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.
The sperm in the testes move to the epididymis which is a long, coiled tube behind the testes. The primary function is to store and mature sperm so it can fertilize the egg. However, if the epididymis becomes injured, then there is a chance that the sperm will not mature and a man will not be able to reproduce with a woman.
In a more sustained pronunciation, gemination distinguishes the conditional (and possibly the future tense) from the imperfect: courrais 'would run' /kuʁ.ʁɛ/ vs. courais 'ran' /ku.ʁɛ/; or the indicative from the subjunctive: croyons 'we believe' /kʁwa.jɔ̃/ vs. croyions 'we believed' /kʁwaj.jɔ̃/.
The resulting spermatozoa are now mature but lack motility. The mature spermatozoa are released from the protective Sertoli cells into the lumen of the seminiferous tubule in a process called spermiation. The non-motile spermatozoa are transported to the epididymis in testicular fluid secreted by the Sertoli cells with the aid of peristaltic ...
The human sperm cell is haploid, so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell with 46 paired chromosomes. In mammals, sperm is stored in the epididymis and released through the penis in semen during ejaculation. The word sperm is derived from the Greek word σπέρμα, sperma, meaning "seed".
The Merriam-Webster Online Dictionary suggests the first pronunciation. Similarly, this pronunciation markup guide will choose the most widely used form. NOTE: This guide is designed to be simple and easy to use. This can only be achieved by giving up scope and freedom from occasional ambiguity.
Spermatozoa, in this case human, are a primary component in normal semen, and the agents of fertilization of female ova. Semen, also known as seminal fluid, is a bodily fluid that contains spermatozoa. Spermatozoa are secreted by the male gonads (sexual glands) and other sexual organs of male or hermaphroditic animals and can fertilize the ...
