What is male sperm called?

The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat).

What Is Reproduction?

Reproduction is the process by which organisms make more organisms like themselves. But even though the reproductive system is essential to keeping a species alive, unlike other body systems, it's not essential to keeping an individual alive. In the human reproductive process, two kinds of sex cells, or gametes (GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat). The zygote goes through a process of becoming an embryo and developing into a fetus. The male reproductive system and the female reproductive system both are needed for reproduction. Humans, like other organisms, pass some characteristics of themselves to the next generation. We do this through our genes, the special carriers of human traits. The genes that parents pass along are what make their children similar to others in their family, but also what make each child unique. These genes come from the male's sperm and the female's egg.

What Is the Male Reproductive System?

The male has reproductive organs, or genitals, that are both inside and outside the pelvis. The male genitals include:

the testicles (TESS-tih-kulz)

the duct system, which is made up of the epididymis and the vas deferens

the accessory glands, which include the seminal vesicles and prostate gland

the penis

In a guy who has reached sexual maturity, the two oval-shaped testicles, or testes (TESS-teez) make and store millions of tiny sperm cells. The testicles are also part of the endocrine system because they make hormones, including testosterone (tess-TOSS-tuh-rone). Testosterone is a major part of puberty in boys, and as a guy makes his way through puberty, his testicles produce more and more of it. Testosterone is the hormone that causes boys to develop deeper voices, bigger muscles, and body and facial hair. It also stimulates the production of sperm. Alongside the testicles are the epididymis and the vas deferens, which transport sperm. The epididymis (ep-uh-DID-uh-miss) and the testicles hang in a pouch-like structure outside the pelvis called the scrotum. This bag of skin helps to regulate the temperature of testicles, which need to be kept cooler than body temperature to produce sperm. The scrotum changes size to maintain the right temperature. When the body is cold, the scrotum shrinks and becomes tighter to hold in body heat. When it's warm, it gets larger and floppier to get rid of extra heat. This happens without a guy ever having to think about it. The brain and the nervous system give the scrotum the cue to change size. The accessory glands, including the seminal vesicles and the prostate gland, provide fluids that lubricate the duct system and nourish the sperm. The urethra is the channel that carries the sperm (in fluid called semen) to the outside of the body through the penis. The urethra is also part of the urinary system because it is also the channel through which pee passes as it leaves the bladder and exits the body. The penis is actually made up of two parts: the shaft and the glans. The shaft is the main part of the penis and the glans is the tip (sometimes called the head). At the end of the glans is a small slit or opening, which is where semen and urine exit the body through the urethra (yoo-REE-thruh). The inside of the penis is made of a spongy tissue that can expand and contract.

Why would a man have low testosterone?

Testosterone is a hormone made by the testicles. It is important for a man's sex drive and physical appearance. Certain health conditions, medicines, or injury can lead to low testosterone (low-T). Testosterone level also naturally drops with age.

medlineplus.gov - Could you have low testosterone?: MedlinePlus Medical Encyclopedia

Your provider will likely have you get a blood test to check your testosterone level. You will also be checked for other causes of your symptoms. These include medicine side effects, thyroid problems, or depression. If you have low testosterone, hormone therapy may help. The medicine used is man-made testosterone. This treatment is called testosterone replacement therapy, or TRT. TRT can be given as a pill, gel, patch, injection, or implant. TRT may relieve or improve symptoms in some men. It may help keep bones and muscles strong. TRT seems to be more effective in young men with very low testosterone levels. TRT can also be helpful for older men.

TRT has risks. These may include:

Infertility

Enlarged prostate leading to difficulty urinating

Blood clots

Worsening heart failure

Sleep problems

Cholesterol problems

At this time, it is unclear whether TRT increases the risk of heart attack, stroke, or prostate cancer. Talk with your provider about whether TRT is right for you. If you do not notice any change in symptoms after treatment for 3 months, it is less likely that TRT treatment will benefit you. If you decide to start TRT, be sure to see your provider for regular checkups.
