Question

The difference between spermiogenesis and spermiation is :
A. In spermiogenesis, spermatozoa from sertoli cells are released in the cavity of seminiferous tubules , while in spermiation spermatozoa are formed.
B. In spermiogenesis, spermatids are formed, while in spermiation spermatozoa are formed.
C. In spermiogenesis, spermatozoa are formed , while in spermiation spermatozoa are released from sertoli cells into the cavity of seminiferous tubules.
D. In spermiogenesis, spermatozoa are formed , while in spermiation spermatids are formed.

Answer 1

Hint: Spermiogenesis means the transformation of spermatids into spermatozoa or sperms. In spermiation the release of sperms from seminiferous tubules through Sertoli cells occurs.

Complete Answer:
Spermiogenesis is the process of transformation of spermatids into spermatozoa. In the final stage of spermatogenesis, there is maturation of spermatids into mature and movable / motile spermatozoa. In spermiation mature spermatids are released from Sertoli cells into the lumen of the seminiferous tubule, before their passage to the epididymis.

Sl.No	Spermiogenesis	Spermiation
1.	It is the process of transformation of spermatids into spermatozoa	It is the process of release of spermatozoa from sertoli cells
2.	Spermatids are formed	Spermatozoa is formed
3.	It occurs in seminiferous tubules	It occurs in sertoli cells

, the correct option is C) In spermatogenesis, spermatozoa are formed , while in spermiation spermatozoa are released from sertoli cells into the cavity of seminiferous tubules.

Note: Defects in spermiogenesis and spermiation are seen as poor sperm motility, reduced or low sperm count, and abnormalities in the sperm morphology. This can lead to problems in egg fertilization, therefore, it can lead to problems in conceiving naturally.
