Project description:ObjectiveTo identify baseline characteristics of couples that are likely to predict conception, clinical pregnancy, and live birth after up to four cycles of ovarian stimulation with IUI in couples with unexplained infertility.DesignSecondary analyses of data from a prospective, randomized, multicenter clinical trial investigating pregnancy, live birth, and multiple pregnancy rates after ovarian stimulation-IUI with clomiphene citrate, letrozole, or gonadotropins.SettingOutpatient clinical units.Patient(s)Nine-hundred couples with unexplained infertility who participated in the Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation clinical trial.Intervention(s)As part of the clinical trial, treatment was randomized equally to one of three arms and continued for up to four cycles or until pregnancy was achieved.Main outcome measure(s)Conception, clinical pregnancy, and live-birth rates.Result(s)In a multivariable logistic regression analysis, after adjustment for other covariates, age, waist circumference, income level, duration of infertility, and a history of prior pregnancy loss were significantly associated with at least one pregnancy outcome. Other baseline demographic and lifestyle characteristics including smoking, alcohol use, and serum levels of antimüllerian hormone were not significantly associated with pregnancy outcomes.Conclusion(s)While age and duration of infertility were significant predictors of all pregnancy outcomes, many other baseline characteristics were not. The identification of level of income as a significant predictor of outcomes independent of race and education may reflect differences in the underlying etiologies of unexplained infertility or could reveal disparities in access to fertility and/or obstetrical care.Clinical trial registrationNCT01044862.

Project description:ObjectiveTo identify risk factors for pregnancy outcomes in couples treated with intracervical or intrauterine insemination, with or without superovulation for unexplained or male-factor infertility.DesignSecondary analysis of data from a randomized superovulation and intrauterine insemination trial.SettingAcademic medical centers.Intervention(s)Treatment continued for four cycles unless pregnancy was achieved.Patient(s)Out of 932 couples randomized to four treatment groups, 664 couples who had completed the lifestyle questionnaires were assessed for occurrence of pregnancy and live birth.Main outcome measure(s)Pregnancy and live birth.Result(s)The pregnancy and live birth rates were significantly higher in couples in which the female partners reported that they had consumed coffee or tea in the past or drank alcoholic beverages in the past (past users) compared with those who had never consumed coffee, tea, or alcoholic beverages. Past users also had significantly higher pregnancy and live birth rates than those currently consuming coffee or tea or alcoholic beverages. Demographic, occupational exposure, and other lifestyle factors were not significant.Conclusion(s)Couples in which the female partners drank coffee, tea, or alcoholic beverages in the past had higher pregnancy and live birth rates compared with never or current users. When discontinuing these habits, they might have made other lifestyle changes to improve the pregnancy outcome.

Project description:ObjectiveTo determine whether men with unexplained infertility and low total T (TT) have abnormal spermatogenesis and lower fecundity.DesignSecondary analysis of the prospective, randomized, multicenter clinical trial, Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation (AMIGOS).SettingInfertility 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.Clinical trial registration numberNCT01044862.

Project description:PURPOSE:To examine the efficacy of motile sperm organelle morphology examination (MSOME) and intracytoplasmic morphologically-selected sperm injection (IMSI) for unexplained infertility. METHODS:This historical study, included 271 couples with primary, unexplained infertility/male subfertility, treated at an outpatient, IVF clinic, 2015-2018. These couples underwent MSOME after ?3 failed intrauterine insemination (IUI) cycles and ?1 failed IVF-ICSI cycle. They proceeded to intracytoplasmic morphologically-selected sperm injection (IMSI) within 6 months of MSOME. IMSI is conducted on the day of oocyte pick-up with a fresh semen sample. Pregnancy and delivery rates were analyzed. RESULTS:The cohort was divided based on percentage of normal cells at MSOME: Group A included 55 with no normal cells, Group B, 184 with 0.5%? normal cells ?1.5% and Group C, 32 with ?2% normal cells. Normal spermatozoa were found in 49 (89%) of Group A after extensive search. Group A had higher pregnancy rate (62.7%) compared to B (47.2%, P = 0.05) and C (28.1%, P = 0.002). Group B had higher pregnancy rate than C (p = 0.045). Delivery rate was higher in Group A (52.1%) compared to B (34.1%, p = 0.023) and C (21.9%, p = 0.007). Pregnancy and delivery rates were higher in A compared to B+C (p = 0.018, p = 0.01, respectively). CONCLUSIONS:MSOME may be useful for evaluating unexplained infertility. IMSI can be recommended for men with <2% normal spermatozoa at MSOME.

Project description:BACKGROUND/AIMS:A large proportion of men with normal sperm results as analyzed using conventional techniques have fragmented DNA in their spermatozoa. We performed a prospective study to examine the incidence of DNA fragmentation in sperm in cases of couples with previously unexplained infertility and treated with intrauterine insemination. We evaluated whether there was any predictive value of DNA fragmentation for pregnancy outcome in such couples. METHODS:The percentage of DNA fragmentation and all classical variables to evaluate sperm before and after sperm treatment were determined. We studied the probable association between these results and pregnancy outcome in terms of clinical and ongoing pregnancy rate per started first cycle. We also assessed the optimal threshold level to diagnose DNA fragmentation in our center. RESULTS:When using threshold levels of 20, 25, and 30%, the occurrence of DNA fragmentation was 42.9, 33.3, and 28.6%, respectively. Receiver operating characteristic (ROC) analysis of all cases revealed an area under the curve of 80% to predict the clinical pregnancy rate per cycle from testing the sperm motility (a?+?b) before treatment. We failed to generate an ROC curve to estimate pregnancy outcome from the amount of DNA fragmentation before treatment. However, when selecting only those men with a pretreatment DNA fragmentation of at least 20%, the pretreatment result was statistically different between couples who achieved a clinical pregnancy and those who did not. CONCLUSION:DNA fragmentation is often diagnosed in couples with unexplained infertility. Each center should evaluate the type of test it uses to detect DNA fragmentation in sperm and determine its own threshold values.

