Sperms are produced inside the testes of male reproductive system. testes are the primary reproductive organ of human males. they are located in the scrotum outside the body. they produces sperms, which engage into a coiled tube called epididymis and get stored there. sperms are then carried away through the vas deferens , which joins the urethra . on way to the urethra , sperms also receives secretions from the seminal vesicles and the prostrate gland. the urethra carries sperms to the penis, which opens outside the body.
The process in which the sperms are produced is called spermatogenesis. sperms are usually produced structures like coiled which are present in testes called seminiferous tubules .
The seminal vesicles and the prostrate gland produces seminal fluid, which then gets mixed with sperms to form semen.
In humans, fertilisation is internal, sperms are introduced in the vagina by the penis during copulation. the sperms moved up through the cervix , enters the uterus and pass into the oviducts. in the oviducts , the eggs gets fertilised by one of the sperms. Zygote is formed by the fusion of a sperm and an egg. this zygote divides multiple times to form a hallow ball of the cells called embryo.

How sperm is formed:
Spermatogenesis or transformation in spermatozoa
It comprises a series of processes all aimed at improving the ability of the sperm to penetrate the egg. These phenomena will be the formation of the acrosome or cap with high glycoprotein content and proteolytic enzymes, development of the tail or flagellum that allows the movement of the spermatozoon, transformation of the nucleus in peripheral position and elimination of almost the entire cytoplasm. Once formed in the seminiferous tubes, they pass to the epididymis by the action of the contractile elements of the former.
As a result of this process, spermatozoa are produced, with 23 chromosomes, half the cell from which it originates (spermatogonia). The spermatozoon is a very specialized cell. The size of the cell is reduced, eliminating much of the cytoplasm and developing a long tail called the flagellum, which will allow it to move until reaching the ovum. It also has a large number of mitochondria that will give you the energy to move.
In man, spermatogenesis lasts about 100 days, which is important for assessing the effect of any treatment or toxic substance on sperm quality.
The spermatozoon leaves the testicles and mixes with the fluids produced by the seminal vesicles and the prostate to form semen. These liquids are essential for feeding and survival of the spermatozoa until reaching the ovum. Only 10% of semen is made up of sperm, which can be counted in the hundreds of thousands.
As with the formation of ova, the process is regulated and controlled by the endocrine system and, in turn, the testes function as endocrine glands.
