Morbid obesity is associated with a large number of complications, including infertility; weight loss can help to improve fertility and increase the number of sperm in males. However, two of our patients developed azoospermia after bariatric surgery for weight reduction. A 30-year-old male presented to the outpatient department (OPD) with a BMI of 81.2 kg/m2 (258 kg) with no known co-morbidities. The patient had a normal sex life and one child. After bariatric surgery, he noticed a change in the consistency of his semen and azoospermia. In the second case, a 48-year-old man presented to the OPD with a BMI of 52 kg/m2 (189 kg) with no known co-morbidities. He had three children. He underwent bariatric surgery for weight loss and, after one year, he developed azoospermia. Bariatric surgery is a lifesaving procedure for morbidly obese patients and helps in restoring normal daily activities. This weight reduction surgery helps in decreasing blood pressure, increasing glycemic control and improving sexual activity. However, bariatric surgery may be followed by a further decline in semen parameters, resulting in azoospermia and severe oligoasthenoteratozoospermia. This is caused by the combined effects of two different processes: 1) the subduing of the negative effects of obesity, and 2) a deficiency of nutrients along with the release of some harmful substances. Bariatric surgery patients should be informed about the risk of complications and about the possibility for cryopreservation of sperm. In rare cases, bariatric surgery can result in a decrease in sperm count and infertility in males.