Project description:ObjectiveTo characterize relationships associated with adverse endometrial development in patients undergoing IUI for unexplained infertility.DesignA retrospective review of 2,929 patients from 2004-2011.SettingLarge metropolitan infertility practice.Patient(s)Patients with unexplained infertility undergoing first IUI cycle at age less than 43 years, with a total motile sperm count ≥ 8 million.Intervention(s)Clomiphene citrate (CC) with FSH stimulation followed by IUI.Main outcome measure(s)Endometrial thickness, serum E2 (in picograms per milliliter) levels on the day of hCG trigger administration, body mass index (BMI) (in kilograms per meter squared), total motile sperm, follicle number, and clinical pregnancy.Result(s)Of the 2,929 patients who met the inclusion criteria, 466 (15.9 %) achieved a clinical pregnancy. Pregnancy rates (PRs) increased significantly with increasing endometrial thickness on the day of hCG administration and with increasing serum E2 level, but were not significantly related to age, BMI, or follicle numbers according to multiple logistic regression modeling. Peak endometrial thickness declined with age and increasing E2 levels. The BMI was associated with thicker endometrium, but it was also associated with lower peak E2 levels.Conclusion(s)The impact of "endometrial factor" infertility may be underappreciated in IUI therapy. Targeted therapies to optimize the endometrium represent an important new area to improve in current fertility success rates.

Project description:ObjectiveTo investigate the association of non-cavity-distorting uterine fibroids and pregnancy outcomes after ovarian stimulation-intrauterine insemination (OS-IUI) in couples with unexplained infertility.DesignSecondary analysis from a prospective, randomized, multicenter clinical trial investigating fertility outcomes after OS-IUI.SettingReproductive Medicine Network clinical sites.Patient(s)Nine hundred couples with unexplained infertility who participated in the Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation (AMIGOS) clinical trial.Intervention(s)Participants were randomized to one of three arms (clomiphene citrate, letrozole, or gonadotropins), and treatment was continued for up to four cycles or until pregnancy was achieved.Main outcomes measure(s)Conception (serum hCG increase), clinical pregnancy (fetal cardiac activity), and live birth rates.Result(s)A total of 102/900 participants (11.3%) had at least one documented fibroid and a normal uterine cavity. Women with fibroids were older, more likely to be African American, had a greater uterine volume, lower serum antimüllerian hormone levels, and fewer antral follicles than women without fibroids. In conception cycles, clinical pregnancy rates were significantly lower in participants with fibroids than in those without uterine fibroids. Pregnancy loss before 12 weeks was more likely in African American women with fibroids compared with non-African American women with fibroids. There was no difference in conception and live birth rates in subjects with and without fibroids.Conclusion(s)No differences were observed in conception and live birth rates in women with non-cavity-distorting fibroids and those without fibroids. These findings provide reassurance that pregnancy success is not impacted in couples with non-cavity-distorting fibroids undergoing OS-IUI for unexplained infertility.Clinical trial registration numberNCT01044862.

Project description:Unexplained infertility affects about one-third of infertile couples and is defined as the failure to identify the cause of infertility despite extensive evaluation of the male and female partners. Therefore, there is a need for a multiparametric approach to study sperm function. Recently, we developed a Fluorescence-Based Ratiometric Analysis of Sperm Centrioles (FRAC) assay to determine sperm centriole quality. Here, we perform a pilot study of sperm from 10 fertile men and 10 men in couples with unexplained infertility, using three centriolar biomarkers measured at three sperm locations from two sperm fractions, representing high and low sperm quality. We found that FRAC can identify men from couples with unexplained infertility as the likely source of infertility. Higher quality fractions from 10 fertile individuals were the reference population. All 180 studied FRAC values in the 10 fertile individuals fell within the reference population range. Eleven of the 180 studied FRAC values in the 10 infertile patients were outliers beyond the 95% confidence intervals (P = 0.0008). Three men with unexplained infertility had outlier FRAC values in their higher quality sperm fraction, while four had outlier FRAC values in their lower quality sperm fraction (3/10 and 4/10, P = 0.060 and P = 0.025, respectively), suggesting that these four individuals are infertile due, in part, to centriolar defects. We propose that a larger scale study should be performed to determine the ability of FRAC to identify male factor infertility and its potential contribution to sperm multiparametric analysis.

Project description:Role of intrauterine insemination (IUI) in infertile couples is evaluated. Patients selected for the study belonged to two categories-Unexplained infertility(34 patients) and Male infertility (30 patients). In all the patients selected for IUI ovarian hyperstimulation was carried out with clomiphene citrate. Two techniques of sperm preparation were used - swim-up technique and mono-percoll gradient separation technique. Pregnancy rates of 15.6% per patient and 7% per cycle respectively were achieved which are comparable with other studies. Mono-percoll sperm separation technique was found more effective in treatment of Male infertility (oligo-asthenospermic semen sample).
