what are the diploid cells that are perpetually mitotic in the seminiferous tubules, such that men can continue to produce new sperm their entire life?
spermatozoa
spermatids
spermatogonia
spermatocytes

Explanation:

1. After ovulation, the ovarian follicle transforms into the Corpus Luteum. The Corpus Luteum secretes progesterone to prepare the uterus for potential pregnancy. Chorionic gonadotrophin is mainly associated with pregnancy (produced by the developing embryo), and the follicle is not shed and lost immediately after ovulation. Also, follicles are present in the female reproductive system.
2. Spermatogonia are diploid cells in the seminiferous tubules. They undergo mitosis to produce more spermatogonia (to maintain the population) and cells that will eventually develop into sperm. Spermatozoa are mature sperm (haploid), spermatids are haploid cells formed from meiosis (closer to spermatozoa in development), and spermatocytes are involved in meiosis (diploid at the start of meiosis but become haploid through the process).

Answer:

1. It transforms into the Corpus Luteum
2. Spermatogonia
