Abstract
OBJECTIVE To compare two cancellation policies in controlled ovarian stimulation-intrauterine insemination (COS-IUI) cycles to lower the risk of multiple pregnancies (MP). DESIGN We performed a bicentric retrospective cohort study in two academic medical centers: Angers (group A) and Besançon (group B) University Hospitals. We included 7056 COS-IUI cycles between 2011 and 2019. In group A, cancellation strategy was based on an algorithm taking into account the woman's age, the serum estradiol level, and the number of follicles of 14 mm or greater on ovulation trigger day. In group B, cancellation strategy was case-by-case and physician-dependent, based on the woman's age, number of follicles of 15 mm or greater, and the previous number of failed COS-IUI cycles, without any predefined cut-off. Our main outcome measures were the MP rate (MPR) and the live-birth rate (LBR). RESULTS We included 884 clinical pregnancies (790 singletons, 86 twins, and 8 triplets) obtained from 6582 COS-IUI cycles. MPR was significantly lower in group A compared with group B (8.1% vs 13.3%, P = 0.01), but LBR were comparable (10.8% vs 11.8%, P = 0.19). Multivariate logistic regression found the following to be risk factors for MP: the "cancellation strategy" effect (adjusted odds ratio [aOR] 1.63, 95% confidence interval [CI] 1.02-2.60) and the number of follicles of 14 mm or greater (aOR 1.39, 95% CI 1.16-1.66). Cycle cancellation rate for excessive response was significantly lower in group A compared with group B (1.3% vs 2.4%, P < 0.001). CONCLUSIONS The use of an algorithm based on the woman's age, serum estradiol level and number of follicles of at least 14 mm on trigger day allows the MPR to be reduced without impacting the LBR.

Hum Reprod 2024; 39:335-345. [PMID: 38148021 DOI: 10.1093/humrep/dead259] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 11/20/2023] [Indexed: 12/28/2023] Open
Abstract
STUDY QUESTION What is the effect of small follicles on clinical pregnancy and multiple pregnancy rates in women undergoing IUI with ovarian stimulation (IUI-OS)? SUMMARY ANSWER The presence of ≥2 small follicles with a diameter of 10-12 or 12-14 mm was associated with an increased chance of clinical pregnancy and the presence of any 12-14 mm or larger follicles, but not smaller follicles, was statistically significantly associated with an increased risk for multiple pregnancy. WHAT IS KNOWN ALREADY IUI-OS is widely used as the first-line treatment for unexplained or mild male factor infertility. However, IUI is associated with the risk of multiple pregnancy. While the positive association between the number of follicles ≥14 mm and the chance of pregnancy and the risk of multiple pregnancy is known, the impact of smaller follicles is uncertain. STUDY DESIGN, SIZE, DURATION This was a retrospective cohort study that included women undergoing IUI cycles from January 2007 to May 2021 in one assisted reproduction center. PARTICIPANTS/MATERIALS, SETTING, METHODS We studied the impact of the number and size of follicles on trigger day on clinical pregnancy and multiple pregnancy rates. Generalized estimation equation regression models were used to compute unadjusted and adjusted odds ratios and 95% CI in all women and only women who achieved clinical pregnancy separately. The chance of clinical pregnancy and multiple pregnancy for different numbers of small follicles in cycles with one >18-mm follicle was calculated using marginal effects estimate. MAIN RESULTS AND THE ROLE OF CHANCE This cohort included 12 933 IUI cycles in 7504 women. The overall clinical pregnancy rate was 16.1% (2081/12 933), with a multiple pregnancy rate of 10.5% (218/2081). In the adjusted analysis, the chance of clinical pregnancy increased significantly with the increase in the number of follicles with the diameter of 14-16, 16-18, and 18-20 mm. As for 10-12 mm [adjusted odds ratio (aOR) 1.22, 95% CI 1.02-1.46] and 12-14 mm (aOR 1.29, 95% CI 1.07-1.56) follicles, only groups with ≥2 follicles of those sizes showed significantly increased chance of clinical pregnancy. In cycles that led to pregnancy, follicles with the diameter of 12-14 mm were associated with an increased risk of multiple pregnancy (aOR 1.73, 95% CI 1.19-2.53 for one such follicle; aOR 2.27, 95% CI 1.44-3.56 for ≥2 such follicles), while 10- to 12-mm follicles were not significantly associated with multiple pregnancy (aOR 1.18, 95% CI 0.72-1.95 for ≥2 such follicles). The associations of multiple pregnancy were similar when including all cycles. LIMITATIONS, REASONS FOR CAUTION This was a retrospective observational study from a single center. The records of follicle diameter in our center were of a 2-mm interval which limited our ability to analyze the size of follicle as a continuous variable. Also, the number of cycles with a high number of small follicles was still limited which impeded more detailed analysis on the ≥2 follicles subgroup. Similarly, the value of some parts of the marginal probability estimation for multiple pregnancy versus pregnancy according to size and number of follicles was also limited by the low sample size of certain combinations. WIDER IMPLICATIONS OF THE FINDINGS Follicles larger than 10 mm, especially those ≥12 mm, may need to be clearly recorded during transvaginal ultrasound surveillance and their potential effects on both pregnancy and multiple pregnancy can be discussed with couples undergoing IUI.

The role of peak serum estradiol level in the prevention of multiple pregnancies in gonadotropin stimulated intrauterine insemination cycles. Sci Rep 2022; 12:19554. [PMID: 36379965 PMCID: PMC9666543 DOI: 10.1038/s41598-022-23470-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Accepted: 11/01/2022] [Indexed: 11/16/2022] Open
Abstract
The objective was to assess whether the measurement of serum estradiol (E2) level on trigger day in controlled ovarian stimulation with intrauterine insemination (COS-IUI) cycles helps lower the multiple pregnancy (MP) rate. We performed a unicentric observational study. We included all patients who underwent COS-IUI and had a subsequent clinical pregnancy (CP) between 2011 and 2019. Our main outcome measure was the area under Receiver-Operating Characteristic (ROC) curve. We included 455 clinical pregnancies (CP) obtained from 3387 COS-IUI cycles: 418 singletons, 35 twins, and 2 triplets. The CP, MP, and live birth rates were respectively 13.4%, 8.1% and 10.8%. The area under ROC curve for peak serum E2 was 0.60 (0.52-0.69). The mean E2 level was comparable between singletons and MP (260.1 ± 156.1 pg/mL vs. 293.0 ± 133.4 pg/mL, p = 0.21, respectively). Univariate and multivariate logistic regression analysis showed that E2 level was not predictive of MP rate (aOR: 1.13 (0.93-1.37) and 1.06 (0.85-1.32), respectively). Our study shows that, when strict cancelation criteria based on the woman's age and follicular response on ultrasound are applied, the measurement of peak serum E2 levels does not help reduce the risk of MP in COS-IUI cycles.

