Posthumous sperm retrieval is a procedure in which spermatozoa are extracted from a man after he has been pronounced legally brain dead. Sperm retrieval from the penis has not been studied previously to the best of our knowledge. Our purpose was to determine the motility and viability of sperm from the penis with increasing time intervals from death. There was a progressive decrease in sperm motility with increasing post-mortem intervals, with a progressive increase in non-motility. Similarly, the sperm viability also showed a decreasing pattern with the increasing post-mortem interval. The sperm were found to be viable up to 24 h after death. Penile tract sperm retrieval has not been previously studied as far as we know.

Purpose: This study aimed to monitor the expression of B-cell translocation gene 2 (BTG2) in granulosa cells of patients undergoing IVF/ICSI with respect blastocyst quality outcomes.
Methods: We recruited 181 women undergoing IVF/ICSI cycles for infertility. Granulosa cells were extracted from follicular fluid.

Background: Transgender and gender diverse (TGD) people seek gender-affirming care at any age to manage gender identities or expressions that differ from their birth gender. Gender-affirming hormone treatment (GAHT) and gender-affirming surgery may alter reproductive function and/or anatomy, limiting future reproductive options to varying degrees, if individuals desire to either give birth or become a biological parent.
Objective And Rationale: TGD people increasingly pursue help for their reproductive questions, including fertility, fertility preservation, active desire for children, and future options.
Background: An estimated 17% of all couples worldwide are involuntarily childless (infertile). The clinically identifiable causes of infertility can be found in the male or female partner or in both. The molecular pathophysiology of infertility still remains unclear in many cases but is increasingly being revealed by genetic analyses.

Introduction: Hypospermatogenesis is a common histopathological subtype of non-obstructive azoospermia and is characterized by a decrease in the total number of germ cells within the seminiferous tubule as a result of spermatogenic failure. Determination of genetic factors before intracytoplasmic sperm injection can prevent the inheritance of these factors, as hypospermatogenesis patients gives high successful sperm retrieval rate. This study aimed to identify the structural variants associated with idiopathic hypospermatogenesis (iHS) by analyzing patient cohorts diagnosed with azoospermia using whole exome sequencing.

A 35-year-old man visited a local doctor for continuing analysis of his infertility. Semen analysis revealed azoospermia while an ultrasonography detected a right testicular tumor with a diameter of 10 mm. A blood test was negative for tumor markers.
