In men who have the necessary reproductive organs to procreate, infertility can be caused by low sperm count due to endocrine problems, drugs, radiation, or infection. When this is not the case, a couple facing male infertility may turn to a sperm donor or adoption to help build their family. Thankfully, even when the cause of infertility is not known, various fertility treatments can eventually lead to delivery of a healthy baby. Known uterine fibroids or endometrial polyps: Uterine abnormalities, such as fibroids that indent the endometrial cavity and endometrial polyps, can impair how the endometrium (the lining of the uterus) and embryo interact to lower implantation and pregnancy rates.

2 This encompasses couples with infertility and impaired ability to get pregnant, but it does not capture those who are not married, so actual numbers may be underestimated.

Obesity may also lead to less frequent ovulation or to less frequent intercourse, thereby contributing to fertility problems. In one study,  treatment with recombinant HBD1 in asthenozoospermic and leukocytospermic patients who were deficient in HBD1 resulted in improved bactericidal activity and sperm quality, which supports this protein’s role in fertility and its potential role in managing infertility.[28] Other causes Causes of testicular failure also include the following: Granulomatous disease – Leprosy and sarcoidosis may infiltrate the testicle Sickle cell disease – Sickling of cells within the testis leads to microinfarcts Excessive use of alcohol, cigarettes, caffeine, or marijuana Despite a thorough workup, nearly 25% of men have no discernible cause for their infertility. Radiation therapy: If this is aimed near the reproductive organs, it can increase the risk of fertility problems. It is often prescribed for Crohn's disease or rheumatoid arthritis. The patient should receive prophylactic antibiotics and uterine relaxants (eg, ibuprofen) during these 7 days to prevent infection and balloon expulsion, respectively.
