Relationship between semen regurgitation and pregnancy rates with intrauterine insemination

OBJECTIVE

To evaluate the relationship between semen regurgitation and intrauterine insemination (IUI) outcomes. We hypothesized that clinical pregnancy rates and live birth rates would be reduced when regurgitation occurred.

DESIGN

Retrospective cohort study.

SETTING

A university-based reproductive endocrinology and infertility clinic.

PATIENT(S)

Retrospective review of 1,957 IUI cycles performed on 660 patients between July 2007 and May 2012.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

The primary outcome was live birth. Secondary outcomes were positive serum pregnancy result and clinical pregnancy. Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated using a cluster-weighted generalized estimating equations method to estimate modified Poisson regression models with robust standard errors to account for multiple IUI cycles in the same patient.

RESULT(S)

Live birth rates were similar in IUI cycles with and without regurgitation (6.3% vs. 6.8%, respectively, RR = 0.82, 95% CI [0.53-1.26]). Clinical pregnancy rates in the presence or absence of regurgitation were 10.5% vs. 10.0% (RR = 0.99, 95% CI [0.73-1.35]). Positive serum pregnancy tests after IUI did not differ by regurgitation status (15.0% vs. 15.4%, RR = 0.97, 95% CI [0.75-1.24]). Results were unchanged when adjusted for covariates (age, race and ethnicity, body mass index, duration of infertility, medication, infertility diagnosis, total motile count, and method of sperm preparation).

CONCLUSION(S)

The presence of regurgitation during the IUI procedure is not related to pregnancy outcome.

Effect of an Active vs Expectant Management Strategy on Successful Resolution of Pregnancy Among Patients With a Persisting Pregnancy of Unknown Location: The ACT or NOT Randomized Clinical Trial

IMPORTANCE

Women with an early nonviable pregnancy of unknown location are at high risk of ectopic pregnancy and its inherent morbidity and mortality. Successful and timely resolution of the gestation, while minimizing unscheduled interventions, are important priorities.

OBJECTIVE

To determine if active management is more effective in achieving pregnancy resolution than expectant management and whether the use of empirical methotrexate is noninferior to uterine evacuation followed by methotrexate if needed.

DESIGN, SETTING, AND PARTICIPANTS

This multicenter randomized clinical trial recruited 255 hemodynamically stable women with a diagnosed persisting pregnancy of unknown location between July 25, 2014, and June 4, 2019, in 12 medical centers in the United States (final follow up, August 19, 2019).

INTERVENTIONS

Eligible patients were randomized in a 1:1:1 ratio to expectant management (n = 86), active management with uterine evacuation followed by methotrexate if needed (n = 87), or active management with empirical methotrexate using a 2-dose protocol (n = 82).

MAIN OUTCOMES AND MEASURES

The primary outcome was successful resolution of the pregnancy without change from initial strategy. The primary hypothesis tested for superiority of the active groups combined vs expectant management, and a secondary hypothesis tested for noninferiority of empirical methotrexate compared with uterine evacuation with methotrexate as needed using a noninferiority margin of -12%.

RESULTS

Among 255 patients who were randomized (median age, 31 years; interquartile range, 27-36 years), 253 (99.2%) completed the trial. Ninety-nine patients (39%) declined their randomized allocation (26.7% declined expectant management, 48.3% declined uterine evacuation, and 41.5% declined empirical methotrexate) and crossed over to a different group. Compared with patients randomized to receive expectant management (n = 86), women randomized to receive active management (n = 169) were significantly more likely to experience successful pregnancy resolution without change in their initial management strategy (51.5% vs 36.0%; difference, 15.4% [95% CI, 2.8% to 28.1%]; rate ratio, 1.43 [95% CI, 1.04 to 1.96]). Among active management strategies, empirical methotrexate was noninferior to uterine evacuation followed by methotrexate if needed with regard to successful pregnancy resolution without change in management strategy (54.9% vs 48.3%; difference, 6.6% [1-sided 97.5% CI, -8.4% to ∞]). The most common adverse event was vaginal bleeding for all of the 3 management groups (44.2%-52.9%).

