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.

Reversible effects of the SARS-CoV-2 on semen parameters.

Despite that the SARS-CoV-2 pandemic has been controlled, it has affected a large proportion of the population, raising some concerns about potential sequelae in men at reproductive age. To contribute to the clarification of this issue, we performed a retrospective study comparing semen parameters values before and after confirmed SARS-CoV-2 infection in a large cohort of infertile men, compared to a control group that did not undergo SARS-CoV-2 infection. Wilcoxon test on paired samples and general linear regression model showed that SARS-CoV-2 infection has a detrimental effect on semen volume values ( < 0.

Impact of bariatric surgery on ovarian reserve markers and its correlation with nutritional parameters and adipokines.

Introduction: A reduction in anti-müllerian hormone (AMH) levels at short-term after bariatric surgery (BS) has been previously described. However, an assessment of ovarian reserve at longer-follow up, and a comprehensive evaluation of the potentially implicated factors has not been reported.

Design: Prospective cohort study.

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.

Endocrinological and ovarian histological investigations in assigned female at birth transgender people undergoing testosterone therapy.

Research Question: What are the hormonal and ovarian histological effects of a gender affirming hormonal therapy in assigned female at birth (AFAB) transgender people?

Design: Prospective observational study of 70 AFAB transgender people taking testosterone therapy before gender-affirming surgery (hystero-oophorectomy). A gynaecological ultrasonographic scan was undertaken and serum hormone concentrations measured, including anti-Müllerian hormone (AMH) and androgenic profile. Histological ovarian evaluation was assessed in both ovaries, including the developmental stages of the follicles.

Bariatric Surgery on Reproductive Outcomes: the Impact According to the Diagnosis of Polycystic Ovarian Syndrome and Surgical Procedures.

Background: There is limited evidence on the impact of bariatric surgery (BS) on reproductive outcomes in the general population and specifically in patients with polycystic ovarian syndrome (PCOS) or the effect of different BS techniques.

Purpose: The study aims to investigate the impact of BS on fertility, pregnancy, and newborn outcomes in reproductive age women who have undergone BS and the outcomes according to surgical procedure and PCOS diagnosis.

Materials And Methods: This was a retrospective, descriptive, cross-sectional study performed in women from 18-39 years undergoing BS in our centre from January 2005 to December 2010.
