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).
Sperm production in the testes takes place in coiled structures called seminiferous tubules. Along the top of each testicle is the epididymis. This is a cordlike structure where the sperm mature and are stored. The release process starts when the penis fills with blood and becomes erect.
Once they're mature, sperm live in “storage” in the testicles—specifically, in the cauda epididymis—for as long as a few weeks. After that, they're reabsorbed into the body. But while in storage, sperm quality is decreasing fairly rapidly.
One testicle is usually sufficient to produce semen and testosterone.
Every day, a healthy adult male can produce around 70 to 150 million sperm. They are only 55 millionths of a millimetre (or 55 microns) in length. Mature sperm is stored in the epididymis – the coil-like structure that runs across the top of each testicle.
Vas deferens.
This is a tube in which the sperm is stored and it carries the sperm out of the scrotal sac. The vas deferens is between the epididymis and the urethra and connects these together.
While there is no definite age at which male ejaculation ceases, it has been suggested that it may happen when a man reaches his late 40s or early 50s. It is important to note, however, that this is not a universal rule and some men may continue to ejaculate at a later age.
The membrane (lining) of the epididymis absorbs most of the sperm where it dissolves. The rest of the unused sperm is absorbed simply and naturally by your body. Sperm is produced even if a man is not sexually active or has difficulty in achieving orgasm.
A male's body is constantly creating sperm, but sperm regeneration is not immediate. On average, it takes a male around 74 days to produce new sperm from start to finish. Although the average time is 74 days , the actual time frame for an individual to make sperm can vary.
Usually, each millilitre of semen contains millions of spermatozoa (sperm), but the majority of the volume consists of secretions of the glands in the male reproductive organs. It is quite normal for semen to form jelly-like globules and this does not indicate any health or fertility problem.
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.
Yellow semen is rarely cause for concern. It may be due to aging, abstinence or the presence of urine. Infections, including prostatitis, sexually transmitted diseases (STDs) and urinary tract infections (UTIs), can turn semen yellow.
Complications of delayed ejaculation can include: Diminished sexual pleasure for you and your partner. Stress or anxiety about sexual performance. Marital or relationship problems due to an unsatisfactory sex life.
When sperm are inside women's body, they can live for up to 5 days. If you're a man and you have sex even a few days before your partner ovulates, there's chance they may get pregnant.
How many drops of sperm are needed to get pregnant? Studies say that while ejaculating, a man may produce semen ranging between 2ml to 5ml. 1 ml of semen contains about 20 million sperms. However, it takes only one sperm to fertilize an egg and get pregnant.
Ejaculating is a natural bodily function that can bring pleasure and release tension. Ejaculating daily is unlikely to cause any harm to men who are in good overall health, but excessive ejaculation can lead to temporary fatigue or discomfort in the genital area and may affect sperm count over time.

Once your body makes testosterone, it can release sperm. This means you'll be able to fertilize an egg if you decide to have a baby in the future. It also means you can get a girl pregnant if you have sex.
Unejaculated sperm is not harmful to the body and does not build up. The body reabsorbs sperm that does not leave through ejaculation. This has no side effects on sex drive or fertility. However, there may be possible side effects in people who delay or avoid ejaculating when sexually aroused.
Testicular volume rapidly increases during puberty and peaks at age 30 years. Subsequently, the volume of the testes stabilizes in a plateau-like manner until age 60 years. After age 60 years, this study shows that testicular volume decreases significantly.
masturbating 1 to 2 hours before having sex. using a thick condom to help decrease sensation. taking a deep breath to briefly shut down the ejaculatory reflex (an automatic reflex of the body, during which you ejaculate) having sex with your partner on top (to allow them to pull away when you're close to ejaculating)
According to some studies, 18-year-old males have a refractory period of about 15 minutes, while those in their 70s take about 20 hours, with the average for all men being approximately half an hour.
Very strong smell: Bacteria and other germs can change the way semen smells. If semen has a foul and overpowering odor or gets worse with time, it may be a sign of an infection or sexually transmitted disease. Sweet smell: Normal semen can smell slightly sweet because of the fructose it contains.