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.

Abstract
As post-transplant survival improves, many heart transplant (HT) recipients are of, or are surviving to, childbearing age. Solid-organ transplant recipients who become pregnant should be managed by a multidisciplinary cardio-obstetrics team, including specialists in maternal and fetal medicine, cardiology and transplant medicine, as well as anesthesia, neonatology, psychology, genetics, and social services. With careful patient selection, pregnancy after HT can been managed safely. The purpose of this comprehensive review was to summarize the current evidence and recommendations surrounding preconception counseling, medical management and surveillance, maternal outcomes, breastfeeding, and remaining gaps in knowledge.

Abstract
RESEARCH QUESTION Can predictors of twin and high-order multiple pregnancy among women with multiple cycles of ovarian stimulation intrauterine insemination (IUI) be identified? DESIGN Retrospective cohort study of IUI cycles carried out between January 2014 and December 2015 in a private clinic in Spain. The 4879 women and 6552 cycles analysed in this study include single IUI with ovarian stimulation using recombinant FSH. RESULTS Number of follicles and follicle size were the only factors with a significant effect (P < 0.001) on the likelihood of achieving a twin or multifetal pregnancy. Follicles 12 mm or wider greatly increase the chances of achieving a twin or multifetal pregnancy. A total of 73 out of 127 (57.5%) twin pregnancies occurred in cycles with at least one additional follicle measuring 12 mm or wider, and 102 out of 127 twin pregnancies (80.3%) occurred in cycles with at least one additional follicle measuring 14 mm or wider. Cancellation criteria should consider the presence of follicles 12 mm or wider. CONCLUSION Follicles measuring 12 mm or wider increase the risk of having a twin or a high-order multiple pregnancy rate. These data may help clinicians balance decision-making between cancelling and performing the cycle within an IUI procedure.

Abstract
Background Multiple pregnancies are an important complication of assisted reproductive technology (ART). The present study aims to indentify the risk factors for multiple pregnancies independent of the number of transferred embryos. MATERIALS AND METHODS This retrospective study reviewed the medical records of patients who underwent intracytoplasmic sperm injection (ICSI) cycles in Royan Institute between October 2011 and January 2012. We entered 12 factors that affected the number of gestational sacs into the poisson regression (PR) model. Factors were obtained from two study populations-cycles with double embryo transfer (DET) and cycles that transferred three embryos (TET). We sought to determine the factors that influenced the number of gestational sacs. These factors were entered into multivariable logistic regression (MLR) to identify risk factors for multiple pregnancies. RESULTS A total of 1000 patients referred to Royan Institute for ART during the study period. We included 606 eligible patients in this study. PR analysis demonstrated that the quality of transferred embryos and woman's age had a significant effect on the number of observed sacs in patients who underwent ICSI with DET. There was no significant predictive variable for multiple pregnancies according to MLR analysis. Our findings demonstrated that both regression models (PR and MLR) had the same outputs. A significant relation existed between age and fertilization rate with multiple pregnancies in patients who underwent ICSI with TET. CONCLUSION Single embryo transfer (SET) should be considered with the remaining embryos cryopreserved to prevent multiple pregnancies in women younger than 35 years of age who undergo ICSI cycles with high fertilization rates and good or excellent quality embryos. However, further prospective studies are necessary to evaluate whether SET in women with these risk factors can significantly decrease multiple pregnancies and improve cycle outcomes.

Abstract
PURPOSE To evaluate the efficacy of minimal stimulation using discretely administered gonadotropin combined with clomiphene citrate (CC) or letrozole (LTZ) for intrauterine insemination (IUI) cycles. MATERIALS AND METHODS Total 257 IUI cycles from 158 infertile couples were assessed. A CC dose of 100 mg/day (n=126 cycles) or a LTZ dose of 5 mg/day (n=131 cycles) was administered on days 3-5 of the menstrual cycle for 5 days. Each group received human menopausal gonadotropin at a dose of 150 IU by two or three alternative day: CC combined with alternate-day regimen for 2 or 3 days (CC+300, n=37; CC+450, n=89) and LTZ combined with alternate-day regimen for 2 or 3 days (LTZ+300, n=36; LTZ+450, n=95). RESULTS The clinical pregnancy rate was comparable between the CC and LTZ groups (18.3% vs. 13.0%, p=0.243). The clinical pregnancy rate also showed no significant difference among the 4 groups (21.6% vs. 16.9% vs. 11.1% vs. 12.6%, p=0.507). The multiple pregnancy rate was significantly higher in LTZ compared to CC group (37.5% vs. 8.7%, p=0.028) and in the LTZ+450 compared to CC+450 group (50% vs. 13.3%, p=0.038). Overall, there were 15 cases of ovarian hyperstimulation syndrome (OHSS), with the prevalence being significantly lower in the LTZ compared to CC group (1.5% vs. 10.3%, p=0.003). OHSS was more prevalent in the CC+450 compared to the LTZ+450 group (12.4% vs. 1.1%, p=0.002). CONCLUSION Our findings suggest that minimal stimulation using two alternate-day gonadotropin with LTZ decreases the development of OHSS and multiple pregnancies, while maintaining comparable pregnancy rates in IUI cycles.

Abstract
Infertility outcomes can be influenced by many factors. Although a number of treatments are offered, deciding which one to use first is a controversial topic. Although IVF may have superior efficacy in achieving a live birth with a reasonable safety profile, the availability of cheaper and less invasive treatments preclude its absolute use. For this reason, certain patient groups with 'good-prognosis' infertility are traditionally treated with less invasive treatments first. 'Good-prognosis' infertility may include unexplained infertility, mild male factor infertility, stage I or II endometriosis, unilateral tubal blockage and diminished ovarian reserve. Here, evidence behind the use of IVF as a first-line treatment is compared with its use as a last-resort option in women with 'good-prognosis' infertility.

