tertiary referral unit for assisted reproduction. SIUI's were performed by controlled ovarian hyperstimulation and ovulation induction followed by insemination 36 h later. DI's were performed in natural or stimulated cycles after thawing frozen donor sperm. The main outcome measured was cumulative live birth rate (CLBR) per couple. RESULTS A maximum CLBR of 26.1% was achieved after the fourth cycle of SIUI. The CLBR of DI increased to 60.1% in the sixth cycle. CONCLUSIONS This study, in line with a number of other studies, is unable to demonstrate unequivocally whether increasing numbers of IUI or DI cycles are justified clinically or financially. There is a need for larger datasets from multiple centres along with rigorous randomised trials to compare treatment pathways. Until then, the resources spent on the provision of extra SIUI cycles may be better utilized by early referral to IVF.

Abstract
Conflicting results have been published about intra-uterine insemination efficacy. In many studies, success rates is due to ovarian stimulation and number of follicles. In the present fight against multiple pregnancies, ovarian stimulation is discussed and present pregnancy rates are weak. Our aim is to demonstrate that there is a place for the association controlled ovarian hyperstimulation and intra-uterine insemination in the field of infertility treatments. It is possible to try and recognise women at high risk of multiple pregnancies, keeping the benefit of ovarian stimulation.

Abstract
OBJECTIVE To estimate the effects of financial access and other individual characteristics on the likelihood that a woman pursues infertility treatment and the choice of treatment type. DATA SOURCE/STUDY SETTING The 1995 National Survey of Family Growth. STUDY DESIGN We use a binomial logit model to estimate the effects of financial access and individual characteristics on the likelihood that a woman pursues infertility treatment. We then use a multinomial logit model to estimate the differential effects of these variables across treatment types. DATA COLLECTION/EXTRACTION METHOD This study analyzes the subset of 1,210 women who meet the definition of infertile or subfecund from the 1995 National Survey of Family Growth. PRINCIPAL FINDINGS We find that income, insurance coverage, age, and parity (number of previous births) all significantly affect the probability of seeking infertility treatment; however, the effect of these variables on choice of treatment type varies significantly. Neither income nor insurance influences the probability of seeking advice, a relatively low cost, low yield treatment. At the other end of the spectrum, the choice to pursue assisted reproductive technologies (ARTs)-a much more expensive but potentially more productive option-is highly influenced by income, but merely having private insurance has no significant effect. In the middle of the spectrum are treatment options such as testing, surgery, and medications, for which "financial access" increases their probability of selection. CONCLUSIONS Our results illustrate that for the sample of infertile of subfecund women of childbearing age studied, and considering their options, financial access to infertility treatment does matter.

Abstract
We report a case of ovarian stimulation in a woman with a Kallmann-De Morsier syndrome, which resulted in a triple pregnancy and childbirth by caesarean section at 36 weeks of amenorrhea of three girls weighing from 1,950 to 2,300 g. Starting from a literature review of Kallmann-De Morsier syndrome, we discuss the role of LH during the follicular phase and the monitoring of ovarian stimulation.

Abstract
OBJECTIVE To test the hypothesis that anovulatory women would have good pregnancy rates (PRs), regardless of single or multiple follicular development, in response to clomiphene citrate (CC), whereas ovulatory women would have good PRs only when achieving multifollicular responses to CC. DESIGN Retrospective chart review. SETTING University-based infertility center. PATIENT(S) Two hundred and fifty-four women underwent 585 CC-IUI treatment cycles over a 3-year period. INTERVENTION Treatment with CC-IUI. MAIN OUTCOME MEASURE(S) Various factors were examined as predictors of clinical pregnancy rate (CPR) and live-birth rate (LBR) per cycle with the use of logistic regression. RESULT(S) Overall, the CPR was 11.1%, and the LBR was 8.7%. Of 65 clinical pregnancies, 81.5% resulted in live births (singletons, 67.7%; twins, 13.8%). There were no higher-order deliveries. In anovulatory women, the CPR and LBR were 15.7% and 13.6%, respectively. In ovulatory women, the CPR and LBR were 8.8% and 6.3%, respectively. As the number of large follicles increased from one to two, the LBR increased from 6.8% to 10.5%. Regarding the interaction of follicles with ovulatory status, anovulatory women had nearly double the CPR and LBR compared to those in ovulatory women, irrespective of the number of large follicles. CONCLUSION(S) Treatment with CC-IUI is more successful in anovulatory women than in ovulatory women. The multiple follicular response in both ovulatory and anovulatory women increases PRs.

