Abstract
To determine the factors associated with intrauterine insemination (IUI) miscarriages and reduce the IUI miscarriage rate, a retrospective study was performed by reviewing 31,933 IUI cycles from 2006 to 2018. The overall there were 14.50% clinical pregnancies, and 16.74% miscarriages. Logistic regression revealed the following three predictive variables: females aged ≥ 35 years (odds ratio [OR] = 2.131; p < 0.001), spontaneous miscarriage history (OR = 1.513; p = 0.005), and ovarian stimulation schemes such as clomiphene citrate (CC) (OR = 1.459; p = 0.003). The natural cycle led to a lower miscarriage rate for patients without spontaneous miscarriage history both for those over 35 years old (OR = 0.402; p = 0.034) and for those under 35 years old (OR = 0.806; p = 0.017). Gonadotropin (Gn) showed the lowest miscarriage rate for patients without abortion history, though no significant differences were found. Patients under 35 with a history of miscarriage were protected from miscarriage by using CC and Gn together (OR = 0.516; p = 0.032). No significant differences were found between various ovarian protocols when patients with abortion history were aged ≥ 35 years (p = 0.606). CC + Gn showed the lowest miscarriage rate. In conclusion, the natural cycle could be suggested for infertility couples to minimize abortion risk. When ovarian induction is required, CC + Gn had the lowest miscarriage rate for women with a history of spontaneous miscarriage while Gn is more successful for individuals without such a history.

Abstract
PURPOSE To investigate the effect of the cumulative exposure to estradiol (E(2)) during the follicular phase on IVF outcome. METHODS Patients were stimulated with recombinant FSH after GnRH agonist suppression and had a day 3-embryo transfer. Estrogen exposure was determined as the area under the curve (AUC) for serum E(2) levels measured from the first day of stimulation through the day after hCG administration. RESULTS E(2) AUC thresholds for 10th and 90th percentiles were 4704 pg/ml and 16338 pg/ml, respectively. The pregnancy and implantation rates were highest in the 10th-90th percentile group, and were statistically higher in this group than in the >90th percentile group (54.6% vs. 33.3% and 24.8% and 12.9%, respectively, for pregnancy and implantation rates, P < 0.05). Recovered mature oocytes, fertilization, and number and mean score of transferred embryos were similar. CONCLUSIONS High cumulative E(2) exposure during the follicular phase of IVF cycles has detrimental effects on implantation.

Abstract
OBJECTIVE To determine the maternal serum concentrations of inhibin, E2, P, and hCG in early pregnancies arising from IVF and ET or GIFT and to assess the value of these hormone measurements in determining outcome of pregnancy. DESIGN Serum immunoactive inhibin, E2, P, and hCG levels were measured in the first trimester of pregnancies after IVF-ET and GIFT procedures. SETTING In vitro fertilization and ET or GIFT was undertaken at Monash IVF, Melbourne, Victoria, Australia. PATIENTS At least two blood samples were collected from 117 women between 4 and 11 weeks of gestation. MAIN OUTCOME MEASURES The hormone concentrations in the IVF-ET and GIFT pregnancies were compared with those in pregnancies and related to outcome of pregnancy. RESULTS Serum inhibin levels in singleton pregnancies were significantly higher than in comparable normal pregnancies. In contrast to normal conceptions in which inhibin concentrations rose to peak at 11 weeks, the levels found in IVF-ET and GIFT singleton pregnancies were high at 5 weeks' gestation and declined subsequently. In twin pregnancies, the inhibin levels were significantly greater than those in singleton pregnancies. In biochemical pregnancies diagnosed by increasing hCG concentrations in the absence of an embryonic sac, inhibin levels were significantly lower than those found in singleton pregnancy, as were E2, P, and hCG levels. In anembryonic pregnancies, diagnosed by the confirmation of an intrauterine gestation sac with no evidence of a fetal complex, inhibin concentrations were highest at week 4 and declined, being significantly lower at all stages of gestation. In ectopic pregnancy, serum inhibin levels were lower at all stages of gestation, whereas E2 concentrations were not lower until 6 weeks and P levels until week 5. Serum hCG levels were significantly lower at all stages of gestation. In women with spontaneous abortions, inhibin levels were lower than singleton pregnancies at 7 weeks. CONCLUSIONS Serum inhibin concentrations are elevated in pregnancies arising from ovarian hyperstimulation in the first trimester when compared with those in normal pregnancy, probably as a result of the presence of multiple corpora lutea resulting from ovarian hyperstimulation. Serum inhibin, E2, P, and hCG are useful markers of abnormal pregnancy outcome.

