Obesity-related subfertility is an increasingly recognized concern. Pharmacotherapies (particularly glucagon-like peptide 1 receptor agonists and combination therapies), alongside lifestyle intervention, enable meaningful and sustainable weight loss in people with and without type 2 diabetes mellitus. Weight loss can benefit sperm parameters, but the optimal amount and rate of weight loss requires further study.