Abstract
BACKGROUND Controlled ovarian hyperstimulation with intrauterine insemination (IUI) is a widely accepted treatment for unexplained and male subfertility. No consensus exists about the drug of first choice to be used as hyperstimulation. This randomized multicentre trial using a parallel design compares the efficacy of clomiphene citrate (CC) with that of recombinant FSH (rFSH). METHODS Couples with primary unexplained or male subfertility were randomized to receive CC or rFSH for ovarian hyperstimulation. The treatment was continued for up to four cycles unless pregnancy occurred. Cycles with more than three follicles were cancelled. Cumulative pregnancy rates and live birth rates were primary outcomes. Cancellation during treatment and multiple birth rates are secondary outcomes. Results were analysed following the intention-to-treat principle. RESULTS Seventy couples with male subfertility and 68 couples with unexplained subfertility were included. Seventy-one women received CC, and 67 received rFSH. Twenty-seven pregnancies were observed in the CC group (38%) and 23 in the rFSH group (34.3%) relative risk (RR) 1.11 [95% confidence interval (95% CI) 0.71-1.73]. The live birth rate was 28.2% (20/71) and 26.9% (18/67) for CC and rFSH, respectively, RR 1.05 (95% CI 0.61-1.80). Overall, the live birth rates per cycle were 10% for CC-stimulated and 8.7% for rFSH stimulated cycles. The total multiple pregnancy rate was 6.0%. Thirty-five cycles (8.6%) were cancelled because of four or more follicles (CC, n = 17; rFSH, n = 18). CONCLUSIONS In couples with primary unexplained or male subfertility participating in an IUI program, ovarian hyperstimulation can be achieved by CC or rFSH. No significant difference in live birth rates between CC and rFSH was observed. Being less expensive, CC seems the more cost-effective drug and therefore, can be offered as drug of first choice.

Abstract
This pilot study was conducted to compare the results of intrauterine insemination (IUI) under ovarian stimulation with either letrozole (Femara) or human menopausal gonadotrophin (HMG). A randomized controlled trial was conducted. Eighty women aged 20-35 years with unexplained infertility of at least 2 years' duration were randomized according to a computer-generated randomization list into the letrozole group and the HMG group. Letrozole was administered at 5 mg/day from day 3 to day 7 of the IUI cycle. HMG injections were started on day 3 at a dose of 75 IU for women under 30 years old and 150 IU for women over 30 years old and monitored periodically by vaginal ultrasound and oestradiol concentrations. The variables selected for analysis were clinical pregnancy rate, endometrial thickness, length of follicular phase and number of preovulatory follicles. No statistically significant difference in clinical pregnancy rates per cycle was found for patients in the letrozole or HMG group (18.4 versus 15.7%). Cost was significantly higher in the HMG stimulation cases (P < 0.001) and no injections were required in the letrozole group. In conclusion, letrozole offers a new treatment regimen in ovarian stimulation regimens for IUI that is cost effective, simple and convenient for the patients.

Abstract
PURPOSE This retrospective study evaluated the role of antral follicle count (AFC) in predicting ovarian response and successful outcome of stimulated insemination cycles. METHODS One-hundred and fifty infertile women with bilateral patent tubes receiving a standard regime of human menopausal gonadotrophin (HMG) in their first cycle were evaluated. Multiple regression analysis was used to evaluate the effects of different parameters on ovarian responses and multiple logistic regression analysis was applied to determine which parameters gave the maximum discrimination to predict clinical pregnancy. RESULTS Body mass index was the only significant parameter to predict the number of follicles > or =14 mm whereas AFC was the only significant parameter to predict the HMG duration. Only the number of follicles > or =14 mm significantly improved the chance of clinical pregnancy with an odds ratio of 1.8. CONCLUSION AFC was related to the HMG duration but was not predictive of number of follicles and clinical pregnancy of stimulated insemination cycles.

