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. A doctor injects sperm directly into the egg in a dish and then places it into your uterus. Fertility treatment with donor eggs is usually done using IVF. Genetic tests can identify specific obstacles to fertility and problems with sperm. The typical indication is the oligoasthenoteratozoospermia here.
If conception does not occur after many months or years of trying, it can lead to stress and possibly depression. However, about one in five cases of infertility has no clear diagnosed cause.[73] In Britain, male factor infertility accounts for 25% of infertile couples, while 25% remain unexplained.

Pain during sex Some women have experienced painful sex their entire lives, so they’ve convinced themselves it’s normal. Three regions have been described, called azoospermic factors a, b, and c (AZFa, AZFb, AZFc).[24] These deletions are observed in 3-19% of patients with idiopathic infertility and 6-14% of patients with oligospermia, although up to 7% of patients with other known causes of infertility may also be found to have a deletion.

No Differences in Outcome after Intracytoplasmic Sperm Injection with Fresh or with Frozen-thawed Epididymal Spermatozoa. (PDF, 66 KB) Human Reproduction, 1999. Chemotherapy: Some chemotherapy drugs can result in ovarian failure. Undescended testicles During fetal development one or both testicles may fail to descend from the abdomen into the sac that normally contains the testicles. CI or intrauterine insemination is the treatment of choice if more than 2 million sperm are recovered after the sperm wash. (See Treatment of Cervical Factors). [106, 109] Patients whose reproductive tract, FSH, LH, and testosterone levels are determined to be normal or those who have low testosterone in the absence of any other hormonal abnormalities can be treated empirically with cycles of CC (25 mg PO qd for at least 6-12 mo).

Hypogonadism Hypogonadism is an abnormally low level of testosterone, the male sex hormone involved in making sperm. If it stays in there, complications can develop, such as the rupture of the fallopian tube. Assisted Reproductive Technology: Using Ejaculated, Fresh, and Frozen-thawed Epididymal and Testicular Spermatozoa Gives Rise to Comparable Results after Intracytoplasmic Sperm Injection. (PDF, 5 MB) Fertility and Sterility, 1995. If a cause for your fertility problems hasn't been identified, talk to your doctor about the next steps. In 1985, Erich Mühe performed the first laparoscopic cholecystectomy. Guidelines and recommendations were retrieved from the best evidence reviews at the American College of Obstetricians and Gynaecologists (ACOG), American Society for Reproductive Medicine (ASRM), Canadian Fertility and Andrology Society (CFAS), European Society of Human Reproduction and Embryology (ESHRE), Human Fertilisation and Embryology Authority (HFEA), Royal College of Obstetricians and Gynaecologists (RCOG), and the World Health Organization (WHO). Affected individuals displayed more severe forms of infertility such as azoospermia and severe oligozoospermia.[27] Other causes[edit] Factors that can cause male as well as female infertility are: DNA damage DNA damage reduces fertility in female ovocytes, as caused by smoking,[28] other xenobiotic DNA damaging agents (such as radiation or chemotherapy)[29] or accumulation of the oxidative DNA damage 8-hydroxy-deoxyguanosine[30] DNA damage reduces fertility in male sperm, as caused by oxidative DNA damage,[31] smoking,[28] other xenobiotic DNA damaging agents (such as drugs or chemotherapy)[32] or other DNA damaging agents including reactive oxygen species, fever or high testicular temperature.[33] The damaged DNA related to infertility manifests itself by the increased susceptibility to denaturation inducible by heat or acid [34] or by the presence of double-strand breaks that can be detected by the TUNEL assay.[35] General factors Diabetes mellitus,[36][37] thyroid disorders,[38] undiagnosed and untreated coeliac disease,[39][40][41][42] adrenal disease[43] Hypothalamic-pituitary factors Hyperprolactinemia Hypopituitarism The presence of anti-thyroid antibodies is associated with an increased risk of unexplained subfertility with an odds ratio of 1.