CONCLUSIONS AND RELEVANCE

Among patients with a persisting pregnancy of unknown location, patients randomized to receive active management, compared with those randomized to receive expectant management, more frequently achieved successful pregnancy resolution without change from the initial management strategy. The substantial crossover between groups should be considered when interpreting the results.

Intrauterine insemination performance characteristics and post-processing total motile sperm count in relation to live birth for couples with unexplained infertility in a randomised, multicentre clinical trial

STUDY QUESTION

Are intrauterine insemination (IUI) performance characteristics and post-processing total motile sperm count (TMC) related to live birth rate in couples with unexplained infertility?

SUMMARY ANSWER

Patient discomfort with IUI and lower inseminate TMC were associated with a reduced live birth rate, while time from hCG injection to IUI, sperm preparation method and ultrasound guidance for IUI were not associated with live birth success.

WHAT IS ALREADY KNOWN

We previously determined that some baseline characteristics of couples with unexplained infertility, including female age, duration of infertility, history of prior loss and income, were related to live birth rate across a course of ovarian stimulation and IUI treatment. However, the relationship between treatment outcomes and per-cycle characteristics, including ultrasound guidance for IUI, timing of IUI relative to hCG injection, difficult or painful IUI and inseminate TMC, are controversial, and most prior investigations have not evaluated live birth outcome.

STUDY DESIGN, SIZE, DURATION

This was a secondary analyses of 2462 cycles from the Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation (AMIGOS) clinical trial. This prospective, randomised, multicentre clinical trial determined live birth rates following IUI after ovarian stimulation with clomiphene citrate, letrozole or gonadotropins in 854 couples with unexplained infertility. It was conducted between 2011 and 2014, and couples could undergo up to four consecutive treatment cycles.

PARTICIPANTS/MATERIALS, SETTING, METHODS

AMIGOS was an NIH-sponsored Reproductive Medicine Network trial conducted at 12 clinical sites. Participants were women with unexplained infertility who were between 18 and 40 years of age. Cluster-weighted generalised estimating equations (GEE), which account for informative clustering of multiple IUI treatment cycles within the same patient, were used to determine associations between IUI performance characteristics, including inseminate TMC, and live birth rate. Efficiency curves were also generated to examine the relationship between inseminate TMC and live birth rate.

MAIN RESULTS AND THE ROLE OF CHANCE

After adjustment for treatment group and baseline factors previously associated with live birth across a course of OS-IUI treatment, patient discomfort during the IUI procedure was associated with a reduction in live birth rate (aRR 0.40 (0.16-0.96)). Time from hCG trigger injection to IUI was not significantly associated with outcome. Higher TMC was associated with greater live birth rate (TMC 15.1-20.0 million (14.8%) compared to ≤5 million (5.5%)) (aRR 2.09 (1.31-3.33)). However, live births did occur with TMC ≤ 1 million (5.1%).

LIMITATIONS, REASONS FOR CAUTION

This investigation is a secondary analysis, and AMIGOS was not designed to address the present question. Since timed intercourse was allowed as part of the AMIGOS trial, we cannot rule out the possibility that any given pregnancy resulted from intercourse rather than IUI.

WIDER IMPLICATIONS OF THE FINDINGS

Most factors associated with the performance of IUI were not significantly related to obtaining live birth. Our findings suggest that higher TMC inseminated leads to an increase in live birth rate up to TMC ~20 million. However, there may be no reasonable threshold below which live birth is not possible with IUI.

TRIAL REGISTRATION NUMBER

n/a.

Pregnancy registry: three-year follow-up of children conceived from letrozole, clomiphene, or gonadotropins

OBJECTIVE

To study the development of children conceived from non-IVF infertility treatments consisting of gonadotropins, clomiphene, or letrozole.

DESIGN

Prospective cohort study.

SETTING

U.S. academic health centers.

PATIENT(S)

Children of women with polycystic ovary syndrome who conceived with letrozole (LTZ) or clomiphene (CC) in the PPCOS II study or women with unexplained infertility (AMIGOS study) who conceived with LTZ, CC, or gonadotropin (GN).

INTERVENTION(S)

Longitudinal annual follow-up from birth to age 3.

MAIN OUTCOME MEASURE(S)

Scores from Ages and Stages Developmental Questionnaire (ASQ), MacArthur-Bates Communicative Development Inventory (MCDI), and annual growth.

