Patient's question:
Detailed medical condition and consultation purpose: I had my period on 05/10/15, and had sexual intercourse on 05/11/14, but it was standing-up external ejaculation. I haven't had my period yet. Am I pregnant? I'm so scared. What should I do? First follow-up question: I've always been regular, usually coming two to three days early each month. This time, it's delayed. If it's not pregnancy, should I just wait and see? I'm afraid of the hospital. Thank you!Doctor's answer:
The previously secreted fluid also contains a large number of sperm. To determine whether the fertility of both partners is strong, if they are both in their teens or early twenties and it is the ovulation period, pregnancy is entirely possible.The failure rate of withdrawal ejaculation as a contraceptive method is over 90%. According to Guo Zhaohu, a urologist from Beijing Shuguang Hospital, there are three main reasons for the failure of withdrawal ejaculation as a contraceptive method:
First, during sexual activity, as sexual excitement increases, various glands in the male reproductive system become more active, and secretion fluid along with some seminal vesicle fluid may leak out of the urethral opening before ejaculation and enter the female reproductive tract. This fluid contains a certain number of sperm cells.
Second, many men fail to accurately time ejaculation, and withdrawing the penis from the vagina too late can easily leave semen in the vagina or at the vaginal opening.
Third, semen left around the female vaginal opening, on the male penis, or in other areas may enter the female reproductive tract due to other possible reasons.
