Association of higher serum follicle-stimulating hormone levels with successful microdissection testicular sperm extraction outcomes in nonobstructive azoospermic men with reduced testicular volumes

Asian Journal of Andrology
To investigate the impact of preoperative serum follicle-stimulating hormone (FSH) levels on the probability of testicular sperm retrieval, we conducted a study of nonobstructive azoospermic (NOA) men with different testicular volumes (TVs) who underwent

Multi‐Tissue Genetic Regulation of RNA Editing in Pigs

Advanced Science, EarlyView.
This study presents the first multi‐tissue map of RNA editing and its genetic regulation in pigs. By integrating RNA editing profiles, edQTL mapping, GWAS, and cross‐species comparisons, this work establishes RNA editing as a distinct regulatory layer linking genetic variation to complex traits, highlighting its functional and evolutionary significance.

Updates on sperm retrieval techniques.

Translational andrology and urology, 2014
In the most extreme form of male infertility, the male partner is azoospermic. The advent of in vitro fertilization (IVF)-intracytoplasmic sperm injection (ICSI) has revolutionized our ability to treat azoospermia in both obstructive and non-obstructive cases.

Spontaneous uterine rupture after myomectomy in patients during pregnancy: Clinical cases in a single university center

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Uterine rupture is an infrequent yet sometimes fatal complication of a subsequent vaginal birth attempt following a previous uterine surgery. We have chosen to write about spontaneous uterine ruptures following myomectomy due to the scarcity of data on this subject, stemming from the limited number of reported cases.