Abstract
Serum estradiol, progesterone and luteinizing hormone (LH) levels of 16 pregnant and 58 non-pregnant stimulated in vitro fertilization-embryo transfer (IVF-ET) or gamete intrafallopian transfer (GIFT) cycles have been compared with regard to their predictive value for achievement of pregnancy. Serum estradiol and progesterone pattern of the pregnant and non-pregnant group did not show any significant difference. Around the time of ovulation induction by human chorionic gonadotropin (hCG) the serum LH values proved to be higher in the non-pregnant group than in the pregnant one. In spite of having a permissive function, preovulatory serum estradiol and progesterone seem not to have a predictive value with regard to pregnancy. Elevated preovulatory serum LH is detrimental for pregnancy, therefore the measurement of serum LH beyond hCG administration also, and the cancellation of cycles with high serum LH levels shortly before oocyte retrieval is recommended.

Abstract
STUDY OBJECTIVE To determine if gonadotropin-releasing hormone agonist (GnRH-a) and gonadotropin therapy could improve folliculogenesis and pregnancy rates (PRs) in women with a previously satisfactory response to clomiphene citrate and human menopausal gonadotropin (hMG). DESIGN Randomized prospective study. SETTING Assisted reproduction clinic. PATIENTS One hundred fifty-seven women were randomized to receive either hMG alone or the GnRH-a buserelin acetate 600 microgram/d or buserelin acetate 1,200 microgram/d plus hMG. RESULTS Compared with hMG alone, pretreatment with buserelin acetate significantly increased the PR per cycle started by preventing a premature luteinizing hormone rise and thereby reducing the number of abandoned cycles. There was, however, no difference between the number of follicles aspirated, oocytes obtained, or fertilization rates between groups. Furthermore, agonist therapy significantly increased both the dose of hMG required and the duration of stimulation. CONCLUSION The routine use of GnRH-a in in vitro fertilization programs must be questioned.

Abstract
The use of gonadotropin-releasing hormone agonists as adjuncts to ovulation induction for in vitro fertilization (IVF) has resulted in increases in oocyte recovery rates. Along with increased oocyte number, greatly increased estradiol (E2) levels have been found. We sought to determine the clinical effect of very high E2 levels on the outcome of IVF cycles. Estradiol levels were measured in 141 patients undergoing controlled ovarian hyperstimulation with leuprolide acetate and human menopausal gonadotropin for IVF. Whereas the number of oocytes recovered and fertilized and the number of embryos available for cryopreservation were directly proportional to the E2 level, the fertilization rate and embryo cleavage rates were unrelated to the E2 level. When the patients were grouped in thirds according to E2 levels, pregnancy rate (PR) was highest in the patients with the highest E2 levels (E2 greater than 2,777 pg/mL, PR = 37%). One mild, one moderate, and one severe case of ovarian hyperstimulation syndrome occurred in patients with E2 greater than or equal to 3,000 pg/mL (n = 21), but in general, high E2 levels were attained with few complications. We conclude that high E2 levels are not detrimental to the pregnancy outcome of IVF. Our experience further suggests that cycles with E2 levels of less than or equal to 5,000 pg/mL need not be canceled and can proceed to oocyte recovery and embryo transfer.