RESULT(S)

One hundred eighty-five children from 160 families participated in at least one follow-up evaluation from the two infertility trials. Most multiple gestations in the follow-up study resulted from GN treatment (n = 14) followed by CC (n = 6) and LTZ (n = 3). There were no significant differences among the three groups at any time point with respect to abnormal scores on the ASQ. On the MCDI Words and Gestures, the LTZ group scored significantly higher than the GN group for most items (phrases, early gestures, later gestures, and total gestures). Children in the CC group scored significantly higher than the GN group for the later gestures and total gestures items.

CONCLUSION(S)

Differences in growth and cognitive developmental rates among children conceived with first-line infertility therapies, including LTZ, are relatively minor and likely due to differences in multiple pregnancy rates.

OR11-04 Effect of Preconception Intensive vs. Standard Lifestyle Intervention on Birth Outcomes in Obese Women With Unexplained Infertility: A Multicenter Randomized Trial

We hypothesized that weight loss with an intensive preconception lifestyle (IL) intervention of caloric restriction with meal replacements, daily orlistat and increased physical activity in women with obesity and unexplained infertility (UI) was more likely to result in Good Birth Outcome than a standard lifestyle modification (SL) with increased physical activity alone. The 16 week period of lifestyle modification was followed by an open label empiric infertility treatment regimen of 3 cycles of ovarian stimulation with clomiphene, ovulation triggering with hCG and intrauterine insemination. We randomized 379 obese women 18-40y with UI (regular menses, normal ovarian reserve, patent reproductive tract and normal male factor). A Good Birth Outcome (GBO) was the primary outcome, defined as a live birth of an infant born at ≥37wks with a birthweight between 2500-4000g and no major congenital anomaly. Key secondary outcomes were live birth, pregnancy loss and pregnancy complication rates. The study had 80% power and an alpha of 0.05 to detect an absolute 15% difference in GBO. An Intention-to-Treat analysis was used. Both groups (SL N=191, IL N =188) were well matched at baseline(e.g. weight (kg), mean ± SD, SL:107±21, IL: 108 ±23). Women in the IL arm lost significantly more weight preconception than SL (SL -0.3±3.4 vs IL -7.3±6.6 kg, P<.001) with similar decreases in associated biometric and biochemical parameters. Overall 59.4% of the IL group lost >5% weight vs 6.5% in SL group(P<.001). Despite achieving the targeted weight loss, GBO rate between groups was not significantly different (IL12.2% vs SL 15.2%, IL Rate Ratio, 95% CI: 0.8, 0.5-1.3) or in live birth (IL 20.2% vs SL 22.0%, IL RR: 0.9, 0.6-1.4). Pregnancy loss among women who conceived trended higher in the IL group (IL 38.1% vs SL 23.7%, IL RR:1.6, 0.9-2.8) but miscarriage rates (loss after visualized intrauterine pregnancy), were significantly higher in IL (IL 20.6% vs SL 3.4%, IL RR: 6.1, 1.4-25.8, P=0.005). Birthweights were similar in both groups (IL: 3199±712 vs SL: 3106±794g). Major pregnancy complications trended lower in IL: Preterm Labor (IL 3.2% vs SL 10.2%), Pre-eclampsia (IL 6.3% vs SL 11.9%), Gestational DM (IL 9.5% vs SL 16.9%). Adverse events were more common in the IL group, i.e. increased GI side effects of bloating, flatulence, diarrhea and steatorrhea, likely related to use of orlistat. Moderate weight loss prior to conception does not improve live birth or GBO rates compared to exercise alone in obese women. Of concern, early pregnancy loss is more common when conception occurs after IL intervention. However a benefit to IL modification preconception may be lower perinatal morbidity, although further larger studies are necessary to confirm this potential benefit.

Families with children resulting from ART: psychosocial and financial implications

STUDY QUESTION

What are the psychosocial and financial issues experienced among families with children 2-12 years of age conceived by ART?

SUMMARY ANSWER

Our results suggest that families with children, 2-12 years of age, conceived via ART are doing well, although impacts were identified on parents of twins and higher-order multiples.

