The release of sperms from the seminiferous tubules is called spermiation.

What is Spermiation?
Spermiation is the process by which mature sperm cells are released from the seminiferous tubules in the testes. It is the final step in the complex process of spermatogenesis, which involves the production and maturation of sperm cells.

Process of Spermatogenesis:
Spermatogenesis is a continuous process that occurs in the seminiferous tubules of the testes. It involves the production of sperm cells from spermatogonial stem cells through a series of cell divisions and differentiation.

Stages of Spermatogenesis:
1. Spermatogonium: Spermatogonial stem cells divide by mitosis to produce spermatogonia, which are the precursor cells for sperm production.
2. Primary Spermatocyte: Spermatogonia undergo further divisions and differentiate into primary spermatocytes.
3. Secondary Spermatocyte: Primary spermatocytes undergo the first meiotic division, resulting in the formation of two secondary spermatocytes.
4. Spermatids: Secondary spermatocytes undergo the second meiotic division, resulting in the formation of four spermatids.
5. Spermatozoa: Spermatids undergo a process called spermiogenesis, where they undergo extensive morphological changes to develop into mature sperm cells.
6. Spermiation: The mature sperm cells are released from the seminiferous tubules into the lumen, where they are then transported to the epididymis for further maturation and storage.

Key Differences:
1. Spermiation: It is the release of mature sperm cells from the seminiferous tubules.
2. Spermatogenesis: It is the overall process of sperm cell production, which includes the development and maturation of sperm cells from spermatogonia to spermatozoa.
3. Spermiogenesis: It is the process of maturation and morphological changes of spermatids to form spermatozoa.
4. Spermiosis: This term is not commonly used in the context of sperm cell release and is not the correct term for the process.

In conclusion, spermiation refers to the release of mature sperm cells from the seminiferous tubules, marking the completion of spermatogenesis. It is a crucial step in the production of functional sperm cells for fertilization.
