Associated conditions[edit] For most women, alteration of menstrual periods is the principal indication of chronic anovulation. Tests and trials are available, but testing does not always reveal a specific cause. 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 applies to the ability to conceive with her eggs, but not with donor eggs.

IVF involves removal of eggs directly from the ovary, fertilization with sperm in the laboratory, followed by transfer of the embryos directly into the uterus, thereby bypassing the tubes. Myoma treatment In general, small and asymptomatic myomas do not require treatment, but the patient should be periodically monitored. There may be testicular malformations, hormone imbalance, or blockage of the man's duct system.

Congenital forms of anestrus may be due to lack of function of the hypothalamic-pituitary axis or ovarian dysgenesis. Adverse effects of metformin include GI intolerance, nausea, vomiting, and abdominal cramps. However, for certain very poor specimens with low original concentrations of motile sperm, the use of the gradient system results in such a negligible recovery as to render it useless. Progesterone deficiency can be corrected by the administration of progesterone during the luteal phase, starting 48 hours after ovulation. [204] Patients with hyperprolactinemia need a thorough evaluation to exclude a pituitary microadenoma. Semen and sperm Sometimes the sperm cannot travel effectively to meet the egg. A karyotype test and a Y chromosome test for microdeletions are indicated in patients with nonobstructive azoospermia or severe oligospermia (< 5 million sperm/mL), although indications are expanding.[20] Klinefelter syndrome Klinefelter syndrome is the most common chromosomal cause of male infertility, estimated to be present in 1 per 500-1000 male births.

Requirements for Female Fertility (Continued) Other requirements for female fertility include: Adequate sexual drive and sexual function to permit coitus. IVF in action Intracytoplasmic sperm injection (ICSI): A single sperm is injected into an egg to achieve fertilization during an IVF procedure. As an antiestrogen, CC requires that the patient have some circulating estrogen levels; otherwise, the patient will not respond to the treatment. Women 35 and older should see their doctor after six months of trying. A review of systems and physical examination of the endocrine and gynecologic systems should be performed.