Abstract
Synchronization of oocyte maturation in vitro has been shown to produce higher in vitro fertilization (IVF) rates than those observed in oocytes matured in vitro without synchronization. However, the increased IVF rates never exceeded those observed in oocytes matured in vivo without synchronization. This study was therefore designed to define the effect of in vivo synchronization of oocyte maturation on IVF rates. Mice were superovulated and orally treated with 7.5 mg cilostazol (CLZ), a phosphodiesterase 3A (PDE3A) inhibitor, to induce ovulation of immature oocytes at different stages depending on frequency and time of administration of CLZ. Mice treated with CLZ ovulated germinal vesicle (GV) or metaphase I (MI) oocytes that underwent maturation in vitro or in vivo (i.e. in the oviduct) followed by IVF. Superovulated control mice ovulated mature oocytes that underwent IVF directly upon collection. Ovulated MI oocytes matured in vitro or in vivo had similar maturation rates but significantly higher IVF rates, 2-4 cell embryos, than those observed in control oocytes. Ovulated GV oocytes matured in vitro showed similar maturation rates but significantly higher IVF rates than those observed in control oocytes. However, ovulated GV oocytes matured in vivo had significantly lower IVF rates than those noted in control oocytes. It is concluded that CLZ is able to synchronize oocyte maturation and improve IVF rates in superovulated mice. CLZ may be capable of showing similar effects in humans, especially since temporal arrest of human oocyte maturation with other PDE3A inhibitors in vitro was found to improve oocyte competence level. The capability of a clinically approved PDE3A inhibitor to improve oocyte fertilization rates in mice at doses extrapolated from human therapeutic doses suggests the potential scenario of the inclusion of CLZ in superovulation programs. This may improve IVF outcomes in infertile patients.

Abstract
OBJECTIVE Assisted human reproduction has been associated with increased rates of multiple births. Data suggest that twins and higher order multiple pregnancies are at risk for pre- and postnatal health complications that contribute to stress on both the family and the Canadian health care system. No published Canadian data estimate the contribution of assisted human reproduction to multiple birth rates. This study was designed to determine the contributions of age and assisted human reproduction to multiple birth rates in Canada. METHODS We performed analyses of existing Canadian databases, using a mathematical model from the Centers for Disease Control and Prevention. More specifically, data from the Canadian Vital Statistics: Births and Stillbirths database were combined with data from the Canadian Assisted Reproductive Technologies Register collected by the Canadian Fertility and Andrology Society. Datasets were standardized to age distributions of mothers in 1978. RESULTS RESULTS suggest that in vitro fertilization, ovulation induction, and age each contribute more to the rates of triplets than to twins. As expected, the contribution of natural factors was higher to twins than to triplets. CONCLUSION These are the first Canadian data analyzed to separate and measure the contributions of age and assisted reproductive technologies to multiple birth rates. Our findings are important for guiding physician and patient education and informing the development of treatment protocols that will result in lower-risk pregnancies and improved long-term health for women and their offspring.

Comparison of different starting gonadotropin doses (50, 75 and 100 IU daily) for ovulation induction combined with intrauterine insemination. Arch Gynecol Obstet 2012; 286:1055-9.

Abstract
Purpose To prevent multiple pregnancies the goal of ovulation induction by gonadotropins is to achieve only mono-follicular development. The most important issue is therefore to determine the starting dose. The aim of this study is to compare three different starting doses of follitropin beta to assess the lowest effective dose. Methods We evaluated 92 cycles with ovarian stimulation for patients with unexplained infertility, anovulatory disorder or mild male factor. We prospectively divided patients into 50, 75 and 100 IU groups based on patients’ response to clomiphene citrate treatment. Results We performed 87 intrauterine inseminations (95 % of cycles with ovulation induction). Five cycles were cancelled. We achieved 15 pregnancies; total pregnancy rate was 18 %. Pregnancy rate was 22, 10 and 28 % in 50, 75 and 100 IU follitropin beta groups. The average number of follicles was 2.0 ± 0.8, 2.2 ± 1.1 and 2.5 ± 1.8 (ns), total dose of gonadotropins (IU) 483 ± 192, 600 ± 151 and 830 ± 268 (p < 0.001), respectively. We observed one case of twins in 75 and 100 IU treatment group, as well (25 % risk). Conclusions This study suggests that based on the dose which was chosen according to clomiphene citrate response, all treatment regimes were effective for ovulation induction. 50 IU of follitropin beta daily is the appropriate starting dose to support ovulation for clomiphene citrate-sensitive women. The disadvantage may be an increased risk of cycle cancellation due to low ovarian response. Daily doses 75 or 100 IU of rFSH increase total consumption of gonadotropins.

Abstract
OBJECTIVE To report and evaluate the performance and utility of an approach to predicting IVF-double embryo transfer (DET) multiple birth risks that is evidence-based, clinic-specific, and considers each patient's clinical profile. DESIGN Retrospective prediction modeling. SETTING An outpatient university-affiliated IVF clinic. PATIENT(S) We used boosted tree methods to analyze 2,413 independent IVF-DET treatment cycles that resulted in live births. The IVF cycles were retrieved from a database that comprised more than 33,000 IVF cycles. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) The performance of this prediction model, MBP-BIVF, was validated by an independent data set, to evaluate predictive power, discrimination, dynamic range, and reclassification. RESULT(S) Multiple birth probabilities ranging from 11.8% to 54.8% were predicted by the model and were significantly different from control predictions in more than half of the patients. The prediction model showed an improvement of 146% in predictive power and 16.0% in discrimination over control. The population standard error was 1.8%. CONCLUSION(S) We showed that IVF patients have inherently different risks of multiple birth, even when DET is specified, and this risk can be predicted before ET. The use of clinic-specific prediction models provides an evidence-based and personalized method to counsel patients.

