Experts warn 'hidden steroids' in protein shakes may damage male fertility

The rising popularity of protein supplements for muscle growth has prompted medical experts to warn of potential risks to male reproductive health.

While protein is fundamental for hormone synthesis and cellular repair, the indiscriminate use of processed powders can be detrimental.

Dr Kshitiz Murdia, CEO of Indira IVF Hospital Limited, notes that supplements contaminated with added steroids or heavy metals can significantly decrease sperm count and harm overall sperm health.

Common contaminants such as stanozolol and methandienone not only interfere with natural testosterone production but can also lead to liver damage.

"Male fertility is influenced by several interconnected factors, including hormonal balance, metabolic health, nutritional adequacy, stress levels, and lifestyle habits," Dr Murdia explained to Health Shots.

He emphasised that while spermatogenesis is an energy-intensive process, most men can meet their requirements through a balanced diet of pulses, dairy, and lean meats without needing supplementation.

Critical factors affecting sperm quality

Hormonal disruption occurs when products contain undeclared anabolic steroids that interfere with signals necessary for sperm formation.

Furthermore, an overreliance on supplements at the expense of antioxidants can lead to oxidative stress, which is "associated with sperm DNA damage and reduced sperm function," according to Dr Murdia.

Recommendations for safe consumption

• Foundation of diet: Men should prioritise whole food sources over processed shakes to maintain metabolic stability.
• Product transparency: Supplements must be sourced from reputable manufacturers that provide third-party testing for heavy metals.
• Physiological limits: Intake should remain between 1.0 and 1.6 grams per kilogram of body weight, as exceeding this confers no additional fertility benefits.

Ultimately, maintaining a healthy weight and managing stress exert a more substantial influence on fertility than supplementation alone.