Abstract
OBJECTIVE To determine factors responsible for high-order multiple pregnancy (HOMP) and high-order multiple births when multiple cycles of controlled ovarian hyperstimulation-IUI (COH-IUI) are performed. DESIGN Retrospective analysis. SETTING Private infertility clinic. PATIENT(S) Women (n = 2,272) who underwent 4,067 consecutive COH-IUI cycles. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) High-order multiple pregnancy rate, pregnancy rate (PR), and birth rate (PR) per cycle. RESULT(S) High-order multiple pregnancy was related to number of follicles of diameter > or = 10 mm, age, and treatment cycle. For age <32 years, HOMP was 6% for three to six follicles and 20% for seven or more follicles. For ages 32 to 37 years, HOMP was 5% for three to six follicles and 12% for seven or more follicles. In the first COH-IUI cycle, HOMP was 8% for three to six follicles and 15% for seven or more follicles. In the second cycle, HOMP did not occur unless there were more than six follicles. No HOMP occurred after the second cycle. Pregnancy rate did not increase significantly when there were more than four follicles. Continuing COH-IUI past the third cycle resulted in additional pregnancies in patients with one to eight follicles. CONCLUSION(S) High-order multiple pregnancy can be predicted by age and number of follicles of diameter > or = 10 mm. Controlled ovarian hyperstimulation is not necessary to achieve satisfactory overall pregnancy rates if ovulation induction is continued past the third cycle in low responders.

Abstract
With increasing age the probability of ongoing pregnancy established by the use of assisted reproduction technology (ART) decreases. As a result the question arises whether age limits for the application of ART should be established. From a literature review and ongoing research data it appears that the costs per child born greatly increase after the age of 40 for both intrauterine insemination with mild ovarian stimulation and in vitro fertilisation treatment, while in cases of 44 and over, prognosis is flat zero. The willingness to pay for extra costs will greatly determine whether and at what age strict limits should be applied. Fortunately, predictive factors for success, like the antral follicle count, may enable the identification of women over 40 and under 44 that still have favourable prospects, thereby decreasing the necessary costs per childbirth and allowing couples into ART programs that are often denied based solely on female age.

Abstract
OBJECTIVE To compare a short and long interval between hCG administration and IUI after superovulation for the treatment of infertility. DESIGN Prospective, randomized clinical trial. SETTING University hospital-based fertility clinic. PATIENT(S) Patients planning superovulation and IUI for the treatment of infertility. INTERVENTION(S) Patients with >or=2 years of infertility enrolled for superovulation and IUI treatment were randomized to IUI after a short (32-34-hour) or long (38-40-hour) interval after hCG injection. Superovulation was accomplished with hMG or recombinant FSH, with dose adjustment until the maturation of two to five follicles, at which time hCG was given. Sperm was prepared with a gradient centrifugation technique, with IUI performed high up in the uterine fundus. MAIN OUTCOME MEASURE(S) Pregnancy rates. RESULT(S) Of the 348 patient cycles randomized, 270 treatment cycles were initiated. Eighty-one initiated cycles were canceled, leaving 189 completed randomized cycles from 75 patients for analysis. Pregnancy rates were not significantly different between groups. There were pregnancies in 20 of the 96 short hCG-IUI interval cycles (21%) and in 14 of the 93 long hCG-IUI interval cycles (15%) (odds ratio = 0.673, 95% confidence interval 0.297-1.518). CONCLUSION(S) Pregnancy rates are the same after superovulation therapy whether IUI is done after a short or a long interval after hCG injection.

Abstract
OBJECTIVE To determine the relationship between ovarian follicular response (number and diameter of follicles) to ovulation induction agents and pregnancy. DESIGN Retrospective cohort study.Hospital-based center of reproductive medicine. PATIENT(S) Three hundred twenty-two clinically diagnosed infertile couples undergoing 1483 cycles of ovulation induction and IUI. Oral and injectable fertility drugs were administered for 2-10 cycles; ultrasound follicular measurements were recorded around time of ovulation; hCG was administered when follicles were 18-20 mm or more in diameter; IUI was performed 36-40 hours after administration of hCG. MAIN OUTCOME MEASURE(S) A first positive pregnancy test as indicative for conception. Women with follicular diameters >or=20 mm were less likely to become pregnant as compared to women with diameters between 15.00 and 19.99 mm (risk ratio [RR] = 0.58, 95% confidence interval [CI] = 0.35, 0.97). Women >or=30 years of age were half as likely to become pregnant as compared to women <30 years (RR = 0.51, 95% CI = 0.30, 0.85). Likelihood of pregnancy increased by 21% for each prior pregnancy (RR = 1.21, 95% CI = 1.00, 1.47). CONCLUSION(S) Maternal age, gravidity, and follicular diameters around the time of insemination are prognostic factors in the likelihood of pregnancy.

