Patient's question:
A 34-year-old woman, her body has been feeling uncomfortable gradually, and she doesn't know what's wrong. It seems like she lacks energy. Please ask: the principles and necessary conditions for pregnancyDoctor's answer:
Conception requires the simultaneous presence of two conditions: one is that the woman is within her ovulation period, and the other is that sperm enters the vagina. How the penis enters the vagina is not the key; the key is how sperm enters the vagina. If ejaculation occurs at the vaginal opening, even if the hymen is still intact and there is no actual sexual intercourse, but if the woman is within her ovulation period, it is best not to have intercourse during her ovulation period. For most women, ovulation occurs 12 to 16 days before the next menstrual period, making this period the time of highest fertility. Contraceptive methods such as condoms and oral contraceptives can be used.
