Fertility Evaluation: General and Sexual History A detailed history includes: General history  This includes occupation and background, use of tobacco, alcohol and drugs, earlier diseases, history of abdominal surgery and earlier infections. For women, being underweight and having extremely low amounts of body fat are associated with ovarian dysfunction and infertility and they have a higher risk for preterm birth. Hyperandrogenemic ovarian insufficiency is characterized by an immoderate production of androgen.

A small number of specimens have acceptable original concentrations of motile sperm but poor recoveries with the gradient system. Erectile dysfunction or premature ejaculation: Medication, behavioral approaches, or both may help improve fertility. Passive smoking has also been linked to lower fertility. Rather than a minimum 20 cm incision as in traditional (open) cholecystectomy, four incisions of 0. There may be testicular malformations, hormone imbalance, or blockage of the man's duct system. Studies have shown that approximately 70% of miscarriages are due to chromosomal abnormalities.

Then, generally one or two embryos, which have demonstrated appropriate development, are carefully and gently transferred into the uterine cavity. This averts normal ascension and motility of the sperm. 0.[44] Environmental factors Toxins such as glues, volatile organic solvents or silicones, physical agents, chemical dusts, and pesticides.[45][46] Tobacco smokers are 60% more likely to be infertile than non-smokers.[47] German scientists have reported that a virus called adeno-associated virus might have a role in male infertility,[48] though it is otherwise not harmful.[49] Other diseases such as chlamydia, and gonorrhea can also cause infertility, due to internal scarring (fallopian tube obstruction).[50][51][52] Alimentary habits[53] Obesity: The obesity epidemic has recently become is a serious issue, particularly in industrialized nations.

Primary Lymphoma of Kidney. (PDF, 586 KB) The Journal of Urology, 1973. It involves removing eggs from the ovary of a donor who has taken fertility drugs. Because of the action at the estrogen-receptor level within the hypothalamus, CC alleviates the negative feedback effect exerted by endogenous estrogens. [161, 162, 163] As a result, CC normalizes the GnRH release; therefore, the secretion of FSH and LH is capable of normalized follicular recruitment, selection, and development to reestablish the normal process of ovulation. [161, 164] The standard dose of CC is 50 mg PO qd for 5 days, starting on the menstrual cycle day 3-5 or after progestin-induced bleeding. As the major causes of infertility are sperm abnormalities, ovulation dysfunction, and fallopian tube obstruction, the preliminary adviced investigations for the infertile couple should be focused on semen analysis (to be compared with the WHO reference values [27]), detection of ovarian function by hormonal assay (early follicular FSH and LH levels, and mid-luteal progesterone), and evaluation of tubal patency by hysterosalpingography (HSG) [17-32], (Appendix 3). However, a survey has suggested that the 3 days most likely to offer a fertile window are the 2 days before ovulation plus the 1 day of ovulation. If the sperm are of good quality and the mechanics of the woman's reproductive structures are good (patent fallopian tubes, no adhesions or scarring), a course of ovulation induction maybe used.
