RESUMO
STUDY QUESTION: How does the number of children in women with primary ovarian insufficiency (POI) compare to the number for control women across their reproductive lifespans? SUMMARY ANSWER: Approximately 14% fewer women with POI will have children, but for those able to have children the median number is 1 less than for age-matched controls. WHAT IS KNOWN ALREADY: Women with POI are often identified when presenting for fertility treatment, but some women with POI already have children and there remains a low chance for pregnancy after the diagnosis. Further, POI is heritable, but it is not known whether relatives of women with POI have a smaller family size than relatives of controls. STUDY DESIGN, SIZE, DURATION: The study was a retrospective case-control study of women with POI diagnosed from 1995 to 2021 (n = 393) and age-matched controls (n = 393). PARTICIPANTS/MATERIALS, SETTING, METHODS: Women with POI were identified using ICD9 and 10 codes in electronic medical records (1995-2021) from two major healthcare systems in Utah and reviewed for accuracy. Cases were linked to genealogy information in the Utah Population Database. All POI cases (n = 393) were required to have genealogy information available for at least three generations of ancestors. Two sets of female controls were identified: one matched for birthplace (Utah or elsewhere) and 5-year birth cohort, and a second also matched for fertility status (children present). The number of children born and maternal age at each birth were ascertained by birth certificates (available from 1915 to 2020) for probands, controls, and their relatives. The Mann-Whitney U test was used for comparisons. A subset analysis was performed on women with POI and controls who delivered at least one child and on women who reached 45 years to capture reproductive lifespan. MAIN RESULTS AND THE ROLE OF CHANCE: Of the 393 women with POI and controls, 211 women with POI (53.7%), and 266 controls (67.7%) had at least one child. There were fewer children born to women with POI versus controls (median (interquartile range) 1 (0-2) versus 2 (0-3); P = 3.33 × 10-6). There were no children born to women with POI and primary amenorrhea or those <25 years old before their diagnosis. When analyzing women with at least one child, women with POI had fewer children compared to controls overall (2 (1-3) versus 2 (2-4); P = 0.017) and when analyzing women who reached 45 years old (2 (1-3) versus 3 (2-4); P = 0.0073). Excluding known donor oocyte pregnancies, 7.1% of women with POI had children born after their diagnosis. There were no differences in the number of children born to relatives of women with POI, including those with familial POI. LIMITATIONS, REASONS FOR CAUTION: The data are limited based on inability to determine whether women were trying for pregnancy throughout their reproductive lifespan or were using contraception. Unassisted births after the diagnosis of POI may be slightly over-estimated based on incomplete data regarding use of donor oocytes. The results may not be generalizable to countries or states with late first births or lower birth rates. WIDER IMPLICATIONS OF THE FINDINGS: Approximately half of women with POI will bear children before diagnosis. Although women with POI had fewer children than age matched controls, the difference in number of children is one child per woman. The data suggest that fertility may not be compromised leading up to the diagnosis of POI for women diagnosed at 25 years or later and with secondary amenorrhea. However, the rate of pregnancy after the diagnosis is low and we confirm a birth rate of <10%. The smaller number of children did not extend to relatives when examined as a group, suggesting that it may be difficult to predict POI based on family history.

Treatment for cancer has the potential to significantly diminish fertility and, further, to negatively impact the obstetrical outcomes of pregnancies that do occur. Cancer survivors have decreased rates of fertility and increased rates of pregnancy complications, such as preterm birth and low birth weight, after exposure to chemotherapy. To date, research on the impact of chemotherapy and radiotherapy on fertility and pregnancy outcomes has focused largely on the gonadotoxic effect of cancer treatments on ovaries, while the uterus and endometrium have not been extensively studied. It is intuitive, however, that decreased fertility and poorer obstetrical outcomes may be substantially mediated through injury to a highly mitotic tissue like the endometrium, which is also central to embryo implantation and utero-placental exchange. Pregnancy complications in cancer survivors might be due to compromised blood supply to the endometrium and myometrium affecting placentation or altered remodeling of the pregnant uterus secondary to radiation fibrosis. Alterations in endometrial receptivity at the molecular level could affect pregnancy implantation and early pregnancy loss, but later complications also can occur. This review focuses on understanding the unintended effects of chemotherapy and radiotherapy on uterine function in female cancer survivors and the impact on pregnancy, and summarizes mechanisms to protect and treat the uterus before and after cancer chemotherapy and radiotherapy.

