1. Number of products
2. Gonadal hormones

Answer 1

Sr. No.	Basis	Oogenesis	Spermatogenesis
1.	Number of products	In oogenesis, one functional ovum and two to three non-functional polar bodies are produced from one primary oocyte.	In spermatogenesis, four functional spermatozoa are produced from one primary spermatocyte.
2.	Gonadal hormones	Oogenesis is regulated by the hormones estrogen and progesterone, which are secreted by the ovarian follicles and corpus luteum.	Spermatogenesis is regulated by androgens, primarily testosterone, which is secreted by the Leydig cells.
