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

Andrology, 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?

Andrology, 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 ...

Gut‐Derived Exosomes Mediate the Microbiota Dysbiosis‐Induced Spermatogenesis Impairment by Targeting Meioc in Mice

Advanced Science
Diseases like obesity and intestinal inflammation diseases are accompanied by dysbiosis of the gut microbiota (DSGM), which leads to various complications, including systemic metabolic disorders.

Comprehensive diagnostic and therapeutic approach to male factor infertility aimed at natural fertility: A multicentric retrospective cohort study

Andrology, EarlyView.
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).

Transcriptome sequencing reveals the characteristics of spermatogenesis and testis development in Amphioctopus fangsiao

Aquaculture Reports
Spermatogenesis is the production of spermatozoa by the testes, a process that is associated with reproduction in males. Amphioctopus fangsiao is an economically important species from the northern coast of China, and little research has been done on ...

The use of deidentified organ donor testes for research

Andrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...
