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. For patients with a history of endometriosis, pelvic infections, or ectopic pregnancy, evaluation with hysteroscopy or laparoscopy is recommended. CC is a nonsteroidal estrogen capable of interacting with estrogen receptor–binding proteins in a manner similar to estrogen but in a more prolonged way. [159, 160] Therefore, CC behaves similar to an antiestrogen. There are three main types of sperm antibodies: Immunoglobulin G (IgG) Immunoglobulin A (IgA) Immunoglobulin M(IgM).

Infection: Some infections, such as gonorrhea or inflammation of the testicles, can affect sperm production or sperm health or can cause scarring that blocks the passage of sperm. Known male factor semen abnormalities: If a male partner has a history of infertility with a prior partner, or if there are abnormalities on his semen analysis, then we advise earlier fertility evaluation, ideally within 6 months of attempting pregnancy.

They include: Clomifene (Clomid, Serophene): This encourages ovulation in those who ovulate either irregularly or not at all, because of PCOS or another disorder.

Human-beta defensin abnormalities Epididymis human-beta defensin is a protein that has been shown to have an important role in sperm maturation, and defects in it have been associated with decreased egg-penetrating ability.[27] One specific subtype, human-beta defensin-1 (HBD1), which has a wide distribution in various epithelia throughout the body and plays a role in antimicrobial activities against viruses, bacteria, and fungi, has also been investigated. In fact, endometriosis accounts for roughly 20 to 40 percent of women’s infertility issues.  Pain during sex: Painful sex for women is so normalized that many think it’s just a part of life.

Ovulation induction and intrauterine insemination are used after completion of the treatment in hopes of expediting the establishment of a pregnancy before relapse of the disease. [39, 157, 158] Treatment of Ovarian Factors Ovulation induction is the appropriate treatment for infertile patients who have dysfunction of the hypothalamic-pituitary-ovarian axis. The results of these tests help determine the best fertility treatment. Estimating the prevalence of infertility in Canada [published correction appears in Hum Reprod. Women receiving fertility treatment have a slightly higher risk of an ectopic pregnancy. Treatment[edit] Treatment depends on the cause of infertility, but may include counselling, fertility treatments, which include in vitro fertilization. ART techniques generally start with stimulating the ovaries to increase egg production.

The impact of fibroids located elsewhere in the uterus are controversial and do not always require surgery. Weight loss in obese infertile women results in improvement in reproductive outcome for all forms of fertility treatment.

Illegal drugs: Consumption of marijuana and cocaine can lower the sperm count. Allied and Complementary Medicine Database (AMED), ... Postcoital testing and antisperm antibody testing are no longer considered useful in this evaluation. Computer-aided semen analysis (CASA) Introduced in the late 1980s, CASA uses a video camera and computer to visualize and analyze sperm concentration and movement. As the amount of adipose tissue increases, there is more aromatase available to convert androgens, and serum estradiol levels increase.