Abstract
To compare cumulative pregnancy and live birth rates of single embryo transfer (SET) vs. double embryo transfer (DET) in women <35 years old with good-quality embryos, we designed an observational prospective study carried out between October 2002 and December 2006. Patients who accepted SET were compared with those who decided DET. A total of 628 couples who underwent embryo transfers met the criteria for SET: 52% accepted it, while 47.8% asked for DET. Implantation rate was higher in SET, 46.6% (p < 0.05), whereas pregnancy rate (PR) per transfer was higher in DET, 38.3% (p < 0.05). Twin PR in DET was 26.4% compared with 0.7% in SET (p < 0.05). SET group performed 278 frozen embryo transfer and DET 128. The mean of embryos transferred was the same, resulting in similar pregnancy and twin PR (SET: 24.8% and 21.7% vs. DET: 25.0% and 28.1%). Cumulative PR was 66.2% in SET and 69.7% in DET, not showing significant differences (NS). Likewise, cumulative live birth rates did not show differences. Cumulative twin PR in SET was 7.2% and in DET 26.6%, (p < 0.05). Cumulative PR over time leveled at 15-18 months follow-up in both groups. In Conclusion, in order to reduce twins we support the promotion of SET.

Abstract
Ovarian stimulation and intrauterine insemination (OS/IUI), a mainstay of current infertility therapy and a common antecedent to IVF, is a significant driver of the multiple births epidemic. Redress of this challenge, now marking its quarter centennial, will require a rethinking of current practice patterns. Herein we explore prospects for prevention, mitigation, and eventual resolution. We conclude that the multiple births attributable to OS/IUI may not be entirely preventable but that the outlook for their mitigation is promising, if in need of solidification. Specifically, we observe that low-dose (≤ 75 IU) gondotropin, clomiphene, and especially off-label letrozole regimens outperform high-dose (≥ 150 IU) gonadotropin counterparts in the gestational plurality category while maintaining comparable per-cycle pregnancy rates. Accordingly we recommend that, subject to appropriate exceptions, high-dose gonadotropin regimens be used sparingly and that whenever possible they be replaced with emerging alternatives. Finally, we posit that OS/IUI is not likely to be superseded by IVF absent further commoditization and thus greater affordability.

Abstract
BACKGROUND Based on a presumed negative impact of overweight and obesity on reproductive capacity and pregnancy outcome, some national guidelines and clinicians have argued that there should be an upper limit for a woman's BMI to access assisted reproductive technologies (ART). However, evidence on the risk of complications or expected success rate of ART in obese women is scarce. We therefore performed a systematic review on the subject. METHODS We searched the literature for studies reporting on complications or success rates in overweight and obese women undergoing ART. Articles were scored on methodological quality. We calculated pooled odds ratios (ORs) to express the association between overweight and obesity on the one hand, and complications and success rates of ART on the other hand. We only pooled results if data were available per woman instead of per cycle or embryo transfer. RESULTS We detected 14 studies that reported on the association between overweight and complications during or after ART, of which 6 reported on ovarian hyperstimulation syndrome (OHSS), 7 on multiple pregnancies and 6 on ectopic pregnancies. None of the individual studies found a positive association between overweight and ART complications. The pooled ORs for overweight versus normal weight for OHSS, multiple pregnancy and ectopic pregnancy were 1.0 [95% confidence interval (CI) 0.77-1.3], 0.97 (95% CI 0.91-1.04) and 0.96 (95% CI 0.54-1.7), respectively. In 27 studies that reported on BMI and the success of ART, the pooled ORs for overweight versus normal weight on live birth, ongoing and clinical pregnancy following ART were OR 0.90 (95% CI 0.82-1.0), 1.01 (95% CI 0.75-1.4) and OR 0.94 (95% CI 0.69-1.3), respectively. CONCLUSIONS Data on complications following ART are scarce and therefore a registration system should be implemented in order to gain more insight into this subject. In the available literature, there is no evidence of overweight or obesity increasing the risk of complications following ART. Furthermore, they only marginally reduce the success rates. Based on the currently available data, overweight and obesity in itself should not be a reason to withhold ART.

Abstract
Ovulation induction (OI) or ovulation enhancement (OE) with gonadotrophins can be a reasonable treatment option for patients with a variety of infertility diagnoses. It must be used with extensive monitoring and management given the risk of multiple pregnancy,especially high-order multiples. This retrospective study evaluated per cycle outcomes of a large cohort of 1452 gonadotrophin OI/OE cycles at an academic infertility centre, and the efficacy of specific guidelines in limiting multiple pregnancy. The lowest possible gonadotrophin doses were used and cycle cancellation was recommended if more than three dominant follicles were present, and/or ifserum oestradiol was above 1500 pg/ml. Overall, pregnancy rate (PR) was 12% and live birth rate was 7.7%, with an increasing trend in younger patients (P = 0.0002 and <0.0001, respectively). Multiple clinical PR was 2.6% with 1.9% twins and 0.7% triplets and above.The birthweight of a singleton from a vanishing twin pregnancy (n = 8)was significantly lower than other singletons (2882 g versus 3250 g,P = 0.013). Reducing multiple pregnancies from OI/OE cycles remains an important and challenging goal. In this large cohort, high-order multiple clinical PR was limited to 0.7% per cycle by using specific management strategies while maintaining a reasonable PR.

Abstract
Multiple pregnancy is one of the greatest perinatal challenges facing clinicians today. In a society of rising expectations among fertility and maternity service users, the potential for adverse outcomes associated with multiple pregnancy is a source of concern. This article examines the impact of assisted conception on the incidence of multiple pregnancies and associated complications. It explores some of the reasons for the strong association between assisted reproductive technology and multiple pregnancies and suggests possible ways of addressing this continuing problem.

Abstract
INTRODUCTION Although ovulation induction is commonly used to treat infertility, few data are available concerning this treatment. Therefore, the aim of this prospective observational study was to describe medical practices and to identify predictive outcome factors of ovarian stimulation by recombinant FSH (r-hFSH), administrated with a self-injector pen. PATIENTS AND METHODS At the time of the prescription of ovarian stimulation followed by sexual intercourse (SI) or artificial insemination (HAI) with a normal husband sperm, 370 gynaecologists consecutively sent from January to November 2005, for a maximum of six patients (1398 patients in total), a form dealing with the assessment of infertility factors prior to stimulation (n=1340), then a monitoring form of the treated cycle (n=1227) and when a pregnancy was obtained, a follow-up form at 12 weeks of amenorrhea (n=254). Each patient had to complete an autoquestionnaire about the use of the pen (n=1044). RESULTS Seventy percent of the contributing gynaecologists had only a private practice. The mean age of patients was 31.9+/-4.8 years. Dealing with infertility exploration prior to stimulation, 9% did not have tubal assessment. Although it was the first stimulation attempt for 52% of cases, 91% of patients found the pen easy to manipulate. The mean duration of r-hFSH administration was 8.8+/-3.7 days and the mean daily dose was 75.4+/-29.4 IU. Ultrasound and hormonal monitoring was performed for 88% of patients. The cycle cancellation rate was 11%. The hCG administration was performed on cycle day 13+/-3. An HAI was programmed in 60% of patients and SI in 40%. The pregnancy rates for positive betahCG, ongoing and multiple pregnancies were, respectively, 22.7, 18 and 16% (twins 14%; 2% of triplets or more 2%). Three prognosis factors were independently related to ongoing pregnancy rate: age<35 years, previous pregnancy obtained by treatment and presence of ovulatory disorders. DISCUSSION AND CONCLUSION This observatory of ovarian stimulation out of FIV allowed to describe medical practices of gynaecologists: infertility assessment prior to ovarian stimulation, used FSH doses, ultrasound and hormonal monitoring, and it outlined three predictive factors of outcome: age, previous pregnancy obtained by treatment and presence of ovulatory disorders.

