Seminal plasma is the fluid portion of semen that surrounds sperm cells during ejaculation. Although sperm represent the reproductive cells responsible for fertilization, the composition of seminal plasma is equally important for successful reproduction.
This fluid contains proteins, enzymes, sugars, minerals, and hormones that support sperm function. One of the key components is fructose, which provides energy for sperm motility as they travel through the female reproductive tract.
Seminal plasma also contains antioxidants that protect sperm from oxidative damage. Without these protective substances, erotic sperm cells may experience structural damage that impairs their ability to fertilize an egg.
Abnormalities in seminal plasma composition may contribute to fertility disorders such as Teratozoospermia, which involves abnormal sperm morphology.
Laboratory evaluation of semen can provide valuable information about both sperm cells and the surrounding seminal plasma environment.
