A large observational data study supporting the PROsPeR score classification in poor ovarian responders according to live birth outcome. Hum Reprod 2021; 36:1600-1610. [PMID: 33860313 DOI: 10.1093/humrep/deab050] [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: 09/23/2019] [Revised: 01/22/2021] [Indexed: 11/13/2022] Open
Abstract
STUDY QUESTION Can the Poor Responder Outcome Prediction (PROsPeR) score identify live birth outcomes in subpopulations of patients with poor ovarian response (POR) defined according to the ESHRE Bologna criteria (female age, anti-Müllerian hormone (AMH), number of oocytes retrieved during the previous cycle (PNO) after treatment with originator recombinant human follitropin alfa? SUMMARY ANSWER The PROsPeR score discriminated the probability of live birth in patients with POR using observational data with fair discrimination (AUC ≅ 70%) and calibration, and the AUC losing less than 5% precision compared with a model developed using the observational data. WHAT IS KNOWN ALREADY Although scoring systems for the likelihood of live birth after ART have been developed, their accuracy may be insufficient, as they have generally been developed in the general population with infertility and were not validated for patients with POR. The PROsPeR score was developed using data from the follitropin alfa (GONAL-f; Merck KGaA, Darmstadt, Germany) arm of the Efficacy and Safety of Pergoveris in Assisted Reproductive Technology (ESPART) randomized controlled trial (RCT) and classifies women with POR as mild, moderate or severe, based upon three variables: female age, serum AMH level and number of oocytes retrieved during the previous cycle (PNO). STUDY DESIGN, SIZE, DURATION The external validation of the PROsPeR score was completed using data derived from eight different centres in France. In addition, the follitropin alfa data from the ESPART RCT, originally used to develop the PROsPeR score, were used as reference cohort. The external validation of the PROsPeR score l was assessed using AUC. A predetermined non-inferiority limit of 0.10 compared with a reference sample and calibration (Hosmer-Lemeshow test) were the two conditions required for evaluation. PARTICIPANTS/MATERIALS, SETTING, METHODS The observational cohort included data from 8085 ART treatment cycles performed with follitropin alfa in patients with POR defined according to the ESHRE Bologna criteria (17.6% of the initial data set). The ESPART cohort included 477 ART treatment cycles with ovarian stimulation performed with follitropin alfa in patients with POR. MAIN RESULTS AND THE ROLE OF CHANCE The external validation of the PROsPeR score to identify subpopulations of women with POR with different live birth outcomes was shown in the observational cohort (AUC = 0.688; 95% CI: 0.662, 0.714) compared with the ESPART cohort (AUC = 0.695; 95% CI: 0.623, 0.767). The AUC difference was -0.0074 (95% CI: -0.083, 0.0689). This provided evidence, with 97.5% one-sided confidence, that there was a maximum estimated loss of 8.4% in discrimination between the observational cohort and the ESPART cohort, which was below the predetermined margin of 10%. The Hosmer-Lemeshow test did not reject the calibration when comparing observed and predicted data (Hosmer-Lemeshow test = 1.266688; P = 0.260). LIMITATIONS, REASONS FOR CAUTION The study was based on secondary use of data that had not been collected specifically for the analysis reported here and the number of characteristics used to classify women with POR was limited to the available data. The data were from a limited number of ART centres in a single country, which may present a bias risk; however, baseline patient data were similar to other POR studies. WIDER IMPLICATIONS OF THE FINDINGS This evaluation of the PROsPeR score using observational data supports the notion that the likelihood of live birth may be calculated with reasonable precision using three readily available pieces of data (female age, serum AMH and PNO). The PROsPeR score has potential to be used to discriminate expected probability of live birth according to the degree of POR (mild, moderate, severe) after treatment with follitropin alfa, enabling comparison of performance at one centre over time and the comparison between centres.

