Sexually transmitted infections (STIs): Chlamydia can damage the fallopian tubes in a woman and cause inflammation in a man's scrotum. Practice Committee of American Society for Reproductive Medicine in collaboration with Society for Reproductive Endocrinology and Infertility. Treatment of tubal obstruction generally requires referral for subspecialty care.

Human menopausal gonadotropins Crowe discovered that the gonads were under the control of the anterior hypophysis. [175] Zondek and Aschheim discovered that FSH and LH were responsible for the development of the gonads in immature animals and confirmed Crowe's work. [135, 136] In the 1930s, ovulation induction was attempted by using gonadotropins from a mare, but its use was discontinued because of the development of antibodies. [176, 177] Borth et al demonstrated the effect of FSH and LH extracted from menopausal urine. [178, 179] Gemzell reported the first ovulation induction using human pituitary gonadotropin in 1958, and the first pregnancy was reported in 1960. [180, 181] Lunenfeld reported preliminary results using hMG; however, in 1963, it was definitely established as a real ovulation induction agent. [182, 183, 184] Human menopausal gonadotropin (hMG [eg, Repronex, Menopur]) contains 75 U of FSH and 75 U of LH per mL, although the concentration may vary among batches (ranges from FSH at 60-90 U and LH at 60-120 U). Continued For some men, no male infertility treatments seem to help. New Concepts in Operative Andrology: A Review. (PDF, 7 MB) International Journal of Andrology, 2000. Counseling about options should be offered to couples who are not physically able to conceive (i.e., same-sex couples or persons lacking reproductive organs). The sediment is suspended in a buffer solution, and the recovered sperm is processed using the sperm-wash technique before it can be used for intrauterine insemination. If a woman can get pregnant but keeps having miscarriages or stillbirths, that's also called infertility.

Infertility rates have increased by 4% since the 1980s, mostly from problems with fecundity due to an increase in age.[72] Fertility problems affect one in seven couples in the UK. Ovulation disorders About one quarter of infertility cases are due to ovulation disorders. The most common technique of artificial insemination in human beings is intrauterine insemination. Spermiogenic defects may also be a cause of sterility. If the correction is not done, it may be harder for the sperm to get to the female's cervix.

Treatment of tubal obstruction generally requires referral for subspecialty care. After stimulation, the physician surgically extracts one or more eggs from the ovary, and unites them with sperm in a laboratory setting, with the intent of producing one or more embryos. Other medical techniques are e.g. tuboplasty, assisted hatching, and preimplantation genetic diagnosis. However, a woman who does not ovulate at each menstrual cycle is not necessarily going through menopause. Laparoscopic and thoracoscopic surgery belong to the broader field of endoscopy. 22 Treatment of Male Infertility Jump to section + Underlying etiology determines the therapeutic course, although male infertility is unexplained in 40% to 50% of cases. 1 Among couples 15 to 44 years of age, nearly 7 million have used infertility services at some point. If conception does not occur after many months or years of trying, it can lead to stress and possibly depression. Factors Affecting Fertility: Timing of Intercourse Intercourse prior to ovulation is key to maximizing the chance of pregnancy. The predictable pregnancy rate for this group is about 5% after timed intercourse, 10% after superovulation with intrauterine insemination (IUI), and 15% to 25% after assisted reproduction techniques (ART) [41]. The dynamics of stress in fertile and infertile couples. 34 Although intrauterine insemination has been shown to be equally effective as timed intercourse in unstimulated cycles, there is a modest increase in live birth rates when combined with ovarian stimulation.