WHAT IS KNOWN ALREADY

Multiple births have been associated with higher morbidity and mortality of children, as well as financial costs to families and society.

STUDY DESIGN SIZE DURATION

This study was an assessment of familial response to birth of singletons, twins and higher order multiples at child's ages of 2-12.

PARTICIPANTS/MATERIALS SETTING METHODS

Semi-structured interviews and surveys were conducted with mothers (n = 348) and fathers (n = 338) of singletons, twins and higher-order multiple gestations who received fertility services.

MAIN RESULTS AND THE ROLE OF CHANCE

No significant differences were observed between the groups in domains of primary caregiving or parental separation/divorce. Impacts were identified on parent's ability to maintain employment. The revised 15-item scores of the Impact on Family Scale were significantly lower, reflecting more negative impacts, among families with twins (beta = -2.6, 95% confidence interval (CI), -4.7, -0.5, P = 0.014) and multiples (beta = -7.4, 95% CI, -10.4, -4.5, P < 0.001) than among families with singletons. Similarly, the Parenting Stress Index total scores were significantly lower among families with twins and multiples, indicating greater levels of stress, when compared to those with singletons. In addition, the Beck Depression Inventory total score were significantly higher for twins and multiples, and the Child Behaviour Checklist for ages 1.5-5 total problem score was significantly higher for twins when compared to singletons.

LIMITATIONS REASONS FOR CAUTION

The study was limited to families who received fertility treatment and constitutes a population that was well educated and had higher incomes. Additionally, interview data was self-reported.

The effect of antioxidants on male factor infertility: the Males, Antioxidants, and Infertility (MOXI) randomized clinical trial

OBJECTIVE

To determine whether antioxidants improve male fertility, as measured by semen parameters and DNA fragmentation at 3 months and pregnancy resulting in live birth after up to 6 months of treatment, among couples with male factor infertility.

DESIGN

Multicenter, double-blind, randomized, placebo-controlled trial with an internal pilot study.

SETTING

Nine fertility centers in the United States from December 2015 to December 2018.

PATIENT(S)

Men (N = 174) with sperm concentration ≤15 million/mL, motility ≤40%, normal morphology ≤4%, or DNA fragmentation >25%, and female partners who were ovulatory, ≤40 years old, and had documented tubal patency.

INTERVENTION(S)

Males randomly assigned to receive an antioxidant formulation (n = 85) containing 500 mg of vitamin C, 400 mg of vitamin E, 0.20 mg of selenium, 1,000 mg of l-carnitine, 20 mg of zinc, 1,000 μg of folic acid, 10 mg of lycopene daily, or placebo (n = 86). Treatment lasted for a minimum of 3 months and maximum of 6 months, and couples attempted to conceive naturally during the first 3 months and with clomiphene citrate with intrauterine insemination of the female partner in months 4 through 6.

MAIN OUTCOME MEASURE(S)

Primary outcome was live birth; secondary outcomes included pregnancy within 6 months of treatment. For the internal pilot, the primary outcomes were semen parameters and sperm DNA fragmentation index after 3 months of treatment.

RESULT(S)

In the Males, Antioxidants, and Infertility (MOXI) study, after 3 months of treatment, the change in sperm concentration differed between the antioxidant group (median -4.0 [interquartile range-12.0, 5.7] million/mL) and placebo group (+2.4 [-9.0, 15.5] million/mL). However, there were no statistically significant differences between the two groups for changes in sperm morphology, motility, or DNA fragmentation. Among the 66 oligospermic men at randomization, sperm concentration did not differ at 3 months between the antioxidant and control groups: 8.5 (4.8, 15.0) million/mL versus 15.0 (6.0, 24.0) million/mL. Of the 75 asthenospermic men, motility did not differ at 3 months: 34% ± 16.3% versus 36.4% ± 15.8%. Among the 44 men with high DNA fragmentation, DNA fragmentation did not differ at 3 months: 29.5% (21.6%, 36.5%) versus 28.0% (20.6%, 36.4%). In the entire cohort, cumulative live birth did not differ at 6 months between the antioxidant and placebo groups: 15% versus 24%.