STUDY QUESTION: What are the pain characteristics among women, with no prior endometriosis diagnosis, undergoing laparoscopy or laparotomy regardless of clinical indication? SUMMARY ANSWER: Women with surgically visualized endometriosis reported the highest chronic/cyclic pain and significantly greater dyspareunia, dysmenorrhea, and dyschezia compared with women with other gynecologic pathology (including uterine fibroids, pelvic adhesions, benign ovarian cysts, neoplasms and congenital Müllerian anomalies) or a normal pelvis. WHAT IS KNOWN ALREADY: Prior research has shown that various treatments for pain associated with endometriosis can be effective, making identification of specific pain characteristics in relation to endometriosis necessary for informing disease diagnosis and management. STUDY DESIGN, SIZE, DURATION: The study population for these analyses includes the ENDO Study (2007-2009) operative cohort: 473 women, ages 18-44 years, who underwent a diagnostic and/or therapeutic laparoscopy or laparotomy at one of 14 surgical centers located in Salt Lake City, UT or San Francisco, CA. Women with a history of surgically confirmed endometriosis were excluded. PARTICIPANTS/MATERIALS, SETTING AND METHODS: Endometriosis was defined as surgically visualized disease; staging was based on revised American Society for Reproductive Medicine (rASRM) criteria. All women completed a computer-assisted personal interview at baseline specifying 17 types of pain (rating severity via 11-point visual analog scale) and identifying any of 35 perineal and 60 full-body front and 60 full-body back sites for which they experienced pain in the last 6 months. MAIN RESULTS AND THE ROLE OF CHANCE: There was a high prevalence (≥30%) of chronic and cyclic pelvic pain reported by the entire study cohort regardless of post-operative diagnosis. However, women with a post-operative endometriosis diagnosis, compared with women diagnosed with other gynecologic disorders or a normal pelvis, reported more cyclic pelvic pain (49.5% versus 31.0% and 33.1%, P < 0.001). Additionally, women with endometriosis compared with women with a normal pelvis experienced more chronic pain (44.2 versus 30.2%, P = 0.04). Deep pain with intercourse, cramping with periods, and pain with bowel elimination were much more likely reported in women with versus without endometriosis (all P < 0.002). A higher percentage of women diagnosed with endometriosis compared with women with a normal pelvis reported vaginal (22.6 versus 10.3%, P < 0.01), right labial (18.4 versus 8.1%, P < 0.05) and left labial pain (15.3 versus 3.7%, P < 0.01) along with pain in the right/left hypogastric and umbilical abdominopelvic regions (P < 0.05 for all). Among women with endometriosis, no clear and consistent patterns emerged regarding pain characteristics and endometriosis staging or anatomic location. LIMITATIONS, REASONS FOR CAUTION: Interpretation of our findings requires caution given that we were limited in our assessment of pain characteristics by endometriosis staging and anatomic location due to the majority of women having minimal (stage I) disease (56%) and lesions in peritoneum-only location (51%). Significance tests for pain topology related to gynecologic pathology were not corrected for multiple comparisons. WIDER IMPLICATIONS OF THE FINDINGS: Results of our research suggest that while women with endometriosis appear to have higher pelvic pain, particularly dyspareunia, dysmenorrhea, dyschezia and pain in the vaginal and abdominopelvic area than women with other gynecologic disorders or a normal pelvis, pelvic pain is commonly reported among women undergoing laparoscopy, even among women with no identified gynecologic pathology. Future research should explore causes of pelvic pain among women who seek out gynecologic care but with no apparent gynecologic pathology. Given our and other's research showing little correlation between pelvic pain and rASRM staging among women with endometriosis, further development and use of a classification system that can better predict outcomes for endometriosis patients with pelvic pain for both surgical and nonsurgical treatment is needed.

Our objective was to evaluate the safety and efficacy of clomiphene citrate (CC) in infertile and hypoandrogenic men through a retrospective study between September 2013 and May 2014. We identified 47 men between 18 and 55 years placed on 50 mg CC every other day. We evaluated the effect of CC on testosterone after 2 weeks, rates of adverse effects and predictors of CC response. Mean baseline testosterone, bioavailable testosterone and estradiol were 246.8 ng dl(-1), 125.5 ng dl(-1) and 20.8 pg dl(-1), respectively. At 2 weeks, mean testosterone, bioavailable testosterone and estradiol increased to 527.6 ng dl(-1), 281.8 ng dl(-1) and 32.0 pg dl(-1) (all P<0.001). Two patients at 2 weeks and one patient at 3 months had a paradoxical decrease in testosterone. Mean total motile count (TMC) and concentration increased from 59.7 million (s.e.m.: 16.5) and 50.7 millions ml(-1) (s.e.m.: 11.1) at baseline to 90.9 million (s.e.m.: 25.9) and 72.5 millions ml(-1) (s.e.m.: 17.5), respectively, at 3 months, although this was nonsignificant (P=0.09, 0.09). No patient on CC experienced a paradoxical decrease in TMC or sperm concentration. On age-adjusted regression analysis, age, BMI, longitudinal testis axis, baseline follicle-stimulating hormone, LH and estradiol did not correlate with improvement in bioavailable testosterone at 2 weeks. CC improves testosterone and may improve semen parameters, although a small percentage of men may not demonstrate improvement in testosterone.
