Patient's question:
Males produce sperm during sexual activity, and when sperm combines with an egg cell, it forms a fertilized egg that then develops into an embryo. What color is it when it dries on underwear?Doctor's answer:
After women enter puberty, their lower body is always wet. Their underwear is no longer clean, either with transparent and colorless secretions or with cheesy white secretions. Sometimes they are slightly yellow, bloody, or brown. Although they usually have no odor, if the external genital area is not washed and underwear is not changed for a day or two, the odor becomes unpleasant. This is due to the influence of estrogen, which is secreted in large quantities after the ovaries develop. In medicine, this is called leukorrhea.