Abstract
OBJECTIVE To determine how advancing female age decreases successful outcomes of intrauterine insemination (IUI) alone or combined with ovarian stimulation. DESIGN Retrospective review. SETTING Academic fertility center. PATIENT(S) Infertile men and women. INTERVENTION(S) Intrauterine insemination alone or combined with ovarian stimulation. MAIN OUTCOME MEASURE(S) Pregnancy rates, miscarriage rates, and live birth rates per insemination cycle according to female age. RESULT(S) The 1,117 cycles of IUI resulted in 217 pregnancies, for an overall pregnancy rate for all female ages of 19.4% and a live birth rate of 12.9% per cycle inseminated. The overall live birth rate per insemination declined with advancing maternal age. CONCLUSION(S) Advancing female age decreases successful outcomes with IUI. The live birth rate with IUI for women 40-42 years old (n = 82) was 9.8% per insemination and may demonstrate that IUI is an appropriate treatment for this age group of women.

Abstract
OBJECTIVE To evaluate the effectiveness of a computerized decision support system for ovarian stimulation with gonadotropins. DESIGN Retrospective and prospective randomized studies. SETTING Private and university teaching hospital. PATIENT(S) Women undergoing ovarian stimulation to treat infertility. MAIN OUTCOME MEASURE(S) Pregnancy rate. RESULT(S) In the retrospective study, computer-generated decisions were compared with clinicians' decisions in 118 stimulated cycles in 53 patients. In 90% of cases, the choice of FSH regimens and adjustments to dosages were identical. In the prospective study, the computer-generated decisions achieved a pregnancy rate per cycle of 18% (15 of 82 cycles), compared with 16% (13 of 82 cycles) achieved by clinicians. CONCLUSION(S) A computerized decision making system was as effective as skilled clinicians in achieving pregnancy by using ovarian stimulation with FSH.

Abstract
BACKGROUND Oral (anti-oestrogens) and injectable (gonadotrophins) ovulation induction agents have been used to increase the number of eggs produced by a woman per cycle in treatment for unexplained subfertility. It is unclear whether there are significant advantages of one type of treatment over the other in this context or in terms of fertility. OBJECTIVES To assess the efficacy of oral versus injectable ovulation induction agents for unexplained subfertility. SEARCH STRATEGY The search strategy of the Menstrual Disorders and Subfertility Group was used for the identification of relevant randomised controlled trials. SELECTION CRITERIA All trials where oral ovulation induction agents were compared with injectable ovulation induction agents in treatment groups generated by randomisation, from couples with unexplained subfertility, were considered for inclusion in the review. DATA COLLECTION AND ANALYSIS Five randomised controlled trials, including a total of 231 identified couples with unexplained subfertility, were found and included in this review. All trials were assessed for quality criteria. The studied outcomes were pregnancy, live birth, miscarriage, multiple birth, occurrence of ovarian hyperstimulation syndrome and cycle cancellation. MAIN RESULTS Where trials with important co-interventions were excluded, there was no significant difference in the odds of beneficial outcomes for oral versus injectable ovulation induction agents - live birth per couple (OR 0.06, 95%CI 0.00-1.15), pregnancy per woman (OR 0.33, 95%CI 0.09-1.20); nor of detrimental outcomes for injectable versus oral agents - miscarriage (OR 0.11, 95%CI 0.00-2.84); there were no reported cases of multiple births, cases of ovarian hyperstimulation or discontinued cycles consequent upon overstimulation. Where trials with the co-intervention of a human chorionic gonadotrophin trigger injection (given only in the injectable ovulation induction agent treatment arm) were not excluded there was no significant difference in the odds of live birth per couple (OR 0.40, 95%CI 0.15-1.08). However oral ovulation induction agents had significantly reduced odds of pregnancy per woman compared to injectable ovulation induction agents (OR 0.41, 95%CI 0.17-0.80). For detrimental outcomes, there were no significant differences in the odds of miscarriage (OR 0.61, 95%CI 0.09-4.01) and multiple birth (OR 1.08, 95%CI 0.16-7.03) for injectable versus oral agents. No data were available concerning the occurrence of ovarian hyperstimulation syndrome nor cycle cancellation. REVIEWER'S CONCLUSIONS There is insufficient evidence to suggest that oral agents are inferior or superior to injectable agents in the treatment of unexplained subfertility. Information on harms is sketchy, and remains compatible with large differences in either direction. Much larger trials than have previously been undertaken are required to provide information on relative harms as well as benefits.