IVF outcomes in patients with a history of bariatric surgery: a multicenter retrospective cohort study. Hum Reprod 2021; 35:2755-2762. [PMID: 33083823 PMCID: PMC7744158 DOI: 10.1093/humrep/deaa208] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2020] [Revised: 07/13/2020] [Indexed: 02/06/2023] Open
Abstract
STUDY QUESTION How does a history of dramatic weight loss linked to bariatric surgery impact IVF outcomes? SUMMARY ANSWER Women with a history of bariatric surgery who had undergone IVF had a comparable cumulative live birth rate (CLBR) to non-operated patients of the same BMI after the first IVF cycle. WHAT IS KNOWN ALREADY In the current context of increasing prevalence of obesity in women of reproductive age, weight loss induced by bariatric surgery has been shown to improve spontaneous fertility in obese women. However, little is known on the clinical benefit of bariatric surgery in obese infertile women undergoing IVF. STUDY DESIGN, SIZE, DURATION This exploratory retrospective multicenter cohort study was conducted in 10 287 IVF/ICSI cycles performed between 2012 and 2016. We compared the outcome of the first IVF cycle in women with a history of bariatric surgery to two age-matched groups composed of non-operated women matched on the post-operative BMI of cases, and non-operated severely obese women. PARTICIPANTS/MATERIALS, SETTING, METHODS The three exposure groups of age-matched women undergoing their first IVF cycle were compared: Group 1: 83 women with a history of bariatric surgery (exposure, mean BMI 28.9 kg/m2); Group 2: 166 non-operated women (non-exposed to bariatric surgery, mean BMI = 28.8 kg/m2) with a similar BMI to Group 1 at the time of IVF treatment; and Group 3: 83 non-operated severely obese women (non-exposed to bariatric surgery, mean BMI = 37.7 kg/m2). The main outcome measure was the CLBR. Secondary outcomes were the number of mature oocytes retrieved and embryos obtained, implantation and miscarriage rates, live birth rate per transfer as well as birthweight. MAIN RESULTS AND THE ROLE OF CHANCE No significant difference in CLBR between the operated Group 1 patients and the two non-operated Groups 2 and 3 was observed (22.9%, 25.9%, and 12.0%, in Groups 1, 2 and 3, respectively). No significant difference in average number of mature oocytes and embryos obtained was observed among the three groups. The implantation rates were not different between Groups 1 and 2 (13.8% versus 13.7%), and although lower (6.9%) in obese women of Group 3, this difference was not statistically significant. Miscarriage rates in Groups 1, 2 and 3 were 38.7%, 35.8% and 56.5%, respectively (P = 0.256). Live birth rate per transfer in obese patients was significantly lower compared to the other two groups (20%, 18%, 9.3%, respectively, in Groups 1, 2 and 3, P = 0.0167). Multivariate analysis revealed that a 1-unit lower BMI increased the chances of live birth by 9%. In operated women, a significantly smaller weight for gestational age was observed in newborns of Group 1 compared to Group 3 (P = 0.04). LIMITATIONS, REASONS FOR CAUTION This study was conducted in France and nearly all patients were Caucasian, questioning the generalizability of the results in other countries and ethnicities. Moreover, 950 women per group would be needed to achieve a properly powered study in order to detect a significant improvement in live birth rate after bariatric surgery as compared to infertile obese women. WIDER IMPLICATIONS OF THE FINDINGS These data fuel the debate on the importance of pluridisciplinary care of infertile obese women, and advocate for further discussion on whether bariatric surgery should be proposed in severely obese infertile women before IVF. However, in light of the present results, infertile women with a history of bariatric surgery can be reassured that surgery-induced dramatic weight loss has no significant impact on IVF prognosis. STUDY FUNDING/COMPETING INTEREST(S) This work was supported by unrestricted grants from FINOX-Gédéon Richter and FERRING Pharmaceuticals awarded to the ART center of the Clinique Mathilde to fund the data collection and the statistical analysis. There are no conflicts of interest to declare. TRIAL REGISTRATION NUMBER NCT02884258.

