Part 4/5:
As sperm travel through the reproductive tract, they encounter seminal vesicles where they are mixed with seminal fluid. This fluid not only provides crucial nutrients but also serves as a medium for the sperm, facilitating their transport outside the body during ejaculation.
In the urethra, prostatic fluid is added to the semen. The prostate gland's contractions play a significant role in preventing urine from mixing with semen, ensuring a safe and effective delivery of sperm. These contractions also help propel the semen out of the body during ejaculation.
