Ovary is to the female reproductive system as _______ is to the male reproductive system

Explanation

In the female reproductive system, the ovary plays an important role. It is responsible for producing eggs that can be fertilized by sperm to form a zygote, which eventually develops into a fetus. Now, the question is asking what structure in the male reproductive system is similar to the ovary in the female reproductive system. The correct answer is Option C: Testis. The testis is the male reproductive organ that produces sperm cells. Just like the ovary, it is a vital part of the reproductive system because it produces the gametes (sperm cells) that are necessary for fertilization. Option A (Penis) is incorrect as it is not an organ responsible for producing gametes like the testis and ovary. The penis is an external organ that serves as a conduit for urine and semen. Option B (Urethra) is also incorrect as it is a tube that carries urine and semen out of the body and does not produce gametes. Option D (Cowper's gland) and Option E (Prostate gland) are also incorrect as they are accessory glands that produce fluids that mix with sperm to form semen, but they do not produce gametes. In summary, the testis is similar to the ovary in the female reproductive system as they both produce gametes necessary for fertilization.