Disparities in reproductive outcomes according to the endometrial preparation protocol in frozen embryo transfer : The risk of early pregnancy loss in frozen embryo transfer cycles. J Assist Reprod Genet 2017; 35:425-429. [PMID: 29110260 DOI: 10.1007/s10815-017-1078-0] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2017] [Accepted: 10/24/2017] [Indexed: 12/19/2022] Open
Abstract
PURPOSE The purpose of this study was to determine the effect of stimulated and artificial endometrial preparation protocols on reproductive outcomes in frozen embryo transfer (FET) cycles. METHODS We performed a retrospective study of 1926 FET cycles over a 3.5-year period in the Fertility Unit at a University Hospital. Stimulated and artificial protocols were used for endometrial preparation. The embryos for FET were obtained from either in vitro fertilization or intracytoplasmic sperm injection cycles. Live birth rate and early pregnancy loss rates were retrospectively compared. In artificial protocols, oral or vaginal administration of oestradiol 2 mg two or three times a day was followed by vaginal supplementation with progesterone 200 mg two or three times a day. In stimulated protocols, recombinant follicle-stimulating hormone was administered from day 4 onward. Vaginal ultrasound was used for endometrial and ovarian monitoring. A pregnancy test was performed 14 days after FET. If it was positive, oestradiol and progesterone were administered up until the 12th week of gestation in artificial cycles. We defined early pregnancy losses as biochemical pregnancies (preclinical losses) and miscarriages. RESULTS Data on 865 artificial cycles (45% of the total) and 1061 stimulated cycles (55%) were collected. Early pregnancy loss rate was significantly lower for stimulated cycles (34.2%) than for artificial cycles (56.9%), and the live birth rate was significantly higher for stimulated cycles (59.7%) than for artificial cycles (29.1%). CONCLUSION In frozen embryo transfer, artificial cycles were associated with more early pregnancy loss and lower live birth rate than stimulated cycles.

High-magnification selection of spermatozoa prior to oocyte injection: confirmed and potential indications. Reprod Biomed Online 2013; 28:6-13. [PMID: 24268730 DOI: 10.1016/j.rbmo.2013.09.019] [Citation(s) in RCA: 38] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2013] [Revised: 09/04/2013] [Accepted: 09/05/2013] [Indexed: 11/17/2022]
Abstract
Intracytoplasmic morphologically selected sperm injection (IMSI) involves the use of differential interference contrast microscopy at high magnification (at least ·6300) to improve the observation of live human spermatozoa (particularly by showing sperm head vacuoles that are not necessarily seen at lower magnifications) prior to intracytoplasmic sperm injection (ICSI) into the oocyte. However, a decade after IMSI’s introduction, the technique’s indications and ability to increase pregnancy and/or birth rates (relative to conventional ICSI) are subject to debate. In an attempt to clarify this debate, this work performed a systematic literature review according to the PRISMA guidelines. The PubMed database was searched from 2001 onwards with the terms ‘IMSI’, ‘MSOME’ and ‘high-magnification, sperm’. Out of 168 search results, 22 relevant studies reporting IMSI outcomes in terms of blastocyst, pregnancy, delivery and/or birth rates were selected and reviewed. The studies’ methodologies and results are described and discussed herein. In view of the scarcity of head-to-head IMSI versus ICSI studies, the only confirmed indication for IMSI is recurrent implantation failure following ICSI. All other potential indications of IMSI require further investigation.

