RESUMO
RESEARCH QUESTION: Does the composite morphology score or a particular developmental component (expansion stage, inner cell mass [ICM] or trophectoderm [TE]) of euploid blastocysts undergoing single frozen embryo transfer (FET) impact ongoing pregnancy/live birth (OP/LB) rates? DESIGN: Retrospective cohort study including a total of 2236 embryos from 1629 patients who underwent single euploid FET between 2012 and 2017. RESULTS: Embryos with an ICM grade of A compared with C had a higher OP/LB rate (55.6% versus 32.3%, P < 0.001). Blastocysts with a TE grade of A or B compared with C had a higher likelihood of OP/LB (A versus C: odds ratio [OR] 1.6, 99% confidence interval [CI] 1.1-2.3, B versus C: OR 1.5, 99% CI 1.1-2.1), and blastocysts with a developmental stage of 4 or 5 compared with 6 had higher odds of OP/LB (4 versus 6: OR 1.6, 99% CI 1.2-2.2, 5 versus 6: OR 1.6, 99% CI 1.2-2.3). CONCLUSIONS: Among euploid embryos, ICM morphology is the best predictor of sustained implantation; however, a composite score may provide additional guidance. While there is a known benefit in genomic screening prior to embryo selection, morphology provides individualized, prognostic information about implantation potential.

PURPOSE: The study purpose was to evaluate the reproductive experience, specifically cycle characteristics and treatment outcomes, of lesbian women. In addition, we aimed to determine whether there are differences in pregnancy outcomes when comparing lesbian women undergoing ovulation induction (OI) versus natural cycles with donor intrauterine insemination (IUI), as well as lesbian and heterosexual women undergoing the same assisted reproductive technology treatment. METHODS: This was a retrospective cohort study including women who underwent an IUI with cryopreserved sperm between 2006 and 2018. The primary outcome of interest was clinical pregnancy (CP) rate. RESULTS: A total of 216 lesbian women (451 natural cycles and 441 OI cycles) and 584 heterosexual women (1177 natural cycles and 1238 OI cycles) were included in the study. Thirty percent of lesbian women had a hysterosalpingogram as part of their initial workup. Approximately 40% of lesbian women who underwent OI/IUI had previously undergone at least one natural cycle/IUI. There was no significant difference in CP rate when comparing lesbian women and heterosexual women undergoing natural or OI/IUI, or when comparing lesbian women who underwent natural versus OI/IUI cycles. However, there was a significantly higher multiple gestation rate among lesbian women undergoing OI compared with those undergoing natural cycles (11.8% vs. 0%, p = 0.01). CONCLUSION: This large study showed that while pregnancy outcomes were similar between groups, the multiple gestation rate was higher in lesbian women undergoing OI compared with lesbian women undergoing natural cycles.

CONTEXT: The female athlete triad (the triad) is an interrelationship of menstrual dysfunction, low energy availability (with or without an eating disorder), and decreased bone mineral density; it is relatively common among young women participating in sports. Diagnosis and treatment of this potentially serious condition is complicated and often requires an interdisciplinary team. EVIDENCE ACQUISITION: Articles from 1981 to present found on PubMed were selected for review of major components of the female athlete triad as well as strategies for diagnosis and treatment of the conditions. RESULTS: The main goal in treatment of young female athletes with the triad is a natural return of menses as well as enhancement of bone mineral density. While no specific drug intervention has been shown to consistently improve bone mineral density in this patient population, maximizing energy availability and optimizing vitamin D and calcium intake are recommended. CONCLUSIONS: Treatment requires a multidisciplinary approach involving health care professionals as well as coaches and family members. Prevention of this condition is important to minimize complications of the female athlete triad.
