Causes of Infertility

In reviewing the medical literature and seeing patients who have been evaluated elsewhere, it is very difficult to get an accurate view of the underlying causes of infertility. Representative authorities each have a different view of what might be significant.2, 10-12 While it is generally stated that 30 percent of infertility problems will be related to a male factor problem, 30 percent to a female factor problem and 40 percent to a combination of the two, documentation of that is difficult to find and it appears to be mostly wishful politically-correct rhetoric.

In a review of the causes of infertility identified by various authorities, infertility was thought to be due to the male factor in a range of 6.2 to 30 percent. There were a multitude of causes found in women, including tubal factor, tubal/peritoneal factor, ovulatory dysfunction, endometriosis, diminished ovarian reserve, uterine/cervical factors, immunological factors, and unexplained reasons. But in some cases, ovulatory dysfunction was not identified as a cause and in other cases endometriosis was not identified. In most cases, endometriosis was seen to be a relatively infrequent cause of infertility.

In this same review, endometriosis was identified as the causative factor in 5, 5.6 and 25.8 percent of the patients, but endometriosis is extremely difficult to diagnose without laparoscopy. Laparoscopic evaluation in the infertile woman has been known for many years to provide a high yield of significant pelvic disease.13 Cervical factor was identified in a very small percentage of patients. Dr. M. Hull, in 1998, pointed out that cervical mucus defects and disorders are infrequent causes of infertility (three percent) and are difficult to diagnose with certainty. Furthermore, he pointed out that the most obvious defects result from cervical surgery, particularly conization of the lower cervical canal.3 This was echoed by the Boston IVF group7 who went on to say that “some women notice this change in the cervical mucus, whereas others do not,” implying that this information is not reliable or helpful. In this regard, the obvious following question would be: Why do some women not notice this change in the cervical mucus?
