Weight-loss surgery could make men infertile, new research suggests.
Semen abnormalities occur in 57.1 per cent of men after having bariatric surgery, a study found.
Only four per cent of the study’s 79 participants fathered children after having the procedure, compared to 13 per cent before, the research adds.
Dr Edward Lin, editor-in-chief of the journal Bariatric Surgical Practice and Patient Care, which published the study, said: ‘This study is one important piece in solving the puzzle of male infertility.
‘The challenge is to see if correcting hormonal and micronutrient aberrations are enough to reverse male infertility.’