Abstract
STUDY QUESTION Do TNF-308 and -238 polymorphisms impact the embryo implantation rate after in vitro fertilization (IVF) in women without female infertility factor? SUMMARY ANSWER The presence of the TNF-308A allele is associated with high implantation and multiple pregnancy rates in women without known infertility factors after ovarian hyperstimulation with exogenous FSH. WHAT IS ALREADY KNOWN Multiple pregnancies are frequent after the use of Assisted Reproductive Technologies. Single embryo transfer (SET) has been proposed as a simple way to prevent these risks. However, the extension of SET indications to patients not selected based on specific criteria is controversial because of reduced pregnancy rates. To date, the predictive value of the parameters used for SET (age, gynecological history of the patient and uterine characteristics) allows a pregnancy rate of ~30%. STUDY DESIGN, SIZE, DURATION The potential predictive value of TNF polymorphisms (-308, rs1800629 and -238, rs361525) on implantation rate was evaluated in 424 women requiring IVF due to male fertility factors. This cohort retrospective study was conducted over 4 years in University-affiliated hospitals. PARTICIPANTS, SETTING, METHODS The entire patient group included 424 women undergoing intracytoplasmic sperm injection (ICSI) due to male fertility factors without the contribution of any female factor. From among this group, a selected patient group included 120 women with a normal karyotype, age under 38 years, serum follicle-stimulating hormone (Day-3 FSH) levels below 10 IU/l, a long agonist desensitization protocol associated with recombinant FSH treatment and a Caucasian background. MAIN RESULTS AND THE ROLE OF CHANCE The TNF-238 polymorphism was not associated with implantation rate. In contrast, the presence of the TNF-308A allele was associated with increased Day 3-E2 levels as well as higher implantation and multiple pregnancy rates after fresh embryo transfer in women from the entire and selected patient groups. Moreover, in the selected patient group, the presence of the TNF-308A allele was also associated with a decrease in the miscarriage rate. The benefit of the TNF-308A allele in predicting implantation rates was not observed after the use of frozen embryos. LIMITATIONS, REASONS FOR CAUTION Future studies are needed to evaluate whether the TNF-308A allele might also be a biomarker in women with infertility factors. WIDER IMPLICATIONS OF THE FINDING The TNF-308A allele may represent a good candidate for a potential predictive, non-invasive biomarker in the SET strategy. However, its impact should be evaluated in prospective studies. STUDY FUNDING/COMPETING INTEREST This study was conducted with financial support from the French Institute for Health and Medical Research (INSERM), Organon France for a FARO (Fond d'Aide à la Recherche Organon) fellowship (to V.T.) and CHU Nice PHRC (PHRC 09-279).There are no competing interests.

Abstract
Résumé
Introduction
Dans l’azoospermie obstructive (AO), les taux d’extraction chirurgicale de spermatozoïdes sont élevés. Cependant, en ce qui concerne les issues des ICSI (Intra cytoplasmic Sperm Injection) chirurgicales, les données de la littérature divergent. Quels sont, dans notre équipe, les taux d’extraction de spermatozoïdes après aspiration épidydimaire (MESA) et après extraction testiculaire (TESE) dans l’AO ? Les taux de grossesses, les taux de fausses couches spontanées et d’accouchements diffèrent-ils en fonction de l’origine du sperme ?
Matériels et méthodes
L’étude a rétrospectivement inclus 48 couples dont l’homme présente une azoospermie obstructive pure et ayant bénéficié d’un prélèvement chirurgical de spermatozoïdes associant systématiquement MESA et TESE. Les ICSI ont été réalisées de manière asynchrone. À chaque fois que cela était possible, la première ICSI a été réalisée avec des spermatozoïdes épididymaires.
Résultats
Pour les 48 couples, 99 ICSI ont été réalisées. Quinze couples ont réalisé 24 ICSI-TESE car l’aspiration épididymaire était négative. Onze couples ont réalisé 20 ICSI-TESE car la qualité du prélèvement épididymaire n’était pas satisfaisante (vitalité spermatique réduite le plus souvent). Vingt-deux couples ont réalisé 22 ICSI-MESA en première intention puis en cas d’échec, 11 couples ont réalisé 12 ICSI-MESA et dix couples ont réalisé 20 ICSI-TESE. Alors que les nombres d’ovocytes injectés (7,1±4,1 vs 6,9 ±3,6 P: 0,8) et d’embryons obtenus (4,5±3,0 vs 4,7±2,7; P: 0,7) ne sont pas significativement différents dans les deux groupes d’ICSI, les nombres d’embryons de top qualité (2,4±1,9 vs 3,6±2,0 P: 0,005) et d’embryons congelés (0,9±1,8 vs 1,7±1,9 P: 0,04) sont significativement supérieurs dans le groupe TESE. Le nombre de grossesse par ponction est supérieur dans le groupe TESE (58,5 % vs 26,5 %, P: 0,002).
Conclusion
L’approche de notre centre a la particularité d’associer systématiquement un prélèvement testiculaire au prélèvement épididymaire chez tout homme présentant une azoospermie obstructive alors que la plupart des autres études rapportées se limitent à l’exploration épididymaire si cette dernière est positive lors de l’examen extemporané. Alors que classiquement, on rapporte 100% de positivité lors du prélèvement épididymaire chez l’homme atteint d’une azoospermie obstructive, dans notre étude, plus de la moitié des explorations épididymaires s’est avérée inexploitable. La qualité embryonnaire et les taux de grossesses sont meilleurs avec des spermatozoïdes testiculaires. L’association de ces 2 sites de prélèvement (MESA et TESE) peut être complémentaire et utile pour le couple et l’issue de sa prise en charge en AMP sans pour autant entraîner un sur-risque pour l’homme dans les suites de la chirurgie.

