What are the major function of seminal plasma?

What contributes to seminal plasma?
Seminal plasma is a combination of secretions from the seminal vesicles, prostate, and bulbourethral glands. Not only does seminal plasma need to provide optimal pH and viscosity for sperm viability and motility, it must also provide a medium of fructose and various ions for spermatozoa to function.
Why do sperm contain mitochondria?
The sperm has to swim inside the female body in order to fertilize the egg but it needs a lot of energy to swim and fertilize the egg. Therefore, it has a large number of mitochondria which provide sperms with the large amounts of energy.
Which enzymes are present in seminal plasma?
To protect spermatozoa from oxidative stress, both spermatozoa and SP contain antioxidant enzymes known as superoxide dismutase (SOD), glutathione reductase (GR), glutathione peroxidases (GPx) and its substrates (GSH and GSSG), and catalase (CAT).
What are major components of seminal plasma 12?
The major components of the seminal plasma in the male reproductive system are mucus, spermatozoa, and various secretions of accessory glands. The seminal plasma is rich in fructose, calcium, ascorbic acid, and certain enzymes. It provides nourishment and protection to sperms.
What is the clear liquid that comes out before sperm?
