What to Focus On
- Testis and ovary are primary sex organs.
- Each testis has about 250 lobules and 1 to 3 seminiferous tubules per lobule.
- Seminiferous tubules contain spermatogonia and Sertoli cells.
- Spermatogenesis starts at puberty.
- GnRH stimulates LH and FSH release.
- LH acts on Leydig cells.
- Ovary, oviducts, uterus, vagina, and external genitalia form the female reproductive system.
- Each ovary is 2 to 4 cm long.
- Each fallopian tube is 10 to 12 cm long.
Common Mistakes to Avoid
The sex of the baby is determined by the mother because the ovum decides the result of fertilisation.
Spermatogenesis and spermiogenesis mean the same thing.
Secondary spermatocytes are diploid because they are still part of sperm formation.