Abstract
To identify the time when relaxin can first be detected in peripheral sera after in-vitro fertilization (IVF) and embryo transfer, blood samples were collected from 20 women up to 14 days after oocyte retrieval. Sixteen women did not become pregnant and in eight of them relaxin (but not beta-human chorionic gonadotrophin, beta-hCG) was measurable for the first time at days 6 to 12. Concentrations of other hormones measured were also different in these eight women compared with the remaining eight non-pregnant women; their serum concentrations of 17 alpha-OH progesterone, progesterone and oestradiol were higher but concentrations of luteinizing hormone and follicle-stimulating hormone were lower. Three women became pregnant; relaxin and beta-hCG were first detected on the same day (10 to 12). The remaining woman had increased beta-hCG levels but did not develop a clinical pregnancy. Measurement of serum relaxin during IVF cycles may allow assessment of corpora luteal function before its identification by levels of steroid hormones.

Abstract
To examine the secretion of oxytocin (OT) and progesterone (P) from a homogeneous population of cells during luteinization, we developed a serum-free culture technique for granulosa cells, obtained from individual preovulatory bovine follicles. Granulosa cells from earlier stages of the follicle development did not have the capability to secrete OT under the in vitro conditions used. For optimal stimulation of the cells the medium (a 1:1 mixture of Dulbecco's modified Eagle's medium and Ham's F-12) was supplemented with bovine serum albumin (BSA) and insulin. OT was detectable from day 1 of culture reaching a maximum level between days 2 and 4 and then declined towards day 5. In the absence of insulin OT declined from day 1 onwards and was undetectable from day 4. When cells were cocultured with theca tissue or theca-conditioned medium (TCM), there was an enhancement in OT secretion, but not in P secretion. Other tissues including liver, kidney, aorta, muscle and adrenal incubated with the cells induced a similar increase in OT production. In the presence of insulin progesterone secretion was increased and was correlated with OT production, but did not show a consistent pattern among follicles. We conclude that (a) culture of granulosa cells from an individual follicle in a serum-free medium can be used to study the secretion of OT and P from bovine granulosa cells, (b) insulin is essential for the optimal production of OT and P by these cells, and (c) the addition of theca or other tissues enhanced OT secretion by a mechanism not understood.

Abstract
Endogenous-luteinizing hormone (LH) surges may complicate the management of in vitro fertilization cycles. To investigate the effects of LH surges after hormonal stimulation 53 IVF cycles were analyzed by assessing LH levels three times daily until egg collection. In 43% the LH rise started before the planned exogenous trigger for ovulation was given, in 11% the rise occurred simultaneously with and in 45% after the injection of human chorionic gonadotropin. Three main patterns of serum LH surges were identified: (A) low-LH tonus with straight increase to maximum; (B) low tonus with elevation before straight increase; (C) high tonus with large variations but no prominant peak. These patterns were not related to the follicular estradiol increase, luteal steroid concentrations or resulting pregnancy rates.

Abstract
Oocyte donation provides an option for achieving pregnancy in women lacking functioning gonads, or in whom IVF techniques have failed to harvest adequate oocytes, or those who do not wish to use their own gametes because of hereditary disease. In agonadal women, artificial menstrual cycles are required before proceeding to gamete donation. A fixed cyclical steroid replacement schedule of oestradiol (E2) valerate and progesterone (P4) pessaries was initially used, but the need for synchrony between donor and recipient cycles, and the narrow window for implantation limited the transfer of fresh embryos. Donor-recipient cycle asynchrony can be overcome by using frozen-thawed embryos, or by extending the follicular phase in the recipient to widen the transfer window. Twenty-two pregnancies have now been achieved by the Monash/Epworth group, resulting in the birth of 13 healthy infants. There were no statistically significant differences in pregnancy rates (per transfer) between transfers in natural cycles (14%, four pregnancies) and steroid replacement cycles (24%, 16 pregnancies). Five pregnancies (36%) were established in women treated with 2 mg of E2 daily 13-18 days before embryo transfer with P4 starting on the day of or the day following oocyte retrieval. E2 was continued for a median of 85 days (range 49-110) and P4 for a median of 86 days (range 49-133) after the supposed last menstrual period. All but one delivery was by caesarean section. There were no perinatal deaths and no ectopic pregnancies.