Abstract
The aim of this study was to evaluate the impact of male and female factors on the pregnancy rate in an intrauterine insemination (IUI) programme. Data on 522 cycles were retrospectively studied. All patients 39 years or younger were included in the study where data were available on male and female diagnosis, as well as on ovulation induction methodology. Regression analysis was possible on 495 cycles to study different factors affecting the pregnancy rate per treatment cycle. Logistic regression identified variables which were related to outcome and were subsequently incorporated into a statistical model. The number of follicles was found to have a linear association with the risk ratio (chance) of pregnancy. The age of the woman was also found to have a linear (negative) association with pregnancy. The percentage motility and percentage normal morphology (by strict criteria) of spermatozoa in the fresh ejaculate were the male factors that significantly and independently predicted the outcome. Percentage motility > or = 50 was associated with a risk ratio of pregnancy of 2.95 compared to percentage motility < 50. Percentage normal sperm morphology > 14% was associated with a risk ratio of pregnancy of 1.8 compared to percentage normal morphology < or = 14%. Female patients with idiopathic infertility were divided into three groups according to normal sperm morphology. The pregnancy rate per cycle was 2.63% (1/38) for the P (poor) pattern group (0-4% normal forms), 11.4% (17/149) for the G (good) pattern group (5-14%), and 24% (18/75) for the N (normal) pattern group (> 14% normal forms). A female diagnosis of endometriosis or tubal factor impacted negatively on the probability of pregnancy (risk ratio of 0.17), compared with other female diagnoses. Male and female factors contribute to pregnancy outcome, but the clinician can influence prognosis by increasing the number of follicles, especially in severe male factor cases.

Abstract
The study was conducted to evaluate the results of IUI treatment in a homogenous group with male factor infertility, and to assess the correlation of sperm variables, including sperm morphology by strict criteria, with pregnancy achievement after IUI. A total of 108 couples with no apparent female aetiology for infertility underwent 264 intrauterine insemination treatment cycles. A comparison was made between the sperm variables in two groups in which the achievement of pregnancy differed. The percentage of motile spermatozoa, degree of motility and normal morphology (by strict criteria) were significantly higher in the pregnant group compared with that of the nonpregnant group. A significant difference in pregnancy rates per couple after intrauterine insemination was demonstrated among three groups according to the percentage of sperm morphology, i.e. poor (< 4%), fair (4-14%) or good (> 14%) (11.1%; 36.1% and 50.0%, respectively). Intrauterine insemination is a valid mode of treatment in cases with male infertility, provided that normal morphology by strict criteria is higher than 4%.

Abstract
OBJECTIVE To investigate the optimum number of cycles of controlled ovarian hyperstimulation and intrauterine insemination in the treatment of unexplained infertility. DESIGN Observational prospective study. SETTING In vitro fertilization embryo transfer center. PATIENT(S) Five hundred ninety-four couples with unexplained infertility. INTERVENTION(S) Controlled ovarian hyperstimulation (COH), intrauterine insemination (IUI), in vitro fertilization (IVF), and intracytoplasmic sperm injection (ICSI). MAIN OUTCOME MEASURE(S) Cycle fecundity. RESULT(S) One to 3 cycles of COH/IUI were performed in 594 patients (group A) undergoing 1,112 cycles (mean, 1.9 cycles/patient). Up to 3 further trials (cycles 4-6) of COH/IUI were then performed in 91 of these women (group B), a total of 161 cycles (mean, 1.8 cycles/patient). A historical comparison group C consisted of 131 patients with 3 failed cycles of COH/IUI who underwent 1 cycle of IVF and ICSI at our center. In group A, 182 pregnancies occurred, with a cycle fecundity of 16.4% and a cumulative pregnancy rate (PR) of 39.2% after the first 3 cycles. In group B, 9 pregnancies occurred in cycles 4-6, with a cycle fecundity of 5.6%, significantly lower than that of group A (P<.001). The cumulative PR rose to 48.5% by cycle 6, a further increase of only 9.3%. In the women undergoing IVF and ICSI in group C, 48 pregnancies occurred, with a cycle fecundity of 36.6% per cycle, significantly higher than that of group B (P<.001). CONCLUSION(S) In unexplained infertility, the cycle fecundity in the first three trials of COH and IUI was higher than in cycles 4-6, with a statistically significant difference. Patients should be offered IVF or ICSI if they fail to conceive after three trials of COH and IUI.

