If a tube is blocked and filled with fluid (called a hydrosalpinx), then minimally invasive surgery (laparoscopy or hysteroscopy) to either remove the tube or block/separate it from the uterus prior to any fertility treatments is recommended. As new technology becomes available, fertility treatment is now accessible to more people, and success rates and safety are improving all the time. Ovulation occurs about two weeks before a woman’s next period starts.

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. For example, endometriosis can cause infertility with the growth of endometrial tissue in the Fallopian tubes or around the ovaries. Possible problems could be that the egg is not released at the optimum time for fertilization, that it may not enter the fallopian tube, sperm may not be able to reach the egg, fertilization may fail to occur, transport of the zygote may be disturbed, or implantation fails. Abnormal semen may not be able to carry the sperm effectively. Patients with a grade 1-3 varicocele (visible or palpable) associated with infertility should consider having the varicocele repaired.

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. The likelihood of fertilization improves significantly for men with low sperm concentrations. Vasectomy. (PDF, 5 MB) From the Encyclopedia of Reproduction, 1999.
