In the proliferative phase, the follicles start developing, hence, called the follicular phase.
Secretory phase is also called as luteal phase mainly controlled by progesterone secreted by corpus luteum. Estrogen further thickens the endometrium maintained by progesterone.
Menstruation occurs due to decline in progesterone level and involves the breakdown of the overgrown endometrial lining.
Capacitation occurs in
Rete testis
Epididymis
Vas deferens
Vas deferens
The difference between spermiogenesis and spermiation is
In spermiogenesis spermatids are formed, while in spermiation spermatozoa are formed.
In spermiogenesis spermatozoa are formed, while in spermiation spermatids are formed.
In spermiogenesis spermatozoa are formed, while in spermiation spermatozoa are released from sertoli cells into the cavity of seminiferous tubules.
In spermiogenesis spermatozoa from sertoli cells are released into the cavity of seminiferous tubules, while in spermiation spermatozoa are formed.
Hormones secreted by the placenta to maintain pregnancy are
hCG, hPL, progestogens, prolactin
hCG, hPL, estrogens, relaxin, oxytocin
hCG, progestogens, estrogens, glucocorticoids
hCG, hPL, progestogens, estrogens
The stage during which separation of the paired homologous chromosomes begins is
Pachytene
Diplotene
Zygotene
Diakinesis