Abstract
This research aims to study the experiences and the maternal representations of infertile women throughout the different steps of a medically assisted procreation (MAP) with oocyte donation. The analysis of collected data (interviews and questionnaires) shows that the resort of egg donation creates psychic adjustment (particularly in terms of maternal representations) that appear specific to this type of procreation.

Abstract
Since the inception of Assisted Reproductive Technology (ART), knowing the moment of ovulation has always been a priority. Initially, the monitoring was accomplished by observing the luteinizing hormone (LH) surge just before ovulation. Currently, in all ART facilities, the monitoring of all stimulated ovulatory cycles is done by using the conventional two-dimensional (2D) ultrasound to measure follicle diameter and by drawing blood tests that measure estradiol, progesterone, and luteinizing hormone levels. These exams allow determination of the numbers and quality of growing ovarian follicles and evaluation of follicle maturity before choosing the appropriate time for ovulation triggering. The monitoring of ovulatory cycles has now become enhanced with the arrival of new software called SonoAVC. This software allows the utilization of 3D blocks to immediately calculate the total number and volume of the follicles inside the ovary. This automatic approach is faster, precise, and more efficient. It also has better reproducibility than the classical 2D diameters. Furthermore, certain ART professionals envision that by using the SonoVac technology, patients will no longer need to be monitored with regular ultrasounds and with systematic hormonal testing.

Abstract
PURPOSE Implantation failure is known to be associated with an increased risk of aneuploidy in embryos, a situation leading to a pre-implantation genetic screening, not allowed in different countries like France. Our aim was to evaluate the gamete aneuploidy incidence in this context, using first polar body and spermatozoa aneuploidy screening. METHODS Three groups were considered: 11 couples with pregnancy obtained after IVF for female infertility (group 1); 20 couples with pregnancy obtained after IVF for male infertility (group 2); and 35 couples with implantation failure (group 3). In group 3, 28 couples treated by ICSI volunteered for first polar body analysis (PB1). RESULTS Spermatozoa aneuploidy rate was increased in groups 2 (1.6%) and 3 (2.1%) in comparison to group 1 (0.6%). PB1 aneuploidy rate was 35.4% in group 3. Finally, eight couples (32%) had no particular chromosomal risk in gametes, 15/25 (60%) presented an increased spermatic (>2%) or oocyte (>1/3) aneuploidy rate, and 2/25 (8%) had both. CONCLUSION Those results confirm that implantation failure has a heterogeneous origin, that gamete chromosome abnormality rate is one of the major contributing factors, and that 1st Polar body and spermatozoa aneuploidy screening or pre-implantation genetics screening may be indicated for these couples.

