On Regenerating the Ovary and Generating Controversy. (PDF, 37 KB) Cell, 2005. Hormonal Problems A small percentage of male infertility is caused by hormonal problems. The hypothalamus-pituitary endocrine system regulates the chain of hormonal events that enables testes to produce and effectively disseminate sperm. Several things can go wrong with the hypothalamus-pituitary endocrine system: · The brain can fail to release gonadotrophic-releasing hormone (GnRH) properly. GnRH stimulates the hormonal pathway that causes testosterone synthesis and sperm production. A disruption in GnRH release leads to a lack of testosterone and a cessation in sperm production. · The pituitary can fail to produce enough lutenizing hormone (LH) and follicle stimulating hormone (FSH) to stimulate the testes and testosterone/sperm production. LH and FSH are intermediates in the hormonal pathway responsible for testosterone and sperm production. · The testes� Leydig cells may not produce testosterone in response to LH stimulation. · A male may produce other hormones and chemical compounds which interfere with the sex-hormone balance. Antibodies that attack sperm Anti-sperm antibodies are immune system cells that mistakenly identify sperm as harmful invaders and attempt to eliminate them.
