Sperm4
- The bulbourethral glands are responsible for producing a pre-ejaculate fluid called Cowper's fluid (known colloquially as pre-cum), which is secreted during sexual arousal, neutralizing the acidity of the urethra in preparation for the passage of sperm cells. (wikipedia.org)
- According to one preliminary study, the bulbourethral gland fluid might not contain any sperm, whereas another study showed some men did leak sperm in potentially significant quantities (in a range from low counts up to 50 million sperm per ml) into the pre-ejaculatory fluid, potentially leading to conception from the introduction of pre-ejaculate. (wikipedia.org)
- However, the sperm source is a residual or pre-ejaculatory leak from the testicles into the vas deferens, rather than from the bulbourethral gland itself. (wikipedia.org)