CONCLUSION(S)

Antioxidants do not improve semen parameters or DNA integrity among men with male factor infertility. Although limited by sample size, this study suggests that antioxidant treatment of the male partner does not improve in vivo pregnancy or live-birth rates.

Androgenicity and fertility treatment in women with unexplained infertility

OBJECTIVE

To determine whether biochemical or clinical markers of androgenic activity predict live birth rate with ovarian stimulation in the unexplained infertility population.

DESIGN

Secondary analysis of the Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation (AMIGOS) clinical trial.

SETTING

Multicenter university-based clinical practices.

PATIENT(S)

Nine hundred couples with unexplained infertility were included. Women were 18-40 years old with regular menses, a normal uterine cavity, at least one patent fallopian tube, and a male partner with ≥5 million motile sperm. Women were randomized to receive gonadotropin, clomiphene, or letrozole with IUI for four or fewer four treatment cycles. Women were evaluated for biochemical (total testosterone, DHEAS, and free androgen index) and clinical markers of androgenic activity (sebum, acne, and hirsutism). Multivariable logistic regression models adjusting for treatment group, maternal age, and body mass index were performed.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

The primary outcome was live birth. Secondary outcomes included conception, clinical pregnancy, and pregnancy loss.

RESULT(S)

When comparing 900 women in the AMIGOS trial based on quartiles of serum TT, women were of younger age, higher body mass index, and higher waist circumference with increasing TT. Increasing quartiles of TT also showed increasing DHEAS and free androgen index values. Serum androgens were not associated with outcomes of live birth, conception, clinical pregnancy, or pregnancy loss. Clinical androgen markers were not associated with pregnancy outcomes.

CONCLUSION(S)

In a randomized cohort of women with unexplained infertility, biochemical and clinical measures of androgens did not predict live birth rate after ovarian stimulation treatment.

Human chromatin remodeler cofactor, RNA interactor, eraser and writer sperm RNAs responding to obesity

In the United States almost 33% of adults are considered obese (BMI > 30 kg/m2). Both animal models and to a lesser extent human studies, have associated BMI, a measure of obesity, with alterations in sperm DNA methylation and RNAs. Sperm RNAs from the Assessment of Multiple Gestations from Ovarian Stimulation trial, were isolated and sequenced. A Generalized Linear Model identified 487 BMI associated human sperm RNA elements (short exon-sized sequences). They partitioned into four patterns; a continual increase with BMI, increase once obese (BMI>30 kg/m2); a steady decrease with BMI; and decrease once overweight (BMI 25 - 30 kg/m2). Gene Ontology revealed a unique relationship between BMI and transcripts associated with chromosome organization, adipogenesis, cellular stress and obesity-related inflammation. Coregulatory networks linked by Chromatin remodeler cofactors, RNA interactors, Erasers and Writers (CREWs) were uncovered to reveal a hierarchical epigenetic response pathway.

Do BRCA1 and BRCA2 gene mutation carriers have a reduced ovarian reserve? Protocol for a prospective observational study

INTRODUCTION

BRCA1/2 gene mutations increase risk of breast and/or ovarian cancer and may have implications for reproductive health. Indirect biomarkers of the ovarian primordial follicle pool (anti-Müllerian hormone (AMH)) and one small study in female cadavers suggest that ovarian reserve may be reduced in BRCA mutation carriers, but findings are conflicting and association between circulating AMH and primordial follicle number is not established. The aim of this study is to measure primordial follicle density in premenopausal ovarian tissue samples from women with BRCA1/2 gene mutations versus age-matched comparison group.

METHODS AND ANALYSIS

Prospective observational study measuring associations between BRCA gene mutation status, premenopausal ovarian primordial follicle density and serum AMH concentrations versus age-matched premenopausal women from the general population. Primordial follicle density will be measured in cortical sections from ovarian tissue collected at the time of risk-reducing bilateral salpingo-oophorectomy (RRBSO) in 88 BRCA1 gene mutation carriers, 65 BRCA2 gene mutation carriers and 157 non-mutation carriers. Primordial follicle density will be determined by counting follicles in a known volume of ovarian cortical tissue using light microscopy. Follicles will be identified by immunohistochemical staining for oocyte marker mouse vasa homologue. To inform the mechanisms underlying reduced ovarian reserve, the proportion of follicles containing oocytes with DNA damage will be determined by immunohistochemical staining for phosphorylated histone H2AX and terminal deoxynucleotidyl transferase dUTP nick end labelling assay to identify apoptotic cells. Follicle density will be correlated with circulating AMH concentrations quantified in the same cohort, using an electrochemiluminescence immunoassay on an automated platform.

