Histological ovarian features and hormonal determinations in assigned females at birth transgender individuals according to different testosterone preparations.

Introduction: Distinct androgen formulations have been used as gender-affirming hormone treatment, but little is known about the specific changes that may occur in the ovary depending on the testosterone preparation used. The study aims to evaluate the histological modifications of the ovarian tissue and the hormonal changes after gender-affirming surgery based on the testosterone preparation employed, such as testosterone cypionate or undecanoate.

Design: Unicenter transversal cohort study.

Basal characteristics of patients who responded to Ovarian Fragmentation for Follicular Activation (OFFA) or In Vitro Activation (IVA): a systematic review and meta-analysis.

A systematic review and meta-analysis were performed to identify if there is a subset of patients with POI who are more likely to show follicular growth after ovarian fragmentation for follicular activation (OFFA) or in vitro activation (IVA). Five studies met inclusion criteria for meta-analysis with a total of 164 patients. Forty-three patients showed follicle development (26.

Current status of fertility preservation in a Spanish tertiary public hospital: multidisciplinary approach and experience in over 1500 patients.

Purpose: Currently, 15% of gynaecological and 9% of haematological malignancies are diagnosed before the age of 40. The increased survival rates of cancer patients who are candidates for gonadotoxic treatments, the delay in childbearing to older ages, and the optimization of in vitro fertilisation techniques have all contributed to an increased interest in fertility preservation (FP) treatments. This study reviews the experience of the Fertility Preservation Programme (FPP) of a tertiary public hospital with a multidisciplinary approach.

Antral follicle count measured at down-regulation as predictor of ovarian response and cumulative live birth: single center analysis including 2731 long agonist IVF cycles.

Objective: Evaluate antral follicle count measured after pituitary suppression (AFCaps) with a GnRH agonist as predictor of ovarian response and cumulative live birth (CLB).

Methods: This study is a large cohort analysis of retrospective data between January 2011 and September 2020 in a tertiary-care university hospital. All first initiated IVF/ICSI cycles in women under 43 years of age for whom AFCaps was registered in our database were included.
