Effects of AZFc (b2/b4, b1/b3, b2/b3, and gr/gr) deletions and primary duplications on the outcomes of the first intracytoplasmic sperm injection treatment cycle: A single‐center retrospective cohort study

Andrology, EarlyView.
Abstract Background Current advances in high‐throughput sequencing technology enable the precise identification of Y chromosome microdeletion and primary duplication in infertile couples, but the mechanism and clinical significance of these mutations in assisted reproductive techniques remain unclear.

Evaluation of dimethandrolone undecanoate in non‐human primates as a candidate for long‐acting injectable male contraceptive

Andrology, EarlyView.
Abstract Background Dimethandrolone undecanoate (DMAU) is under development as a single agent hormonal male contraceptive. DMAU is a prodrug hydrolyzed by esterase(s) to the active metabolite dimethandrolone (DMA) which has dual androgenic and progestogenic actions.

A non‐hormonal reversible contraceptive targeting GSK3α, a protein kinase, essential for epididymal sperm maturation

Andrology, EarlyView.
Abstract Background and objectives Epididymal transit renders key competence to mammalian spermatozoa for fertilizing eggs. Generally, the two paralogs of glycogen synthase kinase 3, GSK3α and GSK3β, functionally overlap except in testis and sperm. We showed that GSK3α is essential for epididymal sperm maturation and fertilization.
