An abnormal semen analysis warrants a further evaluation usually by a reproductive urologist. A cumulative pregnancy rate of 80% is achieved during the first 6 cycles of therapeutic insemination. Some medications increase the risk of fertility problems in men. MESA or TESA? (PDF, 115 KB) Human Reproduction, 1996. Furthermore, as aging occurs, egg quality, or the likelihood of an egg being genetically normal, decreases.

Retrograde Ejaculation: Is a condition in which semen is ejaculated into the bladder rather than out through the urethra because the bladder sphincter does not close during ejaculation.  If this disorder is present, ejaculate volume is small and urine may be cloudy after ejaculation.  This condition affects 1. Coital frequency is positively correlated with pregnancy rates. Blockage of the ejaculatory duct: Sperm can be extracted directly from the testicles and injected into an egg in the laboratory. The woman may be given a low dose of ovary stimulating hormones. Individual tests evaluate only one aspect of a quality necessary for fertility and do not imply the ability or inability to achieve conception (see the Table in the Procedures section). Once a diagnosis has been made, you and your partner can consider the various treatment options.

If sperm does not appear in the ejaculate, but they are being produced, the doctor may be able to take sperm directly from the testicles, or from the bladder (in cases of retrograde ejaculation), and use that sperm to fertilize an egg in the lab. A high serum estradiol level (greater than 60 to 80 pg per mL [220 to 294 pmol per L]) in conjunction with a normal FSH level has also been associated with lower pregnancy rates. Over one million cholecystectomies are performed in the U. The optimum fertile period is around 23 years of age when only 5% of women have issues getting pregnant. 50% are female causes with 25% being due to anovulation and 25% tubal problems/other.[74] In Sweden, approximately 10% of couples wanting children are infertile.[75] In approximately one third of these cases the man is the factor, in one third the woman is the factor, and in the remaining third the infertility is a product of factors on both parts.

Assisted conception The following methods are currently available for assisted conception. It's used to remove polyps and fibroid tumors, divide scar tissue, and open up blocked tubes. 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.

Microsurgical Solutions to Male Infertility. (PDF, 2 MB) Contemporary OB/GYN, 2005. Algorithm for infertility evaluation. (ART = assisted reproductive technology.) Lifestyle Factors Jump to section + All couples should be counseled to abstain from tobacco use, limit alcohol consumption, and aim for a body mass index less than 30 kg per m2 to improve their chances of natural conception or using assisted reproductive technology. This seems to result in a significant improvement in fertility, although some studies disagree. A subgroup of patients has PCOS with hyperinsulinism, hyperandrogenism associated with acanthosis nigricans, and resistance to CC. [205, 206] This group is amenable to metformin treatment. [207, 208] Metformin improves insulin sensitivity and decreases hepatic gluconeogenesis and, therefore, reduces hyperinsulinism, basal and stimulated LH levels, and free testosterone concentration. Role of Epididymis in Sperm Maturation. (PDF, 3 MB) Urology, 1989. Some men respond with an increase in testosterone levels; many also recover normal sperm counts. A low testosterone level with a low FSH level signals a secondary cause. Treatment of the cause: 28. Tubal and uterine factors: 4. 8 A high serum FSH level (greater than 30 to 40 mIU per mL [30 to 40 IU per L]) with a low estradiol level can distinguish ovarian failure from hypothalamic pituitary failure, which typically reveals a low or normal FSH level (less than 10 mIU per mL [10 IU per L]) and a low estradiol level. Less common factors The following other factors may also be responsible for infertility in a smaller proportion of cases: • Genetic abnormalities within eggs, sperm or both • An abnormal uterine cavity, including the presence of fibroids or polyps • Immunological infertility, whereby either the male or female partner produces anti-bodies against sperm cells or implantation of an embryo • Abnormal cervical mucus which hinders the passage of sperm to the uterus and fallopian tubes Unexplained infertility Even when investigations have been extensive, some couples will have no reason with which to explain their infertility. Normal Fertilization of Human Oocytes after Testicular Sperm Extraction and Intracytoplasmic Sperm Injection.(PDF, 2 MB) Fertility and Sterility, 1994. Some diseases: Conditions that are sometimes linked to lower fertility in males are anemia, Cushing's syndrome, diabetes, and thyroid disease. Patients present with oligospermia but have LH levels within the reference range. Key to the diagnosis of male infertility is a semen analysis, which assesses primarily sperm numbers, sperm movement and sperm form.