Abstract
Performance of intra-uterine insemination (IIU) is generally advocated as a first line therapy for infertility related to cercical hostility, male factor, unexplained infertility or mild endometriosis. IIU are usually performed following stimulation of ovulation, even in absence of anovulation. However the rationale for such a systematic ovulation induction is still questionable. Indeed, while an overall assessment of ovarian stimulation tends to conclude to a beneficial effect of these treatments in unexplained or some male infertility, it is clear that no definitive conclusion can be drawn. Indeed, the methodology in many published series is mostly inadequate, data are usually not analysed according to the type of infertility or to the female hormonal features. Finally, adverse effects are imperfectly descripted. A more accurate analysis of these data in relation to the number of recruited follicles definitively shows that, if a bifollicular development is associated with a significant increase in the pregnancy rates, there is no advantage to stimulate further the ovary. Indeed, surpassing the recruitment of two follicles would lead to dramatically increase the risk of OHSS and multiple pregnancies. Thus, further investigations including prospective, randomized studies are needed to better define what should be the most adequate regimen of ovulation induction. Specifically, tailoring the rate of multifollicular development according to the duration, the type of infertility (etiology; primary or secondary; female age) would prove to be a safer approach for getting pregnancy as well as avoiding adverse effects. Such a policy remains to be determined in the light of further clinical studies conducted in the more appropriate manner.

Abstract
OBJECTIVE To evaluate the effects of 10 minutes of bed rest after intrauterine insemination (IUI) on the pregnancy rate. DESIGN Prospective randomized study. SETTING University teaching hospital. PATIENT(S) One hundred sixteen couples with unexplained infertility. INTERVENTION(S) Patients were prospectively randomized either to immediate mobilization after IUI (group I) or to remain in a supine position for 10 minutes after the procedure (group II). MAIN OUTCOME MEASURE(S) Cumulative pregnancy rate. RESULT(S) Ninety-five couples were included in the analysis. Group I consisted of 40 couples (90 cycles), and group II consisted of 55 couples (120 cycles). The pregnancy rate per couple in group I (4 of 40 [10%]) was significantly lower than in group II (16 of 55 [29%]). The pregnancy rate per cycle in group I (4.4%) was also lower than in group II (13. 3%). With use of life-table analysis, the cumulative probability of pregnancy in group II was significantly higher than in group I. CONCLUSION(S) A 10-minute interval of bed rest after IUI has a positive effect on the pregnancy rate. We recommend that mandatory bed rest for 10 minutes after IUI should be adopted into a standard practice.

Abstract
We analysed 12,100 consecutive cycles of artificial insemination by donor spermatozoa in 1901 infertile couples. In our analysis, particular attention was given to finding an appropriate way of taking into account the respective effects of female and male factors on the pregnancy success rate and the level at which these factors act (cycle vs. woman and donation vs. donor). A total of 1213 pregnancies occurred. The pregnancy rate per cycle was lower as the age of the woman increased (p < 0.0001) and varied with the type of infertility: fecundity was higher (p = 0.03) in the case of azoospermia than of severe oligozoospermia. After taking into account these factors, significant unexplained variation in likelihood to conceive remained. A part of this heterogeneity was shown to be due to variation in fecundability between semen donors. In order to explain this heterogeneity between donors, compositional covariates were used, particularly the mean of results of the semen analysis performed for donations from the same donor. For each semen characteristic, the overall mean of the different donations of a donor was an important predictive factor of successful insemination: after taking into account all of the other factors, the odds ratios for an increase of 50 x 10(6)/mL spermatozoa, of a 20% increase in sperm motility and of a 2 point increase in the post-thaw quality index, were, respectively, 1.13, 1.37 and 1.56. After adjustment for these factors, the specific characteristics of each semen donation were no longer significantly predictive of successful insemination. This observation has a biological interpretation: sperm with low parameters but produced by a normally fertile man can have a satisfactory success rate.