Fertility Related Quality of Life, Gonadal Function and Erectile Dysfunction in Male Partners of Couples with Unexplained Infertility

PURPOSE

We sought to determine whether lower fertility related quality of life or depression in men of couples with unexplained infertility is associated with low total testosterone levels, abnormal semen quality or erectile dysfunction.

MATERIALS AND METHODS

This study is a secondary analysis of a large, multicenter, randomized controlled trial in couples with unexplained infertility. Male partners underwent baseline semen analysis with measurement of fasting total testosterone and gonadotropin. They also completed surveys, including the FertiQOL (Fertility Quality of Life), the PHQ-9 (Patient Health Questionnaire-9) and the IIEF (International Index of Erectile Function). The primary study outcomes were total testosterone with low total testosterone defined as less than 264 ng/dl, semen parameters and the IIEF score. We performed multivariable logistic regression analyses adjusted for patient age, race, body mass index, education, smoking, alcohol use, infertility duration and comorbidity.

RESULTS

A total of 708 men with a mean ± SD age of 34.2 ± 5.6 were included in study. Of the men 59 (8.3%) had a PHQ-9 score of 5 or greater, which was consistent with depression, 99 (14.0%) had low total testosterone and 63 (9.0%) had mild or worse erectile dysfunction. Neither the FertiQOL score nor depression was associated with total testosterone or any semen parameter. The FertiQOL score was inversely associated with erectile dysfunction (for every 5-point score decline AOR 1.30, 95% CI 1.16-1.46). Depressed men were significantly more likely to have erectile dysfunction than nondepressed men (AOR 6.31, 95% CI 3.12-12.77).

CONCLUSIONS

In men in couples with unexplained infertility lower fertility related quality of life and depression are strongly associated with erectile dysfunction. However, neither is associated with spermatogenesis or testosterone levels. Erectile dysfunction in infertile men merits longitudinal investigation in future studies.

Association between testosterone, semen parameters, and live birth in men with unexplained infertility in an intrauterine insemination population

OBJECTIVE

To determine whether men with unexplained infertility and low total T (TT) have abnormal spermatogenesis and lower fecundity.

DESIGN

Secondary analysis of the prospective, randomized, multicenter clinical trial, Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation (AMIGOS).

SETTING

Infertility clinics.

PATIENT(S)

Nine hundred couples with unexplained infertility enrolled in AMIGOS. Semen analysis with an ejaculate of at least 5 million total motile sperm was required for enrollment. For inclusion in this secondary analysis, a fasting TT was required.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

Logistic regression, adjusted for age and body mass index, assessed the association between low TT (defined as <264 ng/dL), semen parameters, and pregnancy outcome.

RESULT(S)

Seven hundred eighty-one men (mean age, 34.2 ± 5.7 years) with a median (interquartile range) TT of 411 (318-520) ng/dL were included. Men with TT <264 ng/dL were less likely to have normal (≥4% strict Kruger) morphology (unadjusted odds ratio [OR], 0.56; 95% confidence interval [CI], 0.34, 0.92; adjusted OR, 0.59; 95% CI, 0.35, 0.99). There was no association between low TT and semen volume < 1.5 mL, sperm concentration < 15 × 10⁶/mL, or motility < 40%. Among couples whose male partner had low TT, 21 (18.8%) had a live birth, compared with 184 (27.5%) live births in couples with a male partner having TT > 264 ng/dL. The odds of live birth decreased by 40% in couples whose male partner had low TT (unadjusted OR, 0.60; 95% CI, 0.36, 1.00; adjusted OR, 0.65; 95% CI, 0.38, 1.12).

CONCLUSION(S)

In couples with unexplained infertility, low TT in the male partner was associated with abnormal sperm morphology and lower live birth rates.