Abstract
Treatment with clomiphene citrate and human menopausal gonadotropin (HMG) is often used to induce folliculogenesis before in vitro fertilization, but not all women have an adequate response. It has been hypothesized that abnormally high levels of luteinizing hormone (LH) may contribute to the reduced folliculogenesis. We therefore performed a controlled, open trial in which treatment with buserelin, an agonist of luteinizing hormone-releasing hormone citrate and HMG in 44 consecutive women in whom no oocytes or only one had been produced by standard treatment with clomiphene and HMG. Twenty-nine women received buserelin with HMG, and 15 received clomiphene citrate with HMG. The median number of oocytes per patient recovered from those who received buserelin with HMG was 4 (range, 0 to 19), as compared with 0 (range, 0 to 5) in those who received clomiphene citrate with HMG. The fertilization rates of oocytes recovered from both groups of patients were similar (75.8 percent and 76.5 percent, respectively). Fifty-four percent of patients given buserelin with HMG underwent triple-embryo transfer, as compared with 13 percent of those given clomiphene citrate with HMG. Pregnancy (n = 3) occurred only among the patients receiving buserelin with HMG. In the buserelin-HMG group, significantly fewer oocytes were recovered from patients with occult ovarian failure (infertility and elevated follicular-phase levels of follicle-stimulating hormone, with regular menses) (median, 1; range, 0 to 4) than from those with other causes of infertility (median, 8; range, 0 to 19). Our data suggest that, except in women with occult ovarian failure, buserelin and HMG improve embryologic and clinical outcomes in patients with previously unsatisfactory stimulation of the ovaries for in vitro fertilization.

Abstract
Multiple factors influence the outcome of in vitro fertilization and embryo transfer (IVF-ET). This prospective study was designed to assess their relative importance, in order to improve prognostic ability and treatment success. Prior to IVF-ET, couples were divided into "good" (GP) and "poor" (PP) prognosis groups according to female age, semen quality, previous response to stimulation, and embryo quality. The data obtained from 716 consecutive treatment cycles then were evaluated using univariate statistics and logistic regression, a technique designed to assess the relative contribution of significant factors. The pregnancy rate per GP cycle was 14.7%, compared with 5.4% per PP cycle (chi 1(2) = 12.7, P less than 0.001). The most important prognostic factors were female age, the pregnancy rate showing a linear decline after the age of 25, and previous failed fertilization due to abnormal sperm. The rate of pregnancy also declined after 14 or more follicles were aspirated and/or nine oocytes were retrieved. A formula for the probability of pregnancy, derived from the logistic regression, provides patients with a more accurate prognosis before treatment.

Abstract
Two hundred twenty consecutive in vitro fertilization (IVF) conception cycles were studied prospectively in order to examine the predictive value of serum human chorionic gonadotropin beta-subunit (beta-hCG), estradiol (E2), and progesterone (P) in predicting pregnancy outcome between 2 and 4 weeks after oocyte collection. To examine the predictive value of each hormone in predicting clinical pregnancy outcome, each patient's result at each week was assigned a scoring system based on the 25th percentile value of the concentration of beta-hCG, E2, and P in ongoing singleton IVF pregnancies for each week of the study. All but one ectopic pregnancies had scores of 0 or 1 points between 2 and 4 weeks after oocyte collection. The scores in successful pregnancies were significantly higher than in unsuccessful pregnancies 2 weeks after oocyte collection. Ninety percent of women scoring 3 points 2 weeks after oocyte collection had ongoing IVF pregnancies. The authors conclude that determination of serum beta-hCG, E2, and P concentrations between 2 and 4 weeks after oocyte collection provides clinically useful information not only in the prediction of ectopic IVF pregnancy, but also, conversely, in the identification of IVF pregnancies that are destined to be ongoing.

