Patient's question:
Patient Age: 21Detailed Condition and Purpose of Consultation: I saw in a book that the man has a small amount of pre-ejaculate fluid leakage during erection. I'm wondering if it can cause pregnancy. I'm very worried! First Follow-up Question: There was sexual intercourse, but they used withdrawal method (coitus interruptus)!
Doctor's answer:
Hello:Fertilization is a complex physiological process that requires the following conditions: the ovary must release normal eggs, the semen must contain normally active sperm, the egg and sperm must meet in the fallopian tube and combine to form a zygote, which is then transported into the uterine cavity; the endometrium must be suitable for zygote implantation. If any of these conditions are abnormal, it can hinder fertilization, leading to infertility.
Modern reproductive medicine has elucidated that sperm from the male travels through the female vagina and uterus to reach the ampulla of the fallopian tube, where it meets the egg from the female ovary, which has traveled through the fimbriae of the fallopian tube. The sperm and egg combine to form a zygote, which then undergoes continuous division and travels through the fallopian tube to the uterus. It implants in the endometrium and continues to differentiate to form a fetus.
