The effectiveness of condoms as a contraceptive method and the probability of pregnancy?

Your girlfriend's menstrual cycle is approximately 28 days, with her last period occurring from December 18 to December 24.
Overall, her menstrual cycle is relatively regular, with occasional delays of about 1-3 days.
She is unsure if her period lasts exactly 7 days, but it is generally around 6-8 days.
We engaged in sexual intercourse on December 26 and 27, using condoms throughout.
However, after manually stimulating my penis, she did not wash her hands before putting on the condom for intercourse.
Additionally, I may have touched her clitoris or inserted my fingers into her vagina before touching my penis.
According to the menstrual tracking app, December 30 seems to be her ovulation day, with the fertile window from December 25 to January 3.
Therefore, I have three questions:
1.
If both partners engage in manual stimulation without washing hands, and then touch the female's clitoris or vagina, or handle the condom before intercourse, is it possible for sperm from pre-ejaculatory fluid or prostatic fluid to cause pregnancy?
2.
Given this scenario, what is the likelihood of the female becoming pregnant? Should she take emergency contraception?
3.
If there are no plans for pregnancy, what precautions should be taken when using condoms for contraception, especially during the fertile window or ovulation days? For example, to avoid sperm in pre-ejaculatory fluid or prostatic fluid leading to pregnancy, should we be particularly careful during manual stimulation, or wash hands before putting on a condom? Additionally, during the fertile window, even with a condom, should we withdraw before ejaculation? Thank you, Dr.

Hello, the questioner: There is a possibility of pregnancy even if ejaculation does not occur during intercourse, as pre-ejaculatory fluid may contain sperm.
As long as there are active sperm in the vagina during the ovulation period, there is a chance of conception regardless of the method of intercourse.
The failure rate of using condoms as a contraceptive method is over 5%, which is less reliable compared to other methods.
It is generally not recommended to rely solely on condoms for contraception.
It is advisable to consider emergency contraception as an additional measure, although its effectiveness is not 100%, with a failure rate of about 3%.
I still recommend that you take appropriate contraceptive measures, and if necessary, consult a physician for evaluation.
Thank you! Wishing you peace and health.

When discussing the effectiveness of condoms as a contraceptive method and the associated risks of pregnancy, it is essential to consider several factors, including the proper use of condoms, the timing of sexual activity in relation to the menstrual cycle, and the potential for sperm transfer through manual stimulation.

1. Sperm Transfer Risk: In your scenario, you mentioned that after manual stimulation of your penis, you did not wash your hands before putting on the condom. This raises a valid concern about the potential transfer of sperm from your hands to the condom. While the likelihood of pregnancy from this situation is relatively low, it is not impossible. Pre-ejaculatory fluid (pre-cum) can contain sperm, and if any sperm were present on your hands, there is a slight risk of transferring it to the condom. However, the amount of sperm in pre-cum is typically much lower than in ejaculate, and the risk of pregnancy from this transfer is minimal.

2. Pregnancy Probability: Given that you used condoms consistently during intercourse, the risk of pregnancy is significantly reduced. Condoms are approximately 85% effective with typical use, meaning that while there is a chance of failure, it is relatively low when used correctly. Since your girlfriend's ovulation period was around December 30, and you had intercourse on December 26 and 27, you were indeed within her fertile window. However, the use of condoms provides a barrier that greatly reduces the likelihood of sperm reaching the egg. If you are concerned about the risk of pregnancy, it may be worth considering emergency contraception, especially if you feel that there was a significant risk of sperm transfer.

3. Condom Use and Precautions: To enhance the effectiveness of condoms as a contraceptive method, especially during the fertile window, consider the following precautions:
- Hand Hygiene: Always wash your hands before touching the condom or engaging in sexual activity after manual stimulation. This minimizes the risk of transferring any sperm that may be present on your hands.

- Proper Condom Application: Ensure that the condom is applied correctly and that there is no air trapped at the tip, which can cause breakage.

- Withdrawal Method: If you are particularly concerned about the risk of pregnancy, consider using the withdrawal method (pulling out) before ejaculation, in addition to using condoms. However, this method should not be relied upon solely as it requires significant self-control and timing.

- Check for Damage: Before and after use, check the condom for any signs of damage or breakage. If a condom breaks during intercourse, consider using emergency contraception if within the appropriate time frame.

- Regular Use: Consistently using condoms for all sexual encounters is crucial. Avoid using oil-based lubricants with latex condoms, as they can degrade the material and increase the risk of breakage.

In summary, while the risk of pregnancy in your situation is low due to the use of condoms, it is essential to be aware of the potential for sperm transfer through manual stimulation. Practicing good hygiene, using condoms correctly, and being mindful of the timing of sexual activity in relation to the menstrual cycle can further reduce the risk of unintended pregnancy. If there are any concerns about potential pregnancy, consulting with a healthcare provider for advice on emergency contraception and further reproductive health guidance is recommended.
