Abstract

Fertility-preservation counseling in the transgender patient population is recommended by multiple organizations, including the American Society for Reproductive Medicine, the World Professional Association for Transgender Health, and the Endocrine Society. The optimal time to pursue fertility preservation has not been established, and data on potential effects of testosterone therapy on future reproductive potential are limited. This Current Commentary seeks to elucidate the most appropriate time to perform oocyte cryopreservation in relation to time on and off testosterone therapy, age of the individual, and emotional effect of treatment. Although there have been multiple studies that have demonstrated successful oocyte cryopreservation regardless of testosterone exposure, the data on live-birth rates after oocyte cryopreservation are limited. Moreover, the process of oocyte cryopreservation may have a significant negative emotional effect on the transgender male given the feminizing effects of gonadotropin stimulation, as well as the invasiveness of pelvic ultrasonograms and the oocyte-retrieval procedure. With our review, we demonstrate that a comprehensive, individualized approach to fertility-preservation counseling and timing to pursue treatment are essential. Postponing fertility-preservation procedures until patients have reached early adulthood might be considered to avoid the potential effect on mental health, without compromising outcomes.

Abstract

Randomized trials of assisted reproductive technology (ART) have been designed for outcomes of clinical pregnancy or live birth and have not been powered for obstetric outcomes such as preeclampsia, critical for maternal and fetal health. ART increasingly involves frozen embryo transfer (FET). Although there are advantages of FET, multiple studies have shown that risk of preeclampsia is increased with FET compared with fresh embryo transfer, and the reason for this difference is not clear. NatPro will compare the proportion of preeclampsia between two commonly used protocols for FET,modified natural and programmed cycle.In this two-arm, parallel-group, multi-center randomized trial, NatPro will randomize 788 women to either modified natural or programmed FET and follow them for up to three FET cycles. Primary outcome will be the proportion of preeclampsia in women with a viable pregnancy assigned to a modified natural cycle FET (corpus luteum present) protocol compared to the proportion of preeclampsia in pregnant women assigned to a programmed FET (corpus luteum absent) protocol. Secondary outcomes will compare the proportion of live births and the proportion of preeclampsia with severe features between the protocols.This study has a potential significant impact on millions of women who pursue ART to build their families. NatPro is designed to provide clinically relevant guidance to inform patients and clinicians regarding maternal risk with programmed and modified natural cycle FET protocols. This study will also provide accurate point estimates regarding the likelihood of live birth with programmed and modified natural cycle FET.ClinicalTrials.gov NCT04551807 .
