Can You Get Pregnant After Masturbation and Unprotected Sex?

If you masturbate and then have unprotected sex three hours later, there is a possibility of pregnancy if sperm is present. If you then use a condom after some time, the risk of pregnancy would depend on whether sperm was still viable and if the condom was used correctly. It's important to remember that sperm can live inside the female reproductive tract for several days, so if unprotected intercourse occurs, there is a risk of pregnancy?

If I masturbated at 9:30 PM and then had sexual intercourse with my girlfriend at 12:30 AM, first without a condom and then using a condom for ejaculation, is there a possibility of residual sperm in the ejaculatory duct after masturbation? Could this lead to pregnancy?

When it comes to the question of whether you can get pregnant after masturbation and then engaging in unprotected sex, there are several factors to consider regarding sperm retention and the likelihood of pregnancy.

Firstly, after ejaculation during masturbation, it is possible for some sperm to remain in the urethra. The urethra is the tube that carries urine from the bladder and semen from the reproductive system out of the body. If you masturbate and then engage in sexual intercourse shortly afterward, there may be residual sperm left in the urethra. This is particularly relevant if you do not urinate between the two activities, as urination can help flush out any remaining sperm.

In your scenario, you mentioned that you masturbated at 21:30 and then had sexual intercourse at 00:30. This two-hour gap may allow for some residual sperm to remain in the urethra, especially if you did not urinate in between. When you initially engaged in sex without a condom, there is a risk that any remaining sperm could potentially lead to pregnancy if they were deposited in the vaginal canal.

However, the use of a condom during the latter part of the sexual encounter significantly reduces the risk of pregnancy. Condoms are designed to prevent sperm from entering the vagina, thus providing a barrier that can effectively prevent pregnancy when used correctly. If the condom was intact and used properly during ejaculation, the likelihood of pregnancy is greatly diminished.

To summarize, while there is a possibility of residual sperm remaining in the urethra after masturbation, the risk of pregnancy is significantly reduced if a condom is used correctly during sexual intercourse. If you are concerned about the possibility of pregnancy, it is advisable to consider emergency contraception if the unprotected intercourse occurred within the last 72 hours, as this can further reduce the risk of pregnancy.

Moreover, it is important to consider sexually transmitted infections (STIs) when engaging in unprotected sex. If you have any concerns about STIs or potential pregnancy, it is wise to consult with a healthcare professional for appropriate testing and guidance.

In conclusion, while there is a theoretical risk of pregnancy due to residual sperm after masturbation, the use of a condom during sexual intercourse greatly reduces this risk. Always practice safe sex to protect against both unintended pregnancies and STIs.