Lower prevalence of non-cavity-distorting uterine fibroids in patients with polycystic ovary syndrome than in those with unexplained infertility

OBJECTIVE

To study whether there is a difference in the prevalence of non-cavity-distorting uterine fibroids between infertile patients with polycystic ovary syndrome (PCOS) and those with unexplained infertility (UI).

DESIGN

A secondary analysis of data from three randomized clinical trials.

SETTING

Academic health centers.

PATIENT(S)

A total of 2,249 patients with normal uterine cavities.

INTERVENTIONS(S)

None.

MAIN OUTCOME MEASURE(S)

The presence or absence of non-cavity-distorting fibroids.

RESULT(S)

Compared with women with UI, those with PCOS were younger, had a higher body mass index, and were more likely to be Hispanic or African American, with a lower percentage of previous conception and live birth, a higher percentage of current smokers, a lower percentage of current alcohol users, and higher total testosterone, fasting insulin, and homeostasis-model-assessment insulin resistance. The prevalence of women with non-cavity-distorting uterine fibroids was lower in women with PCOS than in those with UI (6.7% vs. 12.4%); this result held after patients were divided into Black and non-Black or into three different body mass index groups. After adjustment for all the other variables in the final model, patients with PCOS had a significantly lower prevalence of fibroids than those with UI (odds ratio 0.54). No differences in the prevalence of non-cavity-distorting fibroids with any dimensions ≥4 cm or the volume of the largest fibroid was found between the two groups.

CONCLUSION(S)

A lower prevalence of non-cavity-distorting uterine fibroids was found in infertile women with PCOS than in those with UI.

Gestational Weight Gain in Women With Polycystic Ovary Syndrome: A Controlled Study

CONTEXT

Women with polycystic ovary syndrome (PCOS) have increased risk for pregnancy complications, possibly related to pre-existing obesity and excessive gestational weight gain (GWG).

OBJECTIVES

To assess the contributions of diagnosis and preconception weight on GWG and perinatal outcomes.

RESEARCH DESIGN AND METHODS

Prospective cohort study of singleton pregnancies in PCOS (n = 164) and ovulatory controls (n = 176) from infertility treatment.

MAIN OUTCOME MEASURES

GWG, birthweight, pregnancy complications.

RESULTS

From preconception baseline, normal-weight women with PCOS gained 2.3 pounds more during the first trimester (95% CI, 0.3 to 4.3; P = 0.02), and by the end of the second trimester, 4.2 pounds more than controls (95% CI, 0.7 to 7.7; P = 0.02). Women who were overweight with PCOS gained significantly more weight than did controls by the end of the second trimester (5.2 pounds; 95% CI, 0.2 to 10.2; P = 0.04), whereas women with obesity and PCOS and control women had similar weight gain throughout pregnancy. Within normal-weight, overweight, and obese groups, prevalence of pre-eclampsia and gestational diabetes did not differ between the PCOS and control groups, nor was there a difference in birthweight. Preconception body mass index (BMI) was significantly associated with GWG; for every 1-kg/m2 increase in preconception BMI, GWG decreased by 0.62 pounds (95% CI, -0.85 to -0.40; P < 0.001).

CONCLUSIONS

Women with PCOS who are of normal weight or are overweight before conception experience more GWG than do ovulatory controls. Within normal-weight, overweight, and obese groups, rates of perinatal complications do not significantly differ between women with PCOS and controls. Preconception BMI is the strongest predictor of GWG.

The efficiency of single institutional review board review in National Institute of Child Health and Human Development Cooperative Reproductive Medicine Network-initiated clinical trials

BACKGROUND/AIMS

Timely review of research protocols by institutional review boards leads to more rapid initiation of clinical trials, which is critical to expeditious translation from bench to bedside. This observational study examined the impact of a single institutional review board on time and efforts required to initiate clinical trials by the National Institute of Child Health and Human Development Cooperative Reproductive Medicine Network.

METHODS

Collection of data from the same six main clinical sites for three current clinical trials and two past clinical trials, including time from institutional review board submission to approval, pages submitted, consent form length, number of required attachments, other regulatory requirements, order of review at central or local sites, and language in documents at individual participating sites. Results from two past clinical trials were also included.

