There is a lot of misinformation out there about male fertility and kidney health. Let's set the record straight: kidneys do not directly affect male fertility. However, kidney disease can indirectly impact fertility by causing hormonal imbalances or lowering testosterone levels. Additionally, certain medications used to treat kidney disease can reduce sperm count or motility. If you are experiencing any problems with fertility, it is important to speak with a doctor to rule out any underlying medical conditions.
