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. This prevents the sperm from fertilizing the egg. Embryo Development after ICSI Using Testicular, Epididymal and Ejaculated Spermatozoa. (PDF, 2 MB) Frontiers in Endocrinology, 1995.

The easiest and most successful treatment is intrauterine insemination (IUI). [104] Similar treatments apply when oligospermia, hypospermia, and ejaculatory disorders such as impotence, hypospadias, or retrograde ejaculation are present. [105, 106, 107] Patients with azoospermia that is not amenable to in vitro fertilization/intracytoplasmic sperm injection treatment benefit from artificial insemination (AI) with donor sperm. [108] Artificial insemination can be performed by depositing the sperm at the cervical level (cervical insemination) [106] or inside the endometrial cavity (intrauterine insemination).
