I do masturbation twice in a day. Does masturbation affects men's sperm count or does it cause infertility?

Masturbation, even when done frequently, does not have a significant or long-term impact on sperm count or male fertility. Here are some key points from the sources:

Temporary Reduction in Sperm Count

• Frequent ejaculation, whether through masturbation or sexual intercourse, can cause a temporary reduction in sperm count. However, this reduction is not permanent and does not affect overall fertility135.

Sperm Quality and Other Parameters

• Other sperm parameters such as motility and morphology remain unaffected by frequent masturbation. In fact, frequent ejaculation can help clear out older sperm and replace them with newer, healthier sperm134.

Optimal Abstinence and Fertility

• Optimum semen quality is often observed after 2-3 days of abstinence, but this does not mean that frequent masturbation is harmful. For those trying to conceive, having sex every 1-2 days during the fertile window is recommended, rather than abstaining from masturbation or ejaculation125.

Lifestyle and Health Factors

• Factors that can negatively affect sperm count and quality include varicoceles, infections, thyroid dysfunction, and lifestyle factors such as poor diet, lack of exercise, and exposure to toxic substances. Masturbation itself is not one of these factors34.

Mental Health and Balance

• While normal masturbation habits do not affect fertility, excessive or compulsive masturbation can be a sign of underlying mental health issues, which may indirectly affect overall well-being and fertility4.

In summary, masturbating twice a day is unlikely to cause any significant or long-term effects on sperm count or male fertility. Maintaining a healthy lifestyle and balance in sexual activities is more important for overall reproductive health.
