The Effect of Assisted Reproductive Technologies on Human Sex Ratios
ABSTRACT Background Modern assisted reproductive technology (ART), including pre‐implantation genetic testing for aneuploidy (PGT‐A), has opened new avenues in understanding early embryonic events and has simultaneously raised questions about the impact of ART itself on sex ratios.

Genomic technologies and the diagnosis of 46, XY differences of sex development
Abstract Differences/disorders of sex development can be caused by disruptions to the molecular and cellular mechanisms that control development and sex determination of the reproductive organs with 1:100 live births affected. Multiple genes are associated with 46, XY differences/disorders of sex development that can cause varying clinical phenotypes ...

Abstract Background Ascorbic acid 2‐glucoside (AA2G) is a stabilized form of ascorbic acid and a potent antioxidant. Ascorbic acid is present in the testes and epididymis and helps maintain the physiological integrity of reproductive organs. Its properties have been utilized to protect spermatozoa of different species from oxidative stress.

Inhibition of ROS1 activity with lorlatinib reversibly suppresses fertility in male mice
Abstract Background Inhibition of sperm maturation in the epididymis is a promising post‐testicular strategy for short‐acting male contraceptives. It has been shown that ROS1, a receptor tyrosine kinase expressed in the epididymis, is essential for epididymal differentiation, sperm maturation, and male fertility in mice.
