In most species, there are just two types of gamete, and they are radically different. The egg is among the largest cells in an organism, while the sperm (spermatozoon, plural spermatozoa) is often the smallest.
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).
semen. a male reproductive cell; spermatozoon.
The word sperm is derived from the Greek word σπέρμα, sperma, meaning "seed".
(spurm) The male reproductive cell, formed in the testicle. A sperm unites with an egg to form an embryo.
Spermatozoa (sperm) are the male sex cells that carry a man's genetic material. They are so tiny that they can't be seen without a microscope. In a healthy man, one ejaculation usually contains between 40 million and 600 million sperm.
Pre-ejaculatory fluid is released from the male urethra in amounts of up to 4 ml during sexual arousal, prior to ejaculation. It is said to originate from Cowper's glands and the Glands of Littre, which open at different sites along the length of the urethra.
The white color of the semen is due to secretion from the prostate glands containing enzymes, citric acid, lipids, and acid phosphatase. This forms around 25-30% of the semen base.
Leaking semen when aroused or simply having sexual thoughts is normal for many young men. It can be a little messy and uncomfortable, but it doesn't indicate any sexual problems or other conditions on its own. Some semen may also leak out just prior to ejaculation or right afterward.
Answer. During sexual intercourse, most men ejaculate between 5-10 minutes and research has shown the average time to ejaculate after penetration is 5 1/2 minutes. Usually, ejaculation less than 1 to 1 1/2 minutes after penetration is regarded as premature ejaculation.
Spermarche—also known as semenarche—is the beginning of development of sperm in boys' testicles at puberty. It is the counterpart of menarche in girls. Depending on their upbringing, cultural differences, and prior sexual knowledge, boys may have different reactions to spermarche, ranging from fear to excitement.
There is no specific frequency with which a man should ejaculate. There is no solid evidence that failure to ejaculate causes health problems. However, ejaculating frequently can reduce the man's risk of getting prostate cancer. Ejacu-lation can be through having sex or masturbating a few times a day.
No, you can't run out of sperm. Your testes are always making new sperm, which means you'll have a constant supply even if you're masturbating a lot and/or having sex every single day. Having said that, it is possible to have a “dry orgasm”. This is where you reach a sexual climax, but don't ejaculate any semen.
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.
There are two types of sperm cells: X sperm and Y sperm. X sperm: X sperm on combining with the X chromosome of the female produces a zygote with XX chromosomes.
It takes just one sperm to fertilize a woman's egg. Keep in mind, though, for each sperm that reaches the egg, there are millions that don't. On average, each time men ejaculate they release nearly 100 million sperm.
However, some people who identify as women may produce sperm. If two women want to make a baby and one is cisgender and one is transgender (meaning they were assigned male at birth), there are several ways their sperm and eggs might meet, including through penetrative intercourse or ART.
Females possess remarkable abilities to select sperm to store and to fertilize their eggs that will make their offspring diverse.
Thick semen usually results from a higher than normal concentration of sperm in a typical volume of semen, or from having a high number of sperm with an irregular shape (morphology). High sperm concentration often indicates that you're more likely to impregnate a female partner.
A man might have watery semen if he doesn't get enough zinc in his diet. Zinc is an important nutrient for sperm production. Men who ejaculate several times a day might also develop watery semen, since the body needs time to “catch up” on its semen production.

Healthy semen is typically viscous, or jelly-like.
Healthy semen is a cloudy white color with a jelly consistency similar to a raw egg. Slight changes in semen color, texture, and even smell might be normal and should no pose concern. In some cases, semen color changes could be a sign of an underlying issue.
Clear semen typically refers to the pre-ejaculated fluid and white semen is part of the ejaculation. Clear semen may result in case of frequent ejaculation and may indicate low sperm count. White semen indicates less frequent ejaculations and is a thick and cloudy fluid.
