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.

Human asthenozoospermia: Update on genetic causes, patient management, and clinical strategies
Abstract Background In mammals, sperm fertilization potential relies on efficient progression within the female genital tract to reach and fertilize the oocyte. This fundamental property is supported by the flagellum, an evolutionarily conserved organelle, which contains dynein motor proteins that provide the mechanical force for sperm propulsion and ...

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.

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

Abstract Background In infertile couples whose male partner has alterations in semen parameters frequently, a comprehensive andrological approach is lacking and approximately 30–50% are classified as idiopathic infertility. These couples are often directly addressed to assisted reproduction techniques (ARTs).

Abstract Background Cryopreservation of human semen is the cornerstone for preserving male fertility before gonadotoxic therapy or in cases of high variability in semen parameters. This is particular crucial in cases of severe oligoasthenoteratozoospermia (OAT), where diminished sperm counts may compromise planned intracytoplasmic sperm injection (ICSI)
