Men aren't born with ready-made sperm cells - they have to be made later, from puberty onwards. (Interestingly, when females are born they already have all their quota of eggs.) Spermatozoa are made in vessels, within the testicles, called seminiferous tubules.
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.
The epididymis is the tube which moves the sperm from the testicles. Vas deferens. This is a tube in which the sperm is stored and it carries the sperm out of the scrotal sac.
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.
Studies show that the average length of time that sperm live, once ejaculated or inserted into the female reproductive system, is around three days. This depends on where she is in her menstrual cycle, however—with just the right timing, stronger sperm could last up to five days.
Boys begin to have wet dreams when they reach puberty, usually between the ages of 9 and 15.
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.
How many times can a man ejaculate in a day? Some men can ejaculate more times during the day than others. Younger men tend to ejaculate more often than their older counterparts. Some men can ejaculate (or come) once or twice a day, whereas some guys can do it four or five times.
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.
After sex. After orgasm, every man goes through a recovery cycle, called the refractory period, which is when it is not possible to get another erection. This resolution stage can take anything from minutes to days and varies from man to man, generally extending as you get older.
Wet dreams are normal, though not everyone has them. Many boys also experience spontaneous erections during puberty. Again, it's normal if they do, and normal if they don't.
Children whose sleep is disturbed by snoring, television or pets, and children who are deep sleepers are more likely to wet the bed. Stress or life changes. Going through big changes like moving or a new sibling, or other stressors, can lead to children wetting the bed after being dry for a long period.
Wet dreams begin during puberty when the body starts making more testosterone, a male hormone. Some guys may feel embarrassed or even guilty about having wet dreams. But they're are a normal part of growing up and you can't stop them from happening.

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.
While semen may contain ingredients that can benefit skin, the small quantity of these ingredients is unlikely to provide any benefit. Putting semen on the skin or consuming it also carries the risk of developing an allergic reaction and sexually transmitted infections (STIs).
Sometimes the link between the bladder and the brain isn't fully developed yet, he said, and more boys than girls tend to be bedwetters because girls mature faster. But by age 15, 99 percent of kids outgrow it, Barone, who did not work on the Journal of Pediatrics study, told Reuters Health.
At this age, your child may still be developing nighttime bladder control. If bed-wetting continues, treat the problem with patience and understanding. Lifestyle changes, bladder training, moisture alarms and sometimes medication may help reduce bed-wetting.
Bedwetting causes
Some children have small bladders or don't produce enough of a hormone (vasopressin) that reduces urine production during sleep. Bedwetting can be triggered by stress and by changes in the family, even positive ones, like a new baby or a different bedtime schedule over vacation.
Most guys have wet dreams at some point during puberty and even sometimes as adults. However, they usually happen less or stop altogether as guys get older and reach the end of puberty. Some guys may feel embarrassed or guilty about having wet dreams, but they're a normal part of growing up.
How to Explain Wet Dreams Simply. "Sometimes when the body is practicing making semen it could leak out at night. This is often called a wet dream or what your health teacher or doctor may call a nocturnal emission. Some boys have wet dreams, some do not.
