The question of whether prostate fluid and bulbourethral fluid can cause pregnancy is an interesting one and requires a nuanced understanding of human reproduction. To answer your question directly: while it is theoretically possible for these fluids to contribute to pregnancy, the likelihood is extremely low.

Prostate fluid and bulbourethral fluid are both components of semen, which is the fluid that carries sperm. Prostate fluid is produced by the prostate gland and makes up a significant portion of the semen, providing nutrients and a medium for sperm to swim. Bulbourethral fluid, produced by the bulbourethral glands (also known as Cowper's glands), is a pre-ejaculatory fluid that helps to lubricate the urethra and neutralize acidity in the urethra before ejaculation.

For pregnancy to occur, sperm must be deposited in the vagina, where it can travel through the cervix and into the uterus to fertilize an egg. The key factors in this process are the presence of viable sperm and the right conditions for fertilization. Here are some important points to consider:
1. Sperm Viability: Sperm must be alive and motile to fertilize an egg. Prostate and bulbourethral fluids can contain sperm, but the concentration and viability of sperm in these fluids can vary. Typically, the highest concentration of sperm is found in ejaculate during orgasm.

2. Exposure to Air and Environment: Sperm are sensitive to environmental conditions. Once exposed to air, sperm can quickly lose their motility and viability. If prostate or bulbourethral fluid comes into contact with the vaginal opening or underwear, the chances of sperm surviving long enough to cause pregnancy are significantly reduced.

3. Distance and Timing: For pregnancy to occur, sperm must be deposited close to the vaginal opening during the fertile window of the menstrual cycle. If prostate or bulbourethral fluid is merely touching the outer genitalia or clothing, the likelihood of sperm traveling through the vaginal canal and reaching the egg is minimal.

4. Pre-ejaculatory Fluid: It is worth noting that pre-ejaculatory fluid can sometimes contain sperm, especially if there has been a previous ejaculation. However, the concentration is generally much lower than in ejaculate.
5. Pregnancy Risk: While the risk of pregnancy from contact with prostate or bulbourethral fluid is low, it is not zero. If there is any concern about potential pregnancy, it is always advisable to use contraception to minimize the risk.

In summary, while prostate and bulbourethral fluids can theoretically lead to pregnancy if they come into contact with the vagina, the actual risk is very low due to factors such as sperm viability, environmental exposure, and the mechanics of reproduction. If you have further concerns about pregnancy risks or reproductive health, it is always best to consult with a healthcare professional for personalized advice and guidance.
