Maternal age Infertility due to age is one of the most common causes of female infertility. The Treatment of Azoospermia with Surgery and ICSI. (PDF, 4 MB) Chapter 10 from Male Fertility & Infertility, 1998. Cervical stenosis (a narrowed cervix) or the lack of cervical mucus often make it harder for sperm to travel through the cervix into the uterus. Microscopic Technique for Reversal of Vasectomy. (PDF, 3 MB) Surgery, gynecology & obstetrics, 1976. Some personal habits are considered risk factors for infertility, such as excess alcohol intake [11] and cigarette smoking [12]. Illegal drugs: Consumption of marijuana and cocaine can lower the sperm count.

There may be testicular malformations, hormone imbalance, or blockage of the man's duct system. 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). Functional sperm that are present may have a normal karyotype. The authors of the new global standards said the revised definition gave every individual “the right to reproduce.” Until now, the WHO’s definition of infertility—which it classed as a disability—has been the failure to achieve pregnancy after 12 months or more of regular unprotected sex. A Modern View of Male Infertility. (PDF, 7 MB) From The Infertile Male: Advanced Assisted Reproductive Technology, 1994. 0 The reflection of malformations, dysplasia or hypoplasia of the uterus is possible with hysterosalpingoscopy.

Microsurgery in Clinical Urology. (PDF, 5 MB) Urology, 1975. Intercourse 2 or 3 times per week may be considered average, although the frequency varies. This procedure is done by ultrasound guidance when the surgeon utilizes a narrow needle to retrieve eggs from the ovary through the vaginal wall. For in-vitro fertilization, a 100,000 of sperm are necessary and, for the intracytoplasmatic sperm injection, only a few sperms are required.

Gonadotrophins for idiopathic male factor subfertility. With laparoscopy providing tissue diagnosis, and helping to achieve the final diagnosis without any significant complication and less operative time, it can be safely concluded that diagnostic laparoscopy is a safe, quick, and effective adjunct to non‑surgical diagnostic modalities, for establishing a conclusive diagnosis, but whether it will replace imaging studies as a primary modality for diagnosis needs more evidence.[34] History[edit] Hans Christian Jacobaeus It is difficult to credit one individual with the pioneering of the laparoscopic approach. According to ESHRE recommendations, couples with an estimated live birth rate of 40% or higher per year are encouraged to continue aiming for a spontaneous pregnancy.[66] Treatment methods for infertility may be grouped as medical or complementary and alternative treatments. Vasoepididymostomy to the Head of the Epididymis: Recovery of Normal Spermatozoal Motility. (PDF, 3 MB)Fertility and Sterility, 1980.

37 Clomiphene has also proven effective for ovulation induction in women with polycystic ovary syndrome. Rarely, a blood clot may develop in an artery or vein, liver or kidney problems can arise, and respiratory distress may develop. The starting dose is 5 mcg per pulse intravenously or 5-25 mcg subcutaneously. 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. Through this technique, your physician can diagnose abnormalities such as fibroids or polyps within the uterine cavity, and via narrow instruments that run through the hysterosope, can remove or correct the great majority of these abnormalities.
