What triggers the development of the testis instead of ovaries in the developing fetus?

What cells produce the anti-mullerian hormone. Which sex produces this?

At what vertebral level do the tetes originate?
T10
What are the two phases of the uterus?
Proliferative phase
Secretory phase
What signifies on a histology slide whether the uterus is in a proliferative or secretory phase?
The glands in proliferative will be round and have the presence of mitotic figures
In secretory phase the glands become more irregular filled with secretions with NO mitotic bodies
What are the two main layers of the ovary?
The medulla
The cortex
What structures are contained within the medulla of the ovary
CT
Helicine arteries, veins, lymph (all these structures are close togther and at the periphery is termed the hilum
What structures are contained within the cortex of the ovary
It is where follicular development occurs
What are the two layers of the endometrium in the uterus that are related to menstration?
The stratum basalis
Stratum functionalis
Which layer of the endometrium in the uterus rebuilds the walls after menstruation?