Abstract
Infertility treatments that include ovulation stimulation, both assisted reproductive technologies (ARTs) and non-ART ovulation stimulation, are associated with increased risks of multiple birth and concomitant sequelae and adverse outcomes, even among singletons. While a US surveillance system for ART-induced births is ongoing, no population-based tracking system exists for births resulting from non-ART treatments. The authors developed a multistage model to estimate the uncertain proportion of US infants born in 2005 who were conceived by using non-ART ovulation treatments. Using published surveillance data, they estimated proportions of US multiple births conceived naturally and by ART and assumed that the remainder were conceived with non-ART treatments. They used Bayesian meta-analyses to summarize published clinical studies on the multiple-gestation risk associated with non-ART ovulation treatments, applied a fetal survival factor, and used this multiple-birth risk estimate and their own estimate of the proportion of US multiple births attributable to non-ART ovulation stimulation to estimate the total (and, through subtraction, singleton) proportion of infants conceived with such treatments. On the basis of the model, the authors estimate that 4.6% of US infants born in 2005 (95% uncertainty range: 2.8%-7.1%) resulted from non-ART ovulation treatments. Notably, this figure is 4 times greater than the ART contribution.

Abstract
The objective of this prospective study was to identify predictors of ovarian response in ovulatory patients treated with low-dose recombinant FSH (rFSH), gonadotrophin-releasing hormone antagonist and intrauterine insemination (IUI), and to develop an rFSH dosage nomogram based on the findings. Patients (n = 159) were stimulated with a starting dose of 75 IU rFSH/day. Ten parameters were investigated as possible predictors of the number of mature follicles >or=15 mm: age, spontaneous cycle length, body weight, body mass index, smoking status, total ovarian volume, total number of antral follicles, total Doppler score of the ovarian stromal blood flow, baseline FSH and oestradiol. Simple and multiple linear regressions were used for the statistical analysis. Appropriate ovarian response was defined as two to three mature follicles. Body weight (P = 0.001) and the number of antral follicles (P = 0.004) were the strongest independent predictive factors of the number of mature follicles. In conclusion, body weight and antral follicle count may be used to achieve appropriate ovarian response for IUI in ovulatory patients. Based on this, a simple rFSH dosage nomogram was developed for individual ovarian stimulation prior to IUI.

Abstract
OBJECTIVE To review factors associated with high-order multiple births (HOMB) due to ovulation induction (OI) and the efficacy of strategies to reduce their occurrence. DESIGN Retrospective analysis of published studies of OI with intrauterine insemination (IUI) where patient and cycle characteristics were fully documented. RESULT(S) High-order multiple pregnancies (HOMP) were positively related to use of high doses of gonadotropin, number of 7-10 mm preovulatory follicles, and E(2), and inversely related to age and number of treatment cycles. Strategies successful in reducing HOMP include: use of clomiphene (CC) before gonadotropins, minimal gonadotropin doses, cancellation for more than three follicles >10-15 mm, and aspiration of excess follicles. Depending on the strategy used, 5%-20% of cycles may be canceled but HOMP rates can be less than 2% and pregnancy rates can average 10%-20% per cycle. Pregnancy rates per patient need not be reduced if low doses are continued for 4-6 cycles. CONCLUSION(S) High-order multiple pregnancies due to OI can be reduced to 2% or less by less aggressive stimulation without reducing overall chances of pregnancy for most patients.

Abstract
Solid organ transplantation can prolong the life of individuals with end-stage diseases that affect the kidney, liver, lung, heart, and pancreas. The improved survival of transplant recipients has led to increased attention on quality of life issues, including controlling fertility and having children. Perturbations of the hypothalamic-pituitary-ovarian axis in women with chronic renal failure or severe hepatic dysfunction result in anovulation and reduced fertility. Most often, fertility is restored with successful organ transplantation and good overall health. Although there are case reports of children born subsequent to assisted reproductive technologies (ART) in female transplant recipients, the approach to infertility in this population has not been described. Recognizing the unique medical, ethical, and psycho-social concerns involved in treating infertile female transplant recipients, reproductive endocrinologists must work with a multi-disciplinary team to ensure a successful pregnancy outcome without compromising graft function or maternal health. The primary goal of ART is a singleton pregnancy without complications, such as ovarian hyperstimulation syndrome, that pose greater risks in transplant recipients.

Abstract
OBJECTIVE To examine the effect of the 1998 Society for Assisted Reproductive Technology/American Society for Reproductive Medicine (SART/ASRM) Practice Committee recommendation to limit the number of embryos transferred on high order multiple births (HOMB) due to assisted reproduction technology (ART) and ovulation induction (OI) in the United States. SETTING None. DESIGN Analysis of U.S. natality files, and U.S. Centers for Disease Control and Prevention (CDC) and ASRM/SART registry reports. SETTING None. PATIENT(S) None. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Number and ratio of twin, triplet, and quadruplet or higher order (quadruplet/+) multiple births. Percentage of HOMB due to ART, OI, natural conception, and unexplained. RESULT(S) Between 1998 and 2003, the number of twin births (number of live-born infants in twin deliveries) in the United States increased 17%, and the number of HOMB was unchanged. Since 1998, total births due to ART increased 67%, twin births increased 65%, triplet births deceased 8%, and quadruplet/+ births decreased 35%. The ratio of twin, triplet, and quadruplet/+ births to total ART births decreased 2%, 45%, and 61% respectively. In 2003, the estimated percentages of multiple births due to ART and OI were twins 16% and 21%, triplets 45% and 37%, and quadruplets/+ 30% and 62%, respectively. CONCLUSION(S) Following publication of the SART/ASRM recommended limits on number of embryos transferred, the ratio of HOMB births to total ART births decreased substantially; however, U.S. HOMB did not decrease due to a 67% increase in total ART births and an increase in triplet births from OI.