Abstract
Treatment with nafarelin, a gonadotropin-releasing hormone agonist, reversibly inhibits ovarian function and induces hypoestrogenemia. To determine the efficacy of such hormonal manipulation in the treatment of endometriosis, we randomly assigned 213 patients with laparoscopically confirmed endometriosis to receive, for six months, either nafarelin by nasal spray (400 or 800 micrograms per day) or oral danazol (800 mg per day). Placebo nasal spray and placebo tablets were used to double blind the study. Pretreatment and post-treatment laparoscopies were compared by means of the American Fertility Society's scoring system. More than 80 percent of the patients in each treatment group had a reduction in the extent of disease as assessed by laparoscopy. The mean laparoscopic scores decreased from 21.9 to 12.6 with 800 micrograms of nafarelin, from 20.4 to 11.7 with 400 micrograms of nafarelin, and from 18.4 to 10.5 with danazol (P = 0.0001 within each group; there were no statistically significant differences between the groups). The percentage of women with severely painful symptoms of endometriosis decreased from about 40 percent to 5 to 10 percent, whereas the percentage with no or minimal discomfort rose from 25 to 70 percent. Of the 149 patients who tried to become pregnant, 58 (39 percent) succeeded after the completion of treatment; similar rates of pregnancy applied to the three treatment groups. Danazol use decreased high-density lipoprotein levels and increased low-density lipoprotein levels. These changes were not observed in nafarelin users, but a higher percentage of them reported hot flashes and decreased libido. We conclude that nafarelin is an effective agent for treating endometriosis and has few side effects other than hypoestrogenism.

Abstract
A study was conducted aimed at establishing a range of plasma concentrations of the beta subunit of human chorionic gonadotrophin that might predict ectopic pregnancy after in vitro fertilisation and embryo transfer. From May 1984 to February 1986, 161 consecutive pregnancies at the Monash University in vitro fertilisation unit were analysed by determining plasma beta human chorionic gonadotrophin concentrations between two and 10 weeks after oocyte collection. Eighty eight ongoing singleton pregnancies, 25 multiple pregnancies, 27 first trimester spontaneous abortions, 12 anembryonic pregnancies, and nine ectopic pregnancies resulted from these conception cycles. When compared with values for ongoing singleton pregnancies two weeks after oocyte collection plasma beta human chorionic gonadotrophin concentrations in ectopic pregnancies were significantly lower (p less than 0.05; Wilcoxon rank sum test). Two weeks after oocyte collection all plasma beta human chorionic gonadotrophin concentrations in the set of ectopic pregnancies were below 30.6 IU/l, which corresponded to the lower quartile (25th percentile) of beta human chorionic gonadotrophin concentrations in ongoing singleton pregnancies. The beta human chorionic gonadotrophin concentration corresponding to the lower quartile of ongoing singleton pregnancies at each week of gestation was used to derive the predictive value of various statistics in detecting ectopic pregnancy in patients after in vitro fertilisation. The sensitivity, specificity, predictive value of a positive result, predictive value of a negative result, and efficiency of a single plasma beta human chorionic gonadotrophin concentration in predicting ectopic pregnancy were 100%, 68.1%, 16.7%, 100%, and 70%, respectively, two weeks after oocyte collection. These results suggest that a single determination of the plasma beta human chorionic gonadotrophin concentration beginning 14 days after oocyte collection is clinically useful in predicting the outcome of pregnancy achieved by in vitro fertilisation. Ectopic pregnancy after in vitro fertilisation is more likely when beta human chorionic gonadotrophin concentration is below the lower quartile of values in ongoing singleton pregnancies achieved by the technique.

Abstract
The administration of ovarian stimulants to endocrine-normal women in IVF programmes gives the clinical endocrinologist an opportunity to modify natural folliculogenesis. Use of antioestrogens and/or gonadotrophins at the correct time has demonstrated that follicular atresia can be prevented and that multiple pregnancy-potent haploid ova can be obtained. Scrutiny of spontaneous menstrual cycles in patients who show unsatisfactory IVF responses has identified two new syndromes, premature follicle selection and occult ovarian failure, in these patients. The incidence of these disorders in fertile women is still unclear. Early results suggest that endocrine manipulations may overcome premature follicle selection and induce codominant folliculogenesis. Inhibin is a recently characterized ovarian protein which is increased in peripheral blood during IVF treatment. Results from IVF cycles suggest that plasma inhibin may be a new index of follicular function. Other potential indices of ovarian function, such as the luteal protein relaxin, may also develop from the application of basic research to IVF and advance knowledge of the human ovarian and menstrual cycles.
