Building families—Implementing balanced sexual and reproductive health

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract One of the main initiatives of the World Health Organization (WHO) is the promotion of Sexual and Reproductive Health (SRH). Sexuality, infertility, and contraception are three interconnected pillars of SRH, each essential for achieving global equity in family planning and family building.

Comparison of sperm retrieval and reproductive outcome in azoospermic men with testicular failure and obstructive azoospermia treated for infertility

Asian Journal of Andrology, 2014
We assessed the rates of sperm retrieval and intracytoplasmic sperm injection outcomes, including the neonatal profile of infants conceived, in men with testicular failure.

Factors Affecting Outcomes of Salvage Micro Testicular Sperm Extraction Following a Failed Testicular Sperm Extraction

Medical Bulletin of Haseki, 2020
Aim:To investigate the likelihood of sperm retrieval in repeated micro-testicular sperm extraction (micro-TESE) in non-obstructive azoospermia (NOA) patients.Methods:Data of 310 patients, who underwent a micro-TESE procedure at a center experienced in in vitro fertilization between January 2015 and July 2019, was evaluated retrospectively.

DUET‐seq: An Open‐Source Droplet Platform for High‐Fidelity Joint Chromatin and Transcriptome Profiling Reveals Temporal Regulatory Decoupling in Single Cells

Advanced Science, EarlyView.
DUET‐seq is an open‐source droplet platform that jointly profiles chromatin accessibility and gene expression from the same nucleus. Dissolvable dual‐linker hydrogel beads and a one‐step intra‐droplet RT‐PCR co‐index both modalities in under 12 h at roughly $0.04 per cell.

Testicular volume is a noninvasive predictor of sperm retrieval failure in idiopathic nonobstructive azoospermia

Asian Journal of Andrology
We investigated the prognostic importance of noninvasive factors in predicting sperm retrieval failure in idiopathic nonobstructive azoospermia (iNOA). We studied 193 patients with nonobstructive azoospermia who underwent microsurgical testicular sperm ...

WFS1 Deficiency Impairs PIAS4‐Associated SUMOylation and Increases Ubiquitin‐Mediated Spermatogenesis‐Related Protein Degradation Leading to Testicular Male Infertility

Advanced Science, EarlyView.
The findings establish a critical role for WFS1 in human male fertility. Mechanistically, WFS1 interacts with PIAS4 to promote the SUMOylation of key spermatogenesis‐associated proteins, which in turn competitively inhibits their K48‐linked ubiquitin‐mediated degradation during spermatogenesis.

Predictive factors shaping fertility potential and reproductive outcomes in men with Klinefelter syndrome

Asian Journal of Andrology
Klinefelter syndrome (KS), marked by testicular heterogeneity, provides a rationale for testicular sperm extraction in azoospermic men, yet large-scale evaluations of predictive and reproductive outcomes remain limited.

Laboratory handling of epididymal and testicular spermatozoa: What can be done to improve sperm injections outcome

Journal of Human Reproductive Sciences, 2012
Spermatozoa from azoospermic males can be retrieved from either the epididymis or the testis, depending on the type of azoospermia, using different surgical methods such as percutaneous epididymal sperm aspiration (PESA), testicular sperm aspiration ...

Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

The Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

Hormonal control and signaling of the testis of the bat Molossus molossus during the processes of testicular maturation, regression, and recrudescence

The Anatomical Record, EarlyView.
Abstract Molossus molossus, a species of neotropical bat belonging to the Molossidae family, has an annual reproductive cycle that includes two peaks of spermatogenic activity, one in April and another in September, and a period of total testicular regression in December.
