The number of sperm produced by different animals also varies enormously. Humans produce approximately 100 million sperm per ejaculate, while rams can produce 100 billion.
The largest sperm ever discovered belongs to a species of fruit fly, Drosophila bifurca, that has sperm over 2 inches in length - over 20 times their body size!
That means a fertile man may produce between 40 million and 1800 million sperm cells in total, though the majority produce between 40 and 60 million sperm cells per millilitre, giving an average total of 80 to 300 million sperm per ejaculation.
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.
Semen analysis results
Normal sperm densities range from 15 million to greater than 200 million sperm per milliliter of semen. You are considered to have a low sperm count if you have fewer than 15 million sperm per milliliter or less than 39 million sperm total per ejaculate.
The preliminary findings indicated that X spermatozoa are larger and stronger than Y spermatozoa, suggesting that they are more stable in an acidic pH than Y spermatozoa (Landrum and Shettles, 1960; Shettles, 1960).
Testes of mature stallions are normally capable of producing approximately 18 to 20 million sperm per gram of testicular tissue per day.
Sperm is the male reproductive cell. Smallest sperm is found in crocodiles and Amphioxus (. 02 mm).
Paleontologists say the fossilised animal sperm, found inside a tiny ostracod, could be 100 million years old. A team of paleontologists has discovered what they believe is the world's oldest animal sperm, frozen inside a tiny crustacean in a blob of tree resin in Myanmar 100 million years ago.

The male has a low sperm count. It could occur naturally or due to certain factors such as heat, particular drugs and toxic substances which kill many male sperm cells, according to Shettles.
New Delhi: Scientists at the Queen Mary University of London and the Chinese Academy of Science have discovered the world's oldest animal sperm inside a tiny type of crustacean trapped in amber around 100 million years ago in Myanmar.
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.
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.
Some studies suggest that moderate ejaculation (2–4 times per week) is associated with a lower prostate cancer risk. However, ejaculating more often doesn't mean your cancer risk drops even more.
Y sperm: are faster but survive for less time in the female genital tract. X sperm: are slower, but they are more resistant and therefore survive longer.
If the body is not properly hydrated, there may be less water in the semen, causing it to be thick or chunky. Anyone who wonders whether the thickness of their semen results from a health issue should drink plenty of water and see whether this resolves the issue.
Sperm production or function can be affected by overexposure to certain environmental elements, including: Industrial chemicals. Extended exposure to benzenes, toluene, xylene, herbicides, pesticides, organic solvents, painting materials and lead might contribute to low sperm counts.
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.
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.
No evidence suggests blocking sperm can cause harm or negative side effects. 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.
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)
Non-Ejaculating for 30 days helps with physical health
Even though there is no conclusive research to back the claim, many studies so far suggest that the high level of testosterone due to semen retention is directly linked with energy retention and mood upliftment.

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.
