ABSTRACT
OBJECTIVE: To determine whether the racial and ethnic distribution of sperm donors contributing to US sperm banks differs from the demographics of the US population and those of US donor sperm recipients undergoing treatment with in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). DESIGN: Cross-sectional study. SETTING: United States donor sperm banks, US Census, and fertility clinics reporting to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System. PATIENTS: Sperm donors from 18 banks, men aged 18-39 years on the basis of the 2021 Census Current Population Survey, and recipients of donor sperm for IVF and ICSI treatments in clinics reporting to the Assisted Reproductive Technology Clinic Outcome Reporting System from January 1, 2018, to December 31, 2020. INTERVENTION: None. MAIN OUTCOME MEASURE: Proportions of sperm donors and donor sperm recipients undergoing IVF and ICSI treatments identifying as each racial and ethnic group. RESULTS: Eighteen donor sperm banks were identified, encompassing 1,503 donors. Of these donors, 60.9% identified as White compared with 55.1% of the US male population and 67.7% of donor sperm recipients. Proportions of donors identifying as Asian or 2 or more races were larger than those of US men and donor sperm recipients (Asian: 18.6% vs. 6.5%, and 18.6% vs. 10.2%; 2 or more races: 11.6% vs. 2.2%, and 11.6% vs. 1.7%). In contrast, Black donors were underrepresented when compared with the US population of men and donor sperm recipients (2.8% vs. 12.9% and 2.8% vs. 13.0%). Hispanic donors were underrepresented when compared with the US population of men (6.0% vs. 22.2%). The percentages of Hispanic sperm donors and donor sperm recipients were similar (6.0% vs. 7.0%). CONCLUSION: The racial and ethnic distribution of sperm donors differs significantly from the demographics of the US male population and donor sperm recipients undergoing IVF and ICSI treatments. These findings suggest a need for targeted recruitment efforts for Black sperm donors.
ABSTRACT
BACKGROUND: To examine the association between maternal education and adverse maternal and neonatal outcomes in women who conceived using medically assisted reproduction, which included fertility medications, intrauterine insemination, or in vitro fertilization. METHODS: We conducted a retrospective cohort study utilizing the US Vital Statistics data set on national birth certificates from 2016 to 2020. Women with live, non-anomalous singletons who conceived using MAR and had education status of the birthing female partner recorded were included. Patients were stratified into two groups: bachelor's degree or higher, or less than a bachelor's degree. The primary outcome was a composite of maternal adverse outcomes: intensive care unit (ICU) admission, uterine rupture, unplanned hysterectomy, or blood transfusion. The secondary outcome was a composite of neonatal adverse outcomes: neonatal ICU admission, ventilator support, or seizure. Multivariable modified Poisson regression models with robust error variance adjusted for maternal age, race, marital status, prenatal care, smoking during pregnancy, neonatal sex, and birth year estimated the relative risk (RR) of outcomes with a 95% confidence interval (CI). RESULTS: 190,444 patients met the inclusion criteria: 142,943 had a bachelor's degree or higher and 47,501 were without a bachelor's degree. Composite maternal adverse outcomes were similar among patients with a bachelor's degree (10.1 per 1,000 live births) and those without a bachelor's degree (9.4 per 1,000 live births); ARR 1.05, 95% CI (0.94-1.17). However, composite adverse neonatal outcomes were significantly lower in women with a bachelor's degree or higher (94.1 per 1,000 live births) compared to women without a bachelor's degree (105.9 per 1,000 live births); ARR 0.91, 95% CI (0.88-0.94). CONCLUSIONS: Our study demonstrated that lower maternal education level was not associated with maternal adverse outcomes in patients who conceived using MAR but was associated with increased rates of neonatal adverse outcomes. As access to infertility care increases, patients who conceive with MAR may be counseled that education level is not associated with maternal morbidity. Further research into the association between maternal education level and neonatal morbidity is indicated.
