Every day about 100 million sperm are produced in each human testicle, and about 200 million sperm released per ejaculation. Unused sperm cells may be resorbed or expelled out of the body in urine. As per literature (Reijo et al. 1995) during his lifetime, a human male can produce 10xE12 to 10xE13 sperm
Ten spermatozoa will be produced from ten spermatids. Egg cells are not formed from spermatids.
One spermatogonia will produce four spermatids through the process of spermatogenesis.
Four spermatids are formed from one spermatocyte during spermatogenesis. This process involves meiosis, which results in the halving of the chromosome number from diploid to haploid.
Each primary spermatocyte undergoes meiosis to produce four haploid spermatids.
In male animals, the primary sex cells (sperm) are produced in the testes through a process called spermatogenesis. During spermatogenesis, each primary spermatocyte undergoes two rounds of division to produce a total of four daughter cells, called spermatids. These spermatids then mature into functional sperm cells.
23 chromosomes are present in spermatids
The primary functions are a. Spermatogensis: to produce sperm, male gametes and reproductive cells. b. Secretion of hormone chiefly testosterone.
epididymis
Spermatids are stored in the seminiferous tubules of the testes in humans. They are formed from the process of spermatogenesis and eventually mature into spermatozoa (sperm cells).
At the end of Meiosis II, Spermatids are formed
Four megaspores are formed from meiotic division of megapore mother cell which is diploid. We know that diploid cells undergo meiosis to give haploid cells. So, it seems to me that megaspores are haploid.
