Longitudinal Analysis of Male Fertility Using an Acr-Luc Knock-In Mouse Model: A Preclinical Platform for Reproductive Toxicity Testing. [PDF]

open access: yesMedComm (2020)
This study presents an Acr‐Luc knock‐in mouse model that enables longitudinal visualization of spermatogenesis using bioluminescence imaging. By combining a germ cell‐specific promoter with luciferase reporting, the system captures real‐time suppression and recovery of male reproductive function after toxic exposures.

Mouse genome engineering uncovers 18 genes dispensable for male reproduction

open access: yesAndrology, EarlyView.
Abstract Background Male infertility is an intricate multifactorial disease involving the interplay between genetic and environmental factors. Genetic anomalies account for more than 15% of all male infertility cases; however, diagnosing them exhibits enormous challenges due to variable symptomatic presentations and limited knowledge of gene functions.

Genetics of infertility and “assisted fertilization” in the Bible: The case of Abraham and his family

open access: yesAndrology, EarlyView.
Abstract Couple infertility is a very ancient medical condition. One of the first descriptions of familial infertility/subfertility is contained in the first book of the Bible, Genesis, written in the 10th century BC and reporting tales from the oral tradition even occurred about 800 years earlier.

Development of a nomogram for sperm retrieval at microTESE for idiopathic non‐obstructive azoospermia in a multi‐center cohort study

open access: yesAndrology, EarlyView.
Abstract Background Non‐obstructive azoospermia (NOA) affects approximately 10% of infertile men and represents a major challenge in assisted reproductive technology (ART). A model that includes histological variants could be helpful in predicting sperm retrieval rate (SRR) after microdissection testicular sperm extraction (mTESE) in patients affected ...

Lactate inhibits glucose‐induced zigzag motility and enhances linear motility in bull spermatozoa by suppressing glycolysis

open access: yesAndrology, EarlyView.
Abstract Background Energy metabolism and substrate balance are critical determinants of sperm motility and fertility. Linear motility is necessary for sperm forward movement, whereas hyperactivated motility is a prerequisite for fertilization. The preference of metabolic pathways depends on substrate availability which controls sperm motility. However,
