A spermatozoon (/ s p ər ˌ m æ t ə ˈ z oʊ. ən, ˌ s p ɜːr m ə t ə-/; [1] also spelled spermatozoön; pl.: spermatozoa; from Ancient Greek σπέρμα (spérma) 'seed' and ζῷον (zôion) 'animal') is a motile sperm cell produced by male animals relying on internal fertilization.

2024年2月27日 · The term spermatozoa (singular: spermatozoon), also known as sperm, refers to the male sex cells or gametes. They are formed through the process of spermatogenesis, which begins at puberty with the proliferation progenitor (stem) cells called spermatogonia.

spermatozoa Microscopic cells about 0.05 mm long occurring in millions in seminal fluid. Spermatozoa are male GAMETES, carrying all the genetic contribution from the father and bearing either an X chromosome to produce a daughter, or a Y chromosome to produce a son.

3 天之前 · This page introduces spermatogenesis the development of spermatozoa, the male haploid gamete cell. In humans at puberty, spermatozoa are produced by spermatogonia meiosis in the seminiferous tubules of the testis (male gonad).

2024年11月6日 · Sperm cells, scientifically referred to as spermatozoa, serve as the male gametes in sexual reproduction. These specialized cells originate from the male reproductive organs and play a crucial role in fertilization, as they unite with female egg cells to create a diploid zygote, initiating the development of a new organism.

2025年1月18日 · sperm, male reproductive cell, produced by most animals. With the exception of nematode worms, decapods (e.g., crayfish), diplopods (e.g., millipedes), and mites, sperm are flagellated; that is, they have a whiplike tail. In higher vertebrates, especially mammals, sperm are produced in the testes.

2024年8月27日 · A spermatozoon, in plural spermatozoa, or sperm cell is the male reproductive cell that is produced in the man´s testicles in a process called spermatogenesis. The sperm cell´s function is to enable sexual reproduction through its union with the female egg during fertilization.

The egg is among the largest cells in an organism, while the sperm (spermatozoon, plural spermatozoa) is often the smallest. The egg and the sperm are optimized in opposite ways for the propagation of the genes they carry.
