Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.

The testes are responsible for making testosterone, the primary male sex hormone, and for generating sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubes are responsible for producing sperm cells.

Sperm develop in the testicles within a system of tiny tubes called the seminiferous tubules. At birth, these tubules contain simple round cells. During puberty, testosterone and other hormones cause these cells to transform into sperm cells.

Sperm, also called spermatozoon, plural spermatozoa, male reproductive cell, produced by most animals. Mature sperm have two distinguishable parts, a head and a tail.

Guys start producing spermatozoa (or sperm, for short) at the onset of puberty. Puberty starts at different times for different people. Boys usually start puberty when they’re around 10 or 12 years old, though some start a little sooner and others a little later.

One is called the urethra. It is hollow and carries urine from the bladder through the penis to the outside. The semen travels through the urethra and comes out the end of your penis.

Urinating after sex helps cleanse the urethra from harmful bacteria. According to Dweck, the biggest benefit of urinating after sexual intercourse is that it helps reduce the chances of getting a urinary tract infection.

Parekh. It happens when the edges of the urethra get temporarily stuck together. The urethra is the tube that carries urine (and also semen, in men) out of the body. This sticky situation is often caused by dry ejaculate that doesn’t fully exit the urethra, gumming up the pipes.

Five foods to avoid that may decrease sperm health and male fertility

• Processed meats. This is not surprising—recent studies link processed meats to all sorts of illnesses.
• Trans fats.
• Soy products.
• Pesticides and bisphenol a (BPA)
• High fat dairy products.
• Fish.
• Fruits and veggies.
• Walnuts.

Frequent male masturbation isn’t likely to have much effect on your fertility. Some data shows that optimum semen quality occurs after two to three days of no ejaculation. But other research suggests that men who have normal sperm quality maintain normal sperm motility and concentrations even with daily ejaculation.

According to a study done in Human Reproduction in 2013, excess consumption of cheese and full fat milk may impact sperm count. Dairy products do add protein and essential nutrients required by the body but full fat dairy products, especially cheese and full fat milk should be avoided.

Spermicides are birth control medicine that kill sperm. There are many kinds of spermicides: cream, foam, jelly, suppository or film. How do I use it? Spermicide (in any form) is placed deep inside the vagina and works by killing sperm that touches it before the sperm can reach an egg.

Home sperm tests require ejaculation into a collection cup. While procedures vary for transferring semen and completing the test, results are typically available within a few minutes. The tests work by detecting a protein found only in sperm.

What’s the best way to produce healthy sperm?

1. Maintain a healthy weight. Some research suggests that increasing body mass index (BMI) is linked with decreasing sperm count and sperm movement.
2. Eat a healthy diet.
3. Prevent sexually transmitted infections (STIs).
4. Manage stress.
5. Get moving.

As long as the ejaculate wasn’t inside your body or on your vagina, you can’t get pregnant. Ejaculate on the outside of your body isn’t a pregnancy risk. But if your partner ejaculates near your vagina and then fingers you, they may push some of the semen into your vagina. If this happens, pregnancy is possible.

It’s possible for you to get pregnant without having sexual intercourse if, for example: sperm get into your vagina – for example, if you or your partner have semen or pre-ejaculate on your fingers and touch your vagina.