Abstract
Serum prolactin measurement is usually performed in infertility evaluation, even if there's no specific clinical presentation of hyperprolactinemia. High levels of prolactin are noted in 20 to 30% of menstrual abnormalities and in about 10% of regular menses. It is of importance to determine whether hyperprolactinemia is related to pituitary adenoma, drug administration, general diseases, or circulating large forms of prolactin, in order to avoid heavy, expensive, time consuming and unnecessary clinical investigations or therapeutic actions. We must first to confirm the biological diagnosis of hyperprolactinemia with few repeated plasmatic measurements, and, later, if necessary use TRH-metoclopramide test and/or pituitary magnetic resonance imaging.

Abstract
Smoking reduce the natural fertility and the delay to conceive increase with the number of cigarettes. In In Vitro Fertilization, the pregnancy rates per cycle are reduced with smokers compared with no smokers (OR: 0.66). The menopause arrive on average 2 years before with the smokers and the damages of ovarian reserve increase with smoking. The deleterious effects on ovary arrive, early in utero with regard to maternal smoking, and after the puberty, on the pre-ovulatory period where toxic, vascular and mutagen effects induce inhibition of ovocyte apoptosis, promoting ovocyte aneuploidy and subsequently miscarriage. The protection of ovarian fertility is one argument more to stop early smoking.

Abstract
BACKGROUND A case of idiopathic primary infertility was attributed to a block in oocyte meiosis affecting the transition between metaphase I and metaphase II. METHODS AND RESULTS A couple suffering unexplained primary infertility was unsuccessfully treated by various means of assisted reproductive technology. After four unsuccessful pregnancy attempts using intrauterine inseminations (IUI), IVF was attempted (all oocytes remained unfertilized), followed by an ICSI cycle. None of the retrieved oocytes expelled the polar body, and therefore were not injected. The failure of these assisted reproduction cycles was, in both cases, due to the immaturity of the oocytes recovered. Cytogenetic analysis of the oocytes retrieved for ICSI provided evidence of meiotic arrest. Using cytogenetic staging criteria we were able to show that this arrest occurred between metaphase I and anaphase I. CONCLUSIONS Meiotic blocks affecting oocytes have already been described for various mammals. We discuss here mechanisms that might be involved in this possibly inherited disorder in humans, and ways in which our knowledge of them could be increased.

Abstract
OBJECTIVE To compare the different donor insemination technics. MATERIAL AND METHOD Analysis of the published studies about donor insemination which value the effectiveness of Intra Cervical Insemination (ICID) and Intra Uterine Insemination (IUID), the interest of ovulation induction, the possible complications, and the cost-effectiveness ratio. RESULTS The meta-analysis of the Cochrane data base (10 comparative studies IUID versus ICID, 2568 donor insemination cycles) lead to a pregnancy rate per cycle (PRC) 17.77% with IUID versus 7.68% with ICID. The odds ratio is 2.63 (CI from 1.85 to 3.73). With these PRC, the direct cost per evolutive pregnancy is 54,780 F with ICID and 25,675 F with IUID. CONCLUSION If it is possible to propose ICID to patient with an excellent regularity of ovulation. IUID with ovulation induction by gonadotropins is today the gold standard, and more especially as the law restrict the number of donor inseminations. Indeed, the IUID is two or three times more effective than ICID, consume the half of sperm straws, use a semen of moderate quality, there is no complication provided that the cycle is cancelled if there is more than two mature follicles and the cost-effectiveness ratio is greatly in favour with IUID.