RESULTS

While time required for actual institutional review board submission's review and initial approval was reduced with use of a single institutional review board for multicenter trials (from a mean of 66.7-24.0 days), total time was increased (to a mean of 111.2 or 123.3 days). In addition to single institutional review board approval, all institutions required local approval of some components (commonly consent language and use of local language), which varied considerably. The single institutional review board relied on local institutions for adding or removing personnel, conflict of interest review, and auditing of activities.

CONCLUSION

A single institutional review board reduced time for initial review and approval of protocols and informed consents, although time for the entire process was increased, as individual institutions retained oversight of components of required regulatory review. In order to best achieve the National Institute of Health's goals for improved efficiency in initiation and conduct of multisite clinical research, greater coordination with local institutional review boards is key to streamlining and accelerating initiation of multisite clinical research.

Optimal treatment for women with a persisting pregnancy of unknown location, a randomized controlled trial: The ACT-or-NOT trial

OBJECTIVE

Pregnancy of unknown location (PUL) is not a diagnosis but a transient state used to classify a woman when she has a positive pregnancy test without definitive evidence of an intra-uterine or extra-uterine pregnancy on transvaginal ultrasonography. Management of a persisting PUL varies substantially, including expectant or active management. Active management can include uterine cavity evacuation or systemic administration of methotrexate. To date, no consensus has been reached on whether either management strategy is superior or non-inferior to the other.

DESIGN

Randomized controlled trial.

SETTING

Academic medical centers.

PATIENTS

We plan to randomize 276 persisting PUL-diagnosed women who are 18 years or older from Reproductive Medicine Network clinics and additional interested sites, all patients will be followed for 2 years for fertility and patient satisfaction outcomes.

INTERVENTIONS

Randomization will be 1:1:1 ratio between expectant management, uterine evacuation and empiric use of methotrexate. After randomization to initial management plan, all patients will be followed by their clinicians until resolution of the PUL. The clinician will determine whether there is a change in management, based on clinical symptoms, and/or serial human chorionic gonadotropin (hCG) concentrations and/or additional ultrasonography.

MAIN OUTCOME

The primary outcome measure in each of the 3 treatment arms is the uneventful clinical resolution of a persistent PUL without change from the initial management strategy. Secondary outcome measures include: number of ruptured ectopic pregnancies, number and type of re-interventions (additional methotrexate injections or surgical procedures), treatment complications, adverse events, number of visits, time to resolution, patient satisfaction, and future fertility.

CONCLUSION

This multicenter randomized controlled trial will provide guidance for evidence-based management for women who have persisting pregnancy of unknown location.

Comparison of sonohysterography to hysterosalpingogram for tubal patency assessment in a multicenter fertility treatment trial among women with polycystic ovary syndrome

PURPOSE

To compare saline infusion sonohysterography (SIS) versus hysterosalpingogram (HSG) for confirmation of tubal patency.

METHODS

Secondary analysis of a randomized controlled trial, Pregnancy in Polycystic Ovary Syndrome II (PPCOS II). Seven hundred fifty infertile women (18-40 years old) with polycystic ovary syndrome (PCOS) were randomized to up to 5 cycles of letrozole or clomiphene citrate. Prior to enrollment, tubal patency was determined by HSG, the presence of free fluid in the pelvis on SIS, laparoscopy, or recent intrauterine pregnancy. Logistic regression was conducted in patients who ovulated with clinical pregnancy as the outcome and HSG or SIS as the key independent variable.

RESULTS

Among women who ovulated, 414 (66.9%) had tubal patency confirmed by SIS and 187 (30.2%) had at least one tube patent on HSG. Multivariable analysis indicated that choice of HSG versus SIS did not have a significant relationship on likelihood of clinical pregnancy, after adjustment for treatment arm, BMI, duration of infertility, smoking, and education (OR 1.14, 95% CI 0.77, 1.67, P = 0.52). Ectopic pregnancy occurred more often in women who had tubal patency confirmed by HSG compared to SIS (2.8% versus 0.6%, P = 0.02).

CONCLUSIONS

In this large cohort of women with PCOS, there was no significant difference in clinical pregnancy rate between women who had tubal patency confirmed by HSG versus SIS. SIS is an acceptable imaging modality for assessment of tubal patency in this population.
