PMID 7988065. There is now substantial evidence that coeliac sprue is associated with infertility both in men and women. (...) In men it can cause hypogonadism, immature secondary sex characteristics and reduce semen quality. (...) Hyperprolactinaemia is seen in 25% of coeliac patients, which causes impotence and loss of libido. Gluten withdrawal and correction of deficient dietary elements can lead to a return of fertility both in men and women.
Fertility has long been considered a “woman’s problem.” This is simply not true, and men are in fact, equally as infertile as women. Traditionally the metrics for male fertility have been mostly limited to sperm count, morphology, motility, and, occasionally, DNA fragmentation. For females, on the other hand, a vast array of tests are available. These include ultrasound, cervical position, basal body temperature, hysteroscopy, laparoscopy, cycle tracking and a diversity of hormonal tests.
Only 30 percent of patients who receive 100 mg of Clomiphene a day will produce more than three follicles. Patients that produce less than than three follicles have about half the chance of getting pregnant than those that produce greater than three follicles. Patients that receive fertility medications but do not do an insemination have only half the success rates compared to those who do.