Abstract
OBJECTIVES The goal of this study was to determine the relationship between the number of mature ovarian follicles and the (multiple) live birth rate after controlled ovarian hyperstimulation and intrauterine insemination. STUDY DESIGN A total of 2463 intrauterine insemination cycles performed during a natural cycle (n = 118), or after controlled ovarian hyperstimulation with either clomiphene citrate (n = 663) or with gonadotrophins (n = 1682) were reviewed to assess the impact of the type of stimulation and the number of follicles 14 mm or larger on the (multiple) live birth rate per cycle. RESULTS The live birth rate after intrauterine insemination was significantly higher (P = .02) after stimulation with gonadotrophins (13%) than after clomiphene cirate (8%) if only 1 follicle 14 mm or larger was present. If 2 or more follicles were present, there was no statistically significant difference between both stimulation methods. CONCLUSION Treatment of intrauterine insemination with gonadotrophin is effective with an acceptable (multiple) live birth rate when 1 or 2 follicles 14 mm or larger are present.

Abstract
OBJECTIVES To compare the administration of GnRH antagonist in gonadotropin intrauterine insemination (IUI) cycles with cycles where no intervention took place. DESIGN Meta-analysis of published prospective randomized trials. PATIENTS(S) Five hundred twenty-one patients who were administered a GnRH antagonist and 548 conservatively treated patients who served as control subjects were included in the meta-analysis. INTERVENTION(S) STUDY SELECTION Prospective trials were retrieved from Medline and Cochrane Library (last update October 2006). Random effect analysis was used in this meta-analysis. Two independent reviewers performed data extraction. MAIN OUTCOME MEASURE(S) Clinical pregnancy rates. RESULT(S) Six comparisons were retrieved including 1,069 patients. Higher pregnancy rates were found in the randomized controlled trials (odds ratio [OR] 1.56, 95% confidence interval [CI] 1.05-2.33) when a GnRH antagonist was added to a gonadotropin superovulated IUI protocol. Early published studies with smaller sample sizes showed stronger associations (OR 2.31, 95% CI 1.15-4.63) than later studies (OR 1.32, 95% CI 0.79-2.23). CONCLUSION(S) From the randomized controlled trials of this meta-analysis, it is clear that allowing for follicle growth and avoiding premature LH rise, increased pregnancy rates are observed with GnRH antagonist administration. A parallel trend for multiple pregnancy rates in the GnRH antagonist group was observed, although this did not reach statistical significance. The flexible regimen was widely used. This meta-analysis of early data might enhance further research in this direction.

Abstract
BACKGROUND Intra-uterine insemination (IUI) is one of the most frequently used fertility treatments for couples with male subfertility. Its use, especially when combined with ovarian hyperstimulation (OH) has been subject of discussion. Although the treatment itself is less invasive and expensive than others, its efficacy has not been proven. Furthermore, the adverse effects of OH such as ovarian hyperstimulation syndrome (OHSS ) and multiple pregnancy are a concern. OBJECTIVES The aim of this review was to determine whether for couples with male subfertility, IUI improves the live birth rates or ongoing pregnancy rates compared with timed intercourse (TI), with or without OH. SEARCH STRATEGY We searched the Cochrane Menstrual and Disorders Subfertility Group Trials Special Register, the Cochrane Central Register of Controlled Trials (the Cochrane Library, 2006, issue 3), MEDLINE (1966 to May 2006), EMBASE (1980 to May 2006), SCIsearch and the reference lists of articles. We hand searched abstracts of the American Society for Reproductive Medicine, the European Society for Human Reproduction and Embryology. Authors of identified articles were contacted for unpublished data. SELECTION CRITERIA Randomised controlled trials (RCT's) with at least one of the following comparisons were included: 1) IUI versus TI or expectant management both in natural cycles 2) IUI versus TI both in cycles with OH 3) IUI in natural cycles versus TI + OH 4) IUI + OH versus TI in natural cycles 5) IUI in natural cycles versus IUI + OH. Couples with abnormal sperm parameters only were included. DATA COLLECTION AND ANALYSIS Two co-reviewers independently performed quality assessment and data extraction. Where possible data were pooled, and a meta-analysis was performed. Sensitivity and subgroup analyses were carried out where possible and appropriate. MAIN RESULTS Three trials of parallel design, and five trials of cross-over design with pre-cross-over data were included in the meta-analysis. Three compared IUI with TI both in stimulated cycles. The remaining four of these studies compared IUI versus IUI + OH . Three studies reported on our main outcome of interest live birth rate per couple. For the comparison IUI versus TI both in natural cycles no evidence of difference between the probabilities of pregnancy rates per woman after IUI compared with TI was found (Peto OR 5.3, 95% CI 0.42 to 67). No statistically significant of difference between pregnancy rates (PR) per couple for IUI + OH versus IUI could be found (Peto OR 1.47, 95% CI 0.92 to 2.37). For the comparison IUI versus TI both in stimulated cycles there was no evidence of statistically significant difference in pregnancy rates per couple either (Peto OR 1.67, 95% CI 0.83 to 3.37). There were insufficient data available for adverse outcomes such as OHSS, multiple pregnancy, miscarriage rate and ectopic pregnancy to perform a statistical analysis. For the other two comparisons no RCT's were found which reported pregnancy rates per couple. A further 10 studies which included one of the comparisons of interests were found. Since these studies reported pregnancy rates per cycle only these data could not be included in the meta-analysis. AUTHORS' CONCLUSIONS There was insufficient evidence of effectiveness to recommend or advise against IUI with or without OH above TI, or vice versa. Large, high quality randomised controlled trials, comparing IUI with or without OH with pregnancy rate per couple as the main outcome of interest are lacking. There is a need for such trials since firm conclusions cannot be drawn yet.

