Explanation:

Key Differences Between Spermatogenesis and Oogenesis

Spermatogenesis is the production of sperms from spermatogonia in the seminiferous tubules of the testis in a male. Oogenesis is the production of the ovum from oogonia inside the ovary of a female.

Answer 2

By a process, called gametogenesis, the testicule in a man and the ovary in a woman produce gametes, that is to say, spermatozoa and eggs. The gametogenesis responsible for the production of sperm is called spermatogenesis and that responsible for the production of the egg is called oogenesis.

Spermatogenesis:

• The production of spermatozoa from spermatogonia is called spermatogenesis.
• Occurs in the testes
• All the steps are completed in the testicles.
• It's an ongoing process.
• Produces mobile gametes
• Equal cytokinesis occurs during spermatogenesis, producing four spermatozoa.

Oogenèse/Oogenesis:

• La production d'œufs d'oogonie est appelée oogenèse.
• Occurs inside the ovary
• Most of the oogenesis occurs inside the ovary. The last stages occur in the oviduct.
• It's a discontinuous process. The early stages take place in the fetus and others in the later stages of life.
• Produces non-motile gametes
• Unequal cytokinesis occurs during oogenesis, eventually producing one egg and four polar bodies
