Doctor's answer:

Normal semen appears milky white or light yellow. The average ejaculation volume for a healthy male is 2-6 milliliters, with an average of 3.5 ml. If there is prolonged infertility or excessive sexual activity, the semen may become thin and the color may become pale. At the same time, appropriate physical exercise should be carried out to enhance physical fitness. The diet should focus on tonifying the spleen and kidneys, such as yam, walnuts, and black foods. Semen can be extracted for testing. If it is normal, there is no major problem. Personal hygiene should be maintained.
