Question

In male cockroaches, sperms are stored in which part of the reproductive system?

• A. Mushroom glands
• B. Testes
• C. Seminal vesicles
• D. Vas deferens

Answer 1

Answer: (C)

1. Testes lie dorsolaterally in the 4th and 5th abdominal segments, and they are the region of sperm production.

2. Vas deferens are a pair of ducts arising from the testis as very thin whitish tubes, they continue posterioventrally beneath the rectum. They unite at a short distance into the ejaculatory duct.

3. Mushroom gland is a large accessory reproductive gland, whitish in colour and situated at the junction of vasa deferentia with the ejaculatory duct. It has a mass of glandular tubules of two kinds; utriculi majores and utriculi breviores.

4. The sperms produced from testes, while the cockroach is still young, are brought by the vasa deferentia into the seminal vesicles for storage. The sperms in the seminal vesicles are glued together in the form of bundles called spermatophores.

So, the correct option is 'Seminal vesicles'.
