Patient's question:
Detailed medical condition and consultation purpose: There is also another question, which is that after intercourse, semen always flows out completely. What is the reason for this? How is it caused! Thank you. I look forward to the experts answering my question.Doctor's answer:
Hello: Since the anterior and posterior walls of the vagina are normally close together and the internal cavity space is not large, the vagina expands to a certain extent during intercourse, and it returns to normal quickly after intercourse. The vagina cannot accommodate a large amount of liquid. The average amount of semen expelled by a man per ejaculation is 4 to 6 milliliters, and it is initially semi-fluid with a gel-like consistency. After intercourse, some semen may flow out when the penis is withdrawn, but not all of it. The remaining semen accumulates in the posterior fornix of the vagina, where the cervix is immersed. Sperm enters the vagina through the external opening of the cervix, and this does not affect fertility.
