Is it safe to have sex on the 14th day of the menstrual cycle?

Patient's question:

No

Doctor's answer:

There are approximately 3 million sperm at the tip of an erect penis. If no contraceptive measures are taken, a woman's ovulation can be affected by external factors, climate, her own emotions, and health status, leading to delayed or early ovulation, and even extra ovulation. This can easily result in pregnancy. It is best to take contraceptive measures, such as oral emergency contraception.
