1. Seminal Fluid Production: Seminal glands are responsible for the majority of seminal fluid production. This fluid constitutes about 60-70% of the total semen volume.
2. Nutrient Provision: Seminal fluid contains various nutrients that are essential for sperm health and function. These include fructose, which serves as an energy source for sperm, as well as amino acids, proteins, enzymes, and vitamins.
3. Alkalinization of Semen: Seminal fluid has a slightly alkaline pH, which helps neutralize the acidic environment of the vagina. This alkaline pH creates a more favorable environment for sperm survival and motility.
4. Sperm Protection: Seminal fluid contains substances that protect sperm from various harmful factors. These substances include antioxidants, which neutralize free radicals that can damage sperm, and antimicrobial peptides, which help protect sperm from infection.
5. Coagulation and Liquefaction: Seminal fluid undergoes two important changes after ejaculation. Initially, it coagulates into a semi-solid form, which prevents the immediate loss of semen from the female reproductive tract. This coagulated state is temporary, and the seminal fluid subsequently liquefies, allowing for the release and movement of sperm.
6. Prostaglandin Production: Seminal glands contribute to the production of prostaglandins, hormone-like substances that play a role in female reproductive processes. Prostaglandins can influence uterine contractions and cervical dilation during labor.
It's important to note that the seminal glands work in conjunction with other accessory glands, such as the prostate gland and bulbourethral glands (Cowper's glands), to contribute to the overall composition and function of semen. Together, these glands provide a suitable environment for sperm survival and transport, enhancing the probability of successful fertilization and reproduction.
