Final answer:
The Cowper's gland secretes a fluid that lubricates the urethra, neutralizes acid residue from urine, and may contain sperm, potentially leading to pregnancy without full ejaculation.
Step-by-step explanation:
The purpose of the drops of secretion from the Cowper's gland, also known as the bulbourethral gland, is to prepare the male urethra for ejaculation. This gland releases a clear, alkaline fluid that helps to lubricate the urethra, neutralize any acidic residues from urine, and may also play a role in cleaning urine residues from the penile urethra. This pre-ejaculate fluid, which is released when the male becomes sexually and shortly before the release of semen, can sometimes contain a few sperm, which means it has the potential to cause pregnancy even without full ejaculation.
