Assertion (A): Seminal vesicles produce fluid Reason (R): For the nourishment of sperms
The fluid from the seminal vesicles is viscous and contains fructose, which provides an energy source for the sperm; prostaglandins, which contribute to the mobility and viability of the sperm; and proteins that cause slight coagulation reactions in the semen after ejaculation.
Seminal vesicles are the glands producing nutritional fluid for the sperm once they have matured in the seminiferous tubule.
Explanation:
Seminal vesicles are the glands producing nutritional fluid for the sperm once they have matured in the seminiferous tubule.
The Seminal Vesicles are present above the bulbourethral glands. It is made of three layers:
- Outer, connective tissue
- Middle smooth muscle tissue
- Inner layer, producing the fluid
They produce and store the nutritional fluid which with sperm is called, the semen.
This fluid is rich in fructose, providing energy for the sperm to swim through. Phosphorus and Potassium facilitate movement of sperm. It also contains an alkaline fluid which neutralizes the acidic conditions of male urethra and the vaginal canal.
70% of the contents of the semen are of the fluid produced by the seminal vesicles. The smooth muscles of the middle layer contract and secrete the fluid into the tract when ejaculation is to happen.