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 determine whether including a GnRH antagonist in controlled ovarian stimulation-intrauterine insemination cycles would increase pregnancy rates. DESIGN Prospective randomized study. SETTING Private reproductive medicine clinic in Spain. PATIENT(S) Three hundred sixty-seven women with primary or secondary infertility. INTERVENTION(S) Patients were randomly assigned to controlled ovarian stimulation with recombinant FSH (75-150 IU/d) alone (controls, n = 183) or with recombinant FSH (75-150 IU/d) + the GnRH antagonist (0.25 mg/d), initiated when the recruited follicles were >or=16 mm (n = 184). A single insemination was performed, 36-38 hours after hCG (5,000 IU, IM), in both groups. MAIN OUTCOME MEASURE(S) Follicular recruitment, pregnancy rates. RESULT(S) Numbers of mature follicles (2.4 +/- 1.3 vs. 1.3 +/- 1.09) and clinical pregnancy rates (23% vs. 11%) were statistically significantly higher in patients who were treated with GnRH antagonist than in those who were in the control group. The pregnancy rate was only higher in the antagonist group if more than one follicle sized >or=18 mm was present on the day that the hCG was given. A similar number of twin pregnancies occurred in both groups: two in the antagonist group and three in the control group. The antagonist group also had one triplet gestation. CONCLUSION(S) Adding GnRH antagonist to controlled ovarian stimulation-intrauterine insemination cycles significantly increases pregnancy rates in multifollicular, but not monofollicular, cycles.

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
OBJECTIVES To compare the in vivo effectiveness of recombinant (r) hCG with urinary (u) hCG during controlled ovarian hyperstimulation and intrauterine insemination (COH-IUI) cycles. DESIGN Prospective controlled clinical study. SETTING Private IVF center. PATIENT(S) Two hundred eighty-four subjects undergoing COH-IUI cycles. INTERVENTIONS(S) Women were randomized into receiving r-hCG or u-hCG for final maturation and induction of ovulation. MAIN OUTCOME MEASURE(S) Clinical pregnancy rate and outcome of pregnancy. RESULT(S) Background characteristics were similar in the two groups studied except for a slight difference in the mean duration of infertility (3.0 vs. 2.3). There was no significant difference in the number of follicles > or =16 mm, mean peak E(2), or mean 1-week P levels between the two groups. The clinical pregnancy rate was 27.1% in the recombinant group compared with 28.5% in the urinary group. The outcome of pregnancy was similar in both groups. CONCLUSION(S) Recombinant hCG was found to be as effective as u-hCG in achieving pregnancy during COH-IUI cycles. This is in agreement with earlier studies on the effectiveness of r-hCG in IVF cycles.

Abstract
Aim: The aim of the present study was to identify the risk factors, their prognostic value on multiple pregnancies (MP) prediction and their thresholds in women undergoing controlled ovarian hyperstimulation (COH) with follicle stimulating hormone (FSH) and intrauterine insemination (IUI). Methods: A case-control study was carried out by identifying in our database all the pregnancies reached by donor and conjugal IUI (DIUI and CIUI, respectively), and compared cycle features, patients' characteristics and sperm analysis results between women achieving single pregnancy (SP) versus MP. The number of gestational sacs, follicular sizes and estradiol levels on the human chorionic gonadotropin (hCG) administration day, COH length and semen parameters were obtained from each cycle and compared. Student's t-tests for mean comparisons, receiver-operator curve (ROC) analysis to determine the predictive value of each parameter on MP achievement and multiple regression analysis to determine single parameter influence were carried out. Results: Women with MP in IUI stimulated cycles reached the adequate size of the dominant follicle (17 mm) significantly earlier than those achieving SP. Also, the mean follicles number, and estradiol levels on the hCG day were higher in the CIUI and DIUI MP group. Nevertheless, only ROC curve analysis revealed good prognostic value for estradiol and follicles higher than 17 mm. Multiple regression analysis confirmed these results. No feature of the basic sperm analysis, either in the ejaculate or in the prepared sample, was different or predictive of MP. When using donor sperm, different thresholds of follicle number, stimulation length and estradiol in the prediction of MP were noted, in comparison with CIUI. Conclusions: MP in stimulated IUI cycles are closely associated to stimulation length, number of developed follicles higher than 17 mm on the day of hCG administration and estradiol levels. Also, estradiol has a good predictive value over MP in IUI stimulated cycles. The establishment of clinical thresholds will certainly help in the management of these couples to avoid undesired multiple pregnancies by canceling cycles or converting them into in vitro fertilization procedures.

Abstract
The aim of this retrospective study was to assess the results of intrauterine insemination (IUI) in The Netherlands, using data from 2003 taken from hospital annual reports and reports from individual gynaecologists. By extrapolation, the total number of IUI cycles performed that year nationwide, and the related outcomes, was estimated. IUI was performed in 91 of the country's 101 hospitals. Of these, 58 (64%) registered their IUI results and performed 19,846 IUI cycles. The mean pregnancy rate per cycle was 9.0% and the ongoing pregnancy rate per cycle was 7.3%. Multiple pregnancies occurred in 9.5% of the ongoing pregnancies. Extrapolation of the data suggested that approximately 28,500 IUI cycles were performed, of which approximately 2000 resulted in an ongoing pregnancy. The number of multiple pregnancies following IUI was estimated to be 180 (9.0%). According to the national IVF registry, 9761 IVF cycles were started in 2003, resulting in 2,028 ongoing pregnancies (20.8% per cycle) and 439 twin pregnancies (21.6% per ongoing pregnancy). In conclusion, the pregnancy rate per IUI cycle in The Netherlands (9.0%) was comparable with that reported in the international literature (8.7%). The contribution made by IUI to the number of multiple pregnancies in The Netherlands was much smaller than the contribution made by IVF.

