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

open access: yesAndrology, 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.

Kisspeptin as a test of hypothalamic dysfunction in pubertal and reproductive disorders

open access: yesAndrology, EarlyView.
Abstract The hypothalamic–pituitary–gonadal axis is regulated by the gonadotropin‐releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and ...

Luteinizing hormone receptor knockout mouse: What has it taught us?

open access: yesAndrology, EarlyView.
Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...

These couples are often directly addressed to assisted reproduction techniques (ARTs).
