Mullerian Duct in Male Rabbit

The Mullerian duct is a paired embryonic duct that exists in both male and female embryos. In females, it develops into the oviducts, uterus, and upper portion of the vagina. In males, it degenerates due to the presence of anti-Mullerian hormone (AMH) secreted by the testes. However, in some cases, the Mullerian duct may persist and result in the formation of abnormal reproductive structures.

In the male rabbit, the Mullerian duct develops into the seminal vesicle. The seminal vesicle is a glandular structure that produces and secretes seminal fluid, which is an important component of semen.

Options Explained:

a) Prostatic Utricle: The prostatic utricle is a small blind pouch that exists in the male reproductive system. It is formed from the Mullerian duct and is present in some male mammals, including humans. However, it is not present in rabbits.

b) Seminal Vesicle: As mentioned earlier, the seminal vesicle develops from the Mullerian duct in male rabbits. It is an important glandular structure that produces and secretes seminal fluid.

c) Cowpers Gland: The Cowpers gland, also known as the bulbourethral gland, is a glandular structure present in the male reproductive system. It produces and secretes a clear fluid that contributes to the lubrication of the urethra during sexual arousal. However, it is not formed from the Mullerian duct and is therefore not the correct answer.

d) Urethra: The urethra is a tube that carries urine and semen out of the body. It is present in both male and female reproductive systems. However, it is not formed from the Mullerian duct and is therefore not the correct answer.

Conclusion:

In conclusion, the correct answer to the given question is option 'B', Seminal Vesicle, as it is the reproductive structure that develops from the Mullerian duct in male rabbits.