Abstract
OBJECTIVE To determine the effect of hydrosalpinges on the pregnancy rate in an IVF program. DESIGN Multicentric retrospective analysis of clinical and laboratory data. SETTING Two assisted reproductive technology centers in university hospitals. PATIENT(S) Four hundred forty-three women, under 38 years of age, with pure tubal infertility. The patients were classified into the following five groups: bilateral hydrosalpinges (n = 37), unilateral hydrosalpinx (n = 54), bilateral tubal occlusion (n = 207), unilateral tubal occlusion (n = 55), and severe tubal disease without complete occlusion (n = 90). MAIN OUTCOME MEASURE(S) Pregnancy and implantation rates. RESULT(S) The pregnancy and the implantation rates per transfer (12.3% and 5.4%) obtained by women with bilateral hydrosalpinges are significantly lower than the rates (means = 23.1% and 12%) for all other tubal infertility groups. CONCLUSION(S) Bilateral hydrosalpinges have a deleterious effect on the outcome of IVF program.

Abstract
We studied the prognostic value of sperm characteristics for the outcome of intra-uterine insemination with partner sperm (IUIPS). A total of 712 cycles of IUIPS following induction of ovulation with gonadotrophin (hMG/hCG) for 277 sterile couples attending the assisted reproductive technology centre of Poissy Hospital (78300-France) between January 1991 and December 1994 was studied retrospectively. Ninety-two clinical pregnancies were obtained giving an overall rate of 12.9% per cycle. None of the characteristics of the sperm as assessed initially correlated with outcome. In contrast, the number of motile spermatozoa given (n) affected outcome: for n < 1 x 10(6) the pregnancy rate was 2%; for n = 5 to 8 x 10(6) the rate was 19%. However, for +/- 8 x 10(6) the proportion of biochemical pregnancies and miscarriages was 40% which was significantly higher than for smaller concentration. The resort of IVF following 4 IUIPS failures leads to a pregnancy rate per cycle of only 6.7%.

Abstract
From March 1990 to September 1993, 20 women underwent a total of 89 cycles of intracervical inseminations with donor semen (ICI) and 23 women underwent 67 cycles of intrauterine inseminations with donor semen (IUI). The women were assigned to the two groups randomly, but ensuring that the ages of the women and pathologies of the male partner (azoospermia or severe oligozoospermia) were similar in the two groups. There was no significant difference between the characteristics of the two groups and the method used to induce ovulation (HMG/HCG) was identical. Two semen straws were used for each insemination cycle. Semen was prepared for IUI on a Percoll gradient. Thirteen clinical pregnancies were obtained in the IUI group (19.4% of the attempts) and six in the ICI group (6.75%). After six cycles of insemination, 75.4% of the women of the IUI group obtained a pregnancy, as compared to 35% in the ICI group. These good results may be due to the method of induction of ovulation, but also to the technique itself, increasing the number of motile spermatozoa at the site of fertilization. The time taken to obtain a pregnancy is thus shorter with IUI than with ICI, and the number of semen straws required is smaller. In-vitro fertilization (IVF) should be proposed after six failures by IUI.

Abstract
The results of 109 intra-uterine inseminations with cryopreserved prepared donor semen (IUId) in stimulated cycles, performed among 42 couples from November 1987 to June 1991, were analysed. The single IUId was performed 39 +/- 3 hours after the injection of human chorionic gonadotrophin. For each IUID 1,25 +/- 1.4 x 10(6) motile spermatozoa (mean +/- standard deviation) were inseminated. 27 pregnancies were obtained and the pregnancy rate per cycle was 24.8%. The number of motile spermatozoa inseminated was significantly higher in the group of pregnant women than in the population without pregnancy (1.64 x 10(6) x 10(6)/IUI versus 1.13 x 10(6)/IUI). The sperm count and the number of motile spermatozoa inseminated were significantly higher when the semen was prepared on discontinuous Percoll gradients than after swim-up in Menezo B2 medium (8.2 x 10(6)/ml versus 4.3 x 10(6)/ml and 1.7 x 10(6) versus 0.77 x 10(6)). Among the 27 clinical pregnancies, 3 were twins and 2 were triplets. The ovarian hyperstimulation associated with the use of a prepared semen of donor, generate a high risk of multiple pregnancies. To improve the results without increasing the risk of multiple pregnancies, we propose to inseminate about 1.5 x 10(6) motile spermatozoa with a maximum plasma estradiol level of 1 100 pg/ml, on the day of hCG injection, associated with 2 preovulatory follicles. This technique may augment the rate of pregnancy and represents an appreciable time gain. These results must be confirmed by randomized prospective studies.

