Women who experience very heavy, painful periods may be showing signs of endometriosis, a condition where tissues usually found in the womb are present elsewhere in the body. To help objectify sperm morphology and therefore enhance the consistency and reproducibility among laboratories, Kruger introduced a definition of "strict criteria" in 1986. This is where no cause can be identified in either the woman or man. 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. Alternatively, the patient may bypass surgical treatment and proceed directly to intrauterine insemination or in vitro fertilization, depending on the severity and the female partner's age.

Make an appointment with your doctor and go over your concerns. 7 million women reported impaired ability to get pregnant or carry a baby to term.

BMI (body mass index) may be a significant factor in fertility, as an increase in BMI in the male by as little as three units can be associated with infertility. Programming of Ovarian Stimulation with Norethindrone Acetate in IVF/GIFT Cycles. (PDF, 2 MB) Human Reproduction, 1989. 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. The starting dose is 5 mcg per pulse intravenously or 5-25 mcg subcutaneously. The impact of fibroids located elsewhere in the uterus are controversial and do not always require surgery. The prevalence varies widely, being less in developed countries and more in developing countries where limited resources for investigation and treatment are available [2]. Ovulation-inducing drugs and ovarian cancer risk: results from an extended follow-up of a large United States infertility cohort. Couples who do not conceive after treatment for six cycles with documented ovulation should also consider referral to an infertility specialist.
