Sperms are very essential for fretility in every man. Sperm cells are very small but the egg’s are largest in shape, it is estimated that it will take 175,000 sperm to weigh as much as a female egg, which is a lot of sperm; these Sperms are made up of sugar, protein, Vitamin C, zinc and prostaglandin’s. The number of sperms are totally depend in a unit volume of semen. So, A normal sperm count is between 20 million and 150 million sperm per millilitre. A sperm count below 20 million sperm per millilitre is low and may indicate a fertility problem. if a man’s sperm count is less than the normal range, it is still possible to father a child. The sperm count depends on how long ago the man last ejeculated.
It is thought that a student of Antonij van Leeuwenhoek first discovered sperm in 1677 in the city of Delft. One day he brought to the acknowledged master of microscopy, Leeuwenhoek, a bottle containing semen and pointed out that small animals could be seen moving about in the ejaculate. And after this research, scientist knew the fact of sperm that how sperm’s are necessary in ever men?
So; Sperm, and “seminal plasma” are the two components of semen and Seminal plasma, in turn, is produced by contributions from the seminal vesicle, prostate, and bulbourethral glands. Seminal plasma of humans contains a complex range of organic and inorganic constituents.
The seminal plasma provides a nutritive and protective medium for the spermatozoa during their journey through the female reproductive tract. The normal environment of the vagina is a hostile one for sperm cells, as it is very acidic (from the native microflora producing lactic acid), viscous, and patrolled by immune cells. The components in the seminal plasma attempt to compensate for this hostile environment. Basic amines such as putrescine, spermine, spermidine and cadaverine are responsible for the smell and flavor of semen. These alkaline bases counteract the acidic environment of the vaginal canal (which is harmful to sperm), and protect DNA inside the sperm from acidic denaturation; According Wikipedia.
In other term: during an erection, sexual arousal causes increased blood flow through the arteries in the penis. These arteries expand, allowing for more blood to enter the penile region, while the veins that control the blood flowing out of the penis simultaneously contract. The hardening effect that this process has on the tissues of the penis is what causes an erection. At the peak of penile arousal, ejaculation occurs, in which the sperm is released from the penis. The larger the amount of fluid ejaculated, the more pleasurable the sexual experience, as well as the greater chance for increased sperm count.
Its very long procedure to maturing a single sperm, it takes 64 days to growing one sperm, after they move into the epidiymis- its a20 foot long series of thin-coiled tubes, so another 12 days they mingle with each other and now they are ready to beat the others in the race for the egg. After approximately 90 seconds the sperm reaches the cervix. Its very small journey which can take from anything from 5 minutes to 1 hour continues up through the womb, (and) into the fallopian tubes and on towards the egg, which all sounds a little tiring.

Pregnancy is totally depend to the good timing of intercourse so If the woman knows the timing of intercourse and also her cycle than its good for both; man as well as woman. Unlike men who are generally fertile 365 days of the year there is only a small window of fertility each cycle for a woman.
Quantity and quality both are the parameter of the sperm to determinants of fertility. According the WHO, if man has suffering infertility problem than his semen would be below 20-million/ ml.
There are some facts so the research shows that: –
1– 25% of couples will conceive in the first month of trying.
2– 60% will take six months.
3– 80% will have conceived within 12 months of trying for a pregnancy.
4– Doctors classify the 20% that have not conceived within 12 months as infertile.
Frustrating experience, premature ejaculation, or weak ejaculation with ineffective orgasms, extreme heat and cold temperatures. All experiences can prohibit sperm count and decrease sperm activity.
Full and healthy diet is essential for a body so you can make more and more as we say millon sperm in a minute. A balanced diet is one that contains carbohydrate, protein, fat, vitamins, mineral salts and fibre in the correct proportions. Although there is a lot of argument about what are the correct guidelines, try to have 55%- 60% carbohydrates, 25%-30% fat and 15%-20% protein per day. Sperm can live up to approximately 5 days in fertile cervical fluid. So even if you haven’t had penetrative intercourse you can still get her pregnant.