Abstract
Serum ferritin, haemoglobin, erythrocyte constants, serum iron and the fixation capacity of transferrin were determined in 233 pregnant women consulting a maternity clinic in the Paris area. 1 metropolitan frenchwoman out of 9 and almost half of the immigrants were found to suffer from anaemia at term. A virtual absence of iron reserves (serum ferritin less than microgram/l) was found in 20% of the metropolitan women during the 3rd month of pregnancy, in 60% during the 6th month and in 75% during the 9th month. The figures were 60%, 100% and 90% respectively in the immigrant group. Considering the anaemia-related risks and the eventual repercussions of iron deficiency on a pregnancy, the health of the mother and the foetus, a systematic increase in iron as of the 2nd trimester of pregnancy is recommended.

Abstract
Thirty-two pregnant hypertensive patients were treated with oxprenolol administered in combination with dihydralazine as Trasipressol tablets. Before delivery, oxprenolol was demonstrable in the maternal plasma and the amniotic fluid. The free fraction of oxprenolol in the maternal serum (15% +/- 7.8; mean +/- s.d.; n = 25) was similar to that in normal serum. At the end of delivery, oxprenolol was found in both the maternal and umbilical plasma in most cases. Measurable, but low oxprenolol concentrations were present in the newborn plasma. After delivery, oxprenolol was demonstrable in the maternal plasma and breast milk. An infant weighing 3 kg and consuming 500 ml of breast milk per day would receive a maximum dose 60 times less than the normal daily dose for a hypertensive adult (4 mg/kg).

Abstract
Arterial blood gases (pH, pO2, p CO2) were studied in 100 patients with documented pulmonary embolism (Group A), confirmed by pulmonary angiography (n = 51) or scintigraphy ( n = 49). The pO2 ranged from 32 to 97 mm Hg (average 60,5 +/- 13 mm Hg). Hypoxaemia was found in 97 cases and would therefore seem to be a reliable sign of pulmonary embolism. In the three cases in which it was absent, the embolism was small. Hypoxaemia was associated with hypocapnia and alkalosis in 91 cases. However, hypoxaemia was not a specific finding; it was also present in 49 patients with suspected pulmonary embolism (Group B) in whom the diagnosis was excluded by pulmonary angiography or scintigraphy. A previous history of cardiovascular disease was found in 37 patients (76%) in this group: of the 12 remaining patients, 6 were heavy smokers and 4 were significantly obese. No correlation was found between the degree of hypoxaemia and the extent of amputation of the vascular bed on pulmonary angiography or scintigraphy. Nevertheless, a pO2 of under 50 mm Hg was always associated with a severe embolism with amputation of over 40% of the pulmonary vascular bed. A significant correlation was found between the severity of hypoxaemia and the degree of cyanosis (p less than 0,05) and ECG changes (p less than 0,01). The average pO2 was 59 +/- 12 mm Hg in patients with cardiovascular disease ( n = 21) and 55 +/- 11 mm Hg with known pulmonary disease ( n = 6). A higher average pO2 was found when these conditions were absent (61,5 +/- 13 mmHg). The difference was not statistically significant unless previous cardiac and pulmonary disease were associated (pO2 = 51 +/- 14 mm Hg, p less than 0,05).
