One of the latest studies reveal those men who undergo weight loss surgery may suffer semen abnormalities as well as reduced fertility.
The study was conducted by a group of scientists from the Emory University School of Medicine in the US on a group who underwent Roux-en-Y gastric bypass (RYGB).
In gastric bypass surgery the stomach is segregated into small upper pouch and a much larger lower pouch. The small intestine is thereafter rearranged to connect both the pouches.
The scientists compared long-term effects among the group who were also sexually active and attempted to conceive with a partner.
Details of the study are published in the journal Bariatric Surgical Practice and Patient Care and it writes the vitamin D deficient and increased levels of the oestrogen hormone estradiol are the reasons to impact semen and fertility negatively.
Lead author Edward Lin said, “The study is one important piece in solving the puzzle of male infertility… The challenge is to see if correcting hormonal and micro-nutrient aberrations are enough to reverse male infertility.”
