Hi Dr, I am 32 years old single. Kindly let me know how to increase my semen volume. My semen quantity is getting less over the years. I don't masturbate frequently. I have nightfall 2/3 times every month. I noticed that when I get nightfall the quantity of sperm ejaculated in my underwear is less than when I had nightfall the years before. My semen volume was better between the age of 20-26. Kindly suggest good tips and natural ways to increase my sperm volume. Thanks for your answers.