Abstract
BACKGROUND The usefulness of GnRH antagonists in mild controlled ovarian hyperstimulation (COH) and intrauterine insemination (IUI) cycles is debated. METHODS Two-hundred and ninety-nine couples with unexplained or mild male factor infertility were enrolled in this international multicentre randomized controlled trial. Women allocated to the GnRH antagonist group (n=148) received 50 IU recombinant FSH starting on day 3 of the menstrual cycle and Ganirelix 0.25 mg daily starting from the day in which a follicle with a mean diameter of 13-14 mm was visualized at ultrasound. Women allocated to the control group (n=151) were administered only 50 IU recombinant FSH starting on day 3 of the menstrual cycle. Couples were recruited only for their first treatment cycle. The primary outcome was the clinical pregnancy rate per initiated cycle. RESULTS Baseline characteristics of the two treatment groups were similar. Clinical pregnancy rates per initiated cycle in women who did and did not receive GnRH antagonists were 12.2 and 12.6%, respectively (P=1.00). The relative risk of conception (95% confidence interval) for the use of GnRH antagonists was 1.0 (0.5-1.9). CONCLUSIONS In mild COH and IUI cycles, any benefit of the use of GnRH antagonists in improving pregnancy rates is <2-fold increase.

Abstract
The study evaluated the impact of elevated oestradiol concentrations on pregnancy loss during the first trimester in singleton gestations conceived via ovarian stimulation and intracytoplasmic sperm injection (ICSI). Following determination of oestradiol concentrations during 6478 ICSI cycles, patients were assorted by oestradiol percentile. Hyper-responders were defined as patients having peak oestradiol concentrations over the 90th percentile (>4200 pg/ml, 685 cycles), moderate responders were defined as patients having peak oestradiol concentrations between the 75th and 90th percentiles (3250-4200 pg/ml, 958 cycles) and normal responders were defined as patients having peak oestradiol concentrations between the 25th and 75th percentiles (1350-3250 pg/ml, 3325 cycles). The relationship between first trimester miscarriage rates and oestradiol percentiles was analysed in 1184 singleton gestations. Pregnancy rate was significantly lower in normal responders (54.4%) than in moderate (58.8%, P = 0.02) and hyper-responders (60.9%, P = 0.003), but there were no intergroup differences in miscarriage rate (19.6%, 17.1%, and 16.8%, respectively). Although women with severe ovarian hyperstimulation syndrome had a miscarriage rate of 40%, this rate did not differ significantly from the miscarriage rates of the other groups. The findings suggest that high oestradiol concentrations during ovarian stimulation do not expose singleton pregnancies to an increased risk of miscarriage during the first trimester.

Abstract
Multiple pregnancies following assisted reproductive techniques (ART) became an epidemic in the early nineties. Since then, most European countries have tried to apply restrictive policies to avoid multiples and high order multiples as far as possible. Those pregnancies may cause severe consequences to both the fetuses and mother. Economic, social and ethical dilemmas are also avoidable if caution is exercised when using ART to achieve those pregnancies. When restrictive policies are used in ovulation induction and in vitro fertilization, the results show a clear reduction in the number of MP maintaining satisfactory rates.

Fertil Steril 2006; 85:619-24. [PMID: 16500328 DOI: 10.1016/j.fertnstert.2005.09.021] [Citation(s) in RCA: 42] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2005] [Revised: 09/06/2005] [Accepted: 09/06/2005] [Indexed: 11/23/2022]
Abstract
OBJECTIVE To employ protocols of mild ovarian stimulation to prevent an excessively elevated rate of high-order multiple pregnancies. DESIGN Case series. SETTING University hospital. PATIENT(S) Six hundred and twenty one consecutive patients undergoing 1,259 controlled ovarian hyperstimulation and intrauterine insemination cycles. INTERVENTION(S) Patients received 50 IU per day of recombinant follicle-stimulating hormone (FSH) starting the third day of the cycle, then a gonadotropin-releasing hormone (GnRH) antagonist on the day in which a follicle > or =13 mm was visualized. Cycles were canceled if three or more follicles > or =16 mm and/or five or more follicles > or =11 mm were detected. MAIN OUTCOME MEASURE(S) Rate of high-order multiple pregnancies. RESULT(S) The clinical pregnancy rate per initiated cycle was 9.2% (95% confidence interval, 7.5-11.1%). The incidence of twins and high-order multiple pregnancies was 9.5% (95% CI, 5.3-16.2%) and 0 (0.0-3.2%), respectively. CONCLUSION(S) In controlled ovarian hyperstimulation and intrauterine insemination cycles, a protocol of 50 IU of recombinant FSH daily combined with the use of GnRH antagonists and a policy of strict cancellation based on echographic criteria are associated with a satisfactory pregnancy rate per initiated cycle and a low risk of high-order multiple pregnancies.

Abstract
OBJECTIVE To evaluate the results of two different methods of insemination: fallopian tube sperm perfusion (FSP) with 4 mL of inseminate and intrauterine tuboperitoneal insemination (IUTPI) with 10 mL of inseminate. DESIGN Prospective randomized clinical study. SETTING Private infertility center. PATIENT(S) Two hundred seventy-six couples, undergoing 403 cycles, with unexplained infertility, mild or moderate male infertility, or mild or moderate endometriosis. INTERVENTION(S) Patients were assigned randomly to either FSP (group A, n = 138) or IUTPI (group B, n = 138) treatment. Both groups followed the same mild ovarian stimulation protocol. MAIN OUTCOME MEASURE(S) Ninety-five overall pregnancies: 35 in group A (FSP) and 60 in group B (IUTPI). RESULT(S) The pregnancy rate per cycle (presence of gestational sac with heart beats) was 17.6% in group A (n = 199) and 29.4% in group B (n = 204). These differences were statistically significant (P < .007). The odds ratio of getting pregnant, per patient, in group B was 2.26 (95% confidence interval 1.36-3.77) compared with group A. CONCLUSION(S) The results of this study indicate that IUTPI may prove to be a useful technique in the treatment of unexplained infertility, mild or moderate male infertility, and mild or moderate endometriosis. Three attempts of IUTPI may be beneficial before moving on to more invasive and expensive methods of assisted reproduction techniques.

Abstract
In their quest for a child, infertile couples embark on a journey that is full of expectations and hopes. Over recent years, treatment procedures for assisted conception have become safer and more efficient. However, couples undergoing treatment can still experience some degree of emotional stress due to disappointment if pregnancy is not achieved, or if treatment cycles may have to be cancelled due to a low- or hyper-response. Strategies aimed at minimizing the variability of ovarian response or overall treatment outcome can be expected to significantly reduce this emotional stress. New developments have led to the production of follitropin alfa filled by mass. This is a highly consistent FSH preparation improving the consistency of ovarian response and reducing the risk of cycle cancellation. The impact of this new FSH preparation for assisted reproduction treatments is discussed in this review.
