Although the links between celiac disease and infertility in women are fairly well established, much less research exists on the link between celiac disease and male infertility. From the scant research that has been done, it appears that there may be a link between celiac disease and male infertility. Just as with women who suffer from the disease, men who have undiagnosed celiac disease seem to suffer from infertility more often than other men. However, not all studies show such a clear link, so more research is needed before doctors can say definitively that celiac disease lowers male fertility and whether a gluten-free diet can help with the condition. Men with undiagnosed celiac disease appear to have a much higher rate of abnormal semen, along with abnormal hormone levels. Specifically, a study found that more than 19% of men with celiac disease suffered from infertility during their marriage, and semen analyzes found problems with sperm structure and ability to move. In addition, another study found that men with undiagnosed celiac disease are more likely to suffer from androgen resistance, meaning their bodies do not respond properly to the male hormone testosterone. According to research, androgen resistance reflects an overall disruption of the male endocrine system caused by celiac disease. Studies on celiac disease and male infertility have found that sperm characteristics improved after participating men were diagnosed with celiac disease and went on a gluten-free diet. These studies also found that hormone levels returned to normal after the men started a gluten-free diet. Therefore, it is possible for men with celiac disease who previously suffered from infertility to recover after starting a gluten-free diet, which is often the case for women with celiac disease. Most of the studies on fertility in men with celiac disease were done in the 1970s and 1980s, indicating a great need for updated information. References: 1. Verywell Health.
