The difference between spermiogenesis and spermiation is

  By GK Planet Team       Monday, 25 June 2018
Q. The difference between spermiogenesis and spermiation is
  1. In spermiogenesis spermatozoa are formed, while in spermiation spermatozoa are released from sertoli cells into the cavity of seminiferous tubules.
  2. In spermiogenesis spermatids are formed, while in spermiation spermatozoa are formed.
  3. In spermiogenesis spermatozoa from sertoli cells are released into the cavity of seminiferous tubules, while in spermiation spermatozoa are formed.
  4. In spermiogenesis spermatozoa are formed while in spermiation formed. spermatids are
Answer: In spermiogenesis spermatozoa are formed, while in spermiation spermatozoa are released from sertoli cells into the cavity of seminiferous tubules.

Spermiogenesis is the final stage of spermatogenesis, which sees the maturation of spermatids into mature, motile spermatozoa. The spermatid is a more or less circular cell containing a nucleus, Golgi apparatus, centriole and mitochondria. All these components take part in forming the spermatozoan.
The process of spermiogenesis is traditionally divided into four stages: the Golgi phase, the cap phase, formation of tail, and the maturation stage.
The process of spermatogenesis. 1. Primary spermatocyte 2. Secondary spermatocytes 3. Spermatids 4. Sperm

For humans, the entire process of spermatogenesis is variously estimated as taking 74 days (according to tritium-labelled biopsies) and approximately 120 days (according to DNA clock measurements). Including the transport on ductal system, it takes 3 months.
Spermiation: The process of sperm release.
Spermiation is the process by which mature spermatids are released from Sertoli cells into the seminiferous tubule lumen prior to their passage to the epididymis.
The mature spermatozoa are released from the protective Sertoli cells into the lumen of the seminiferous tubule and a process called spermiation then takes place, which removes the remaining unnecessary cytoplasm and organelles.
The spermatid is the haploid male gametid that results from division of secondary spermatocytes. As a result of meiosis, each spermatid contains only half of the genetic material present in the original primary spermatocyte.
