Semen
Updated:Semen, also known as seminal fluid, is a whitish or yellowish fluid produced by the male reproductive system. It's primarily released during ejaculation and typically contains sperm cells, which are crucial for reproduction. Semen is a complex mixture of fluids from various glands, including the testicles, seminal vesicles, prostate, and bulbourethral glands.
Additional Information
The average volume of semen released during ejaculation is about 2-5 milliliters, though this can vary. While sperm cells make up only about 1-5% of semen's volume, the rest consists of various components that nourish and protect the sperm. These include fructose (for energy), zinc (for sperm health), and alkaline compounds (to neutralize the acidic environment of the vagina).
Semen plays a crucial role in fertility, but it's important to note that pre-ejaculate (pre-cum) can also contain sperm and potentially lead to pregnancy. Additionally, some sexually transmitted infections (STIs) can be transmitted through semen, highlighting the importance of safe sex practices.
Examples
During sexual intercourse, semen is typically ejaculated into the vagina, where sperm can then travel to potentially fertilize an egg.
In fertility clinics, semen samples are often analyzed to assess sperm count, motility, and overall quality.
