Question

The nutritive medium for the ejaculated sperms is given by

• A. Seminal fluid
• B. Vaginal fluid
• C. Uterine lining
• D. Fallopian tube

Answer 1

The correct option is A

Seminal fluid

The correct option is A.

Explanation of the correct option:

1. Semen(seminal fluid) is made up of secretions from the epididymis, seminal vesicles, prostate, and bulbourethral gland, as well as sperm. Only 1% of sperm is present in semen.
2. The remaining is a fluid secretion from accessory glands that provides fructose to nourish sperm as well as an alkaline medium to neutralize urethral (urinary) and vaginal acidity and a liquid medium for sperm motility.

Explanation of the incorrect options:

Option B:

1. Vaginal discharge is a clear or white fluid that flows out of the vaginal canal and protects the vaginal area against infection.

Option C:

1. The uterine lining is the uterus's inner wall. During the menstrual cycle, it goes through various changes.
2. It thickens in order to receive the zygote formed post-fertilization so that it gets enough nutrition to grow.
3. But if fertilization does not occur, it sheds, resulting in menstrual blood loss.

Option D:

1. Oviducts, also known as fallopian tubes, are tubes that connect each ovary to the uterus on either side of the female reproductive system.
2. The fertilization takes place in the fallopian tubes.

Final answer: The nutritive medium for the ejaculated sperms is given by seminal fluid.
