This mixture of semen then exits the penis during ejaculation. The spermatozoon is a remarkably complex metabolic, locomotive and genetic machine. It is approximately 60 microns in length and is divided into 3 sections: head, neck and tail.
The oval sperm head consists of a nucleus containing the highly compacted DNA, and an acrosome that contains the enzymes required for penetration of the egg shell for fertilization. The neck maintains the connection between the sperm head and tail and consists of the connecting piece and proximal centriole.
The tail harbors the midpiece, principle piece and endpiece. The tail midpiece contains the axoneme or engine of the sperm and the mitochondrial sheath, the source of energy for movement. Physiologically, the sperm axoneme is the true motor assembly and requires proteins to function. Among these, the microtubules are the best-understood components. Defects in the sperm axoneme are well-recognized causes of ciliary dyskinesias that are routinely associated with infertility.

A study examined the sperm counts of three males who abstained from ejaculating for several days before ejaculating four times at 2-hour intervals. The researchers found that their sperm counts dropped with frequent ejaculation but remained within World Health Organization WHO guidelines for healthy sperm counts. A study assessed the effects of frequent ejaculation on sperm quality and count.
Males who ejaculated daily saw declines in sperm count. Other measures of sperm quality — such as shape, ability to swim, and concentration — remained about the same, even with frequent ejaculation. Together, these studies suggest that in males with reduced fertility, frequent ejaculation might lower the chances of conception by lowering sperm count slightly.
Sperm work best at cool temperatures. The testicles help keep sperm cool by descending from the body. Prolonged exposure to heat — such as from hot tubs, intense exercise, or workplace equipment — may damage sperm. Males who want to improve fertility should wear loose fitting underwear.
Snug underwear may trap heat and force the testicles against the body, increasing temperature further. Anything that affects overall health may also affect sperm production, since sperm health depends on a complex interaction of several hormones and bodily systems.
For example, excessive drinking, drugs, and smoking may affect fertility. Exercise can improve blood flow and overall health, potentially improving sperm quality. Some studies suggest that getting regular exercise may improve sperm quality or count, though more research is needed to explain why.
It is also important to eat a healthful, balanced diet. Research has linked some foods with lower sperm health. These foods include processed meats, trans fats, soy products, and high fat dairy products.
However, most research has found only a correlation — not a causal relationship — between these foods and lower sperm counts. To improve the chances of conception, people can time when they have sexual intercourse to line up with when they are at their most fertile. Egg cells live for only 12—24 hours after ovulation , which means that timing sex for immediately before or after ovulation improves the chances of conception.
This fluid is produced during ejaculation by accessory glands: the seminal vesicles, the prostate, and the bulbourethral glands. The seminal vesicles, two saclike structures, sit close behind the bladder and extend toward the bladder. There they each join one of the vas deferens to form the ejaculatory ducts. The vesicles secrete a whitish-brown fluid containing sugars, prostaglandins, and other substances that makes up two-thirds of the semen volume.
The prostate, located under the bladder and above the start of the penis, contains the ejaculatory ducts and the prostatic urethra. As semen enters the urethra, the prostate secretes enzymes that help activate the sperm.
These glands add mucus that helps with sperm motility. The penis is part of the male external genitalia, suspended from the body at the front and sides of the pubic arch. Internally, the penis consists of three connected columns of tissue. The paired corpora cavernosa extend together from the root of the penis through the body.
The corpus spongiosum runs along the underside of the cavernosa. It contains the spongy urethra and expands past the body of the penis to form the glans penis the tip. Sperm release pathway.
What's this? Overview Sperm are produced and released by the male reproductive organs. Sperm production in the testes takes place in coiled structures called seminiferous tubules. Finally, the semen is ejaculated from the penis through the urethra.
