Cells in this part of a follicle produce androgens

LH

This hormone signals the theca to produce androgens

1

This is the day in the cycle on which menses begins

FSH

This hormone is necessary for the development of the follicular antrum

Granulosa

This part of a follicle is responsible for estradiol production

androstenedione

This is the predominant androgen produced in the theca and exported to the granulosa

FSH

This hormone starts a signaling cascade in the granulosa cell that allows conversion of androstenedione to estrone

estrone

Androstenedione is converted to this estrogen in the granulosa cell

prostaglandins

These hormones cause vasospasm during menses, decreasing bleeding

estrogen

This hormone is critical for endometrial growth

estrogen

In the early/mid follicular phase, this hormone negatively feeds back upon GnRH, FSH and LH

positive

In the late follicular phase, is estrogen feedback positive or negative upon GnRH

inhibin

This granulosa product negatively feeds back on FSH in the late follicular phase

progesterone

This hormone positively feeds back on LH and GnRH during the late follicular phase

corpus luteum

After ovulation, this is the source of estrogen, progesterone and inhibin

negative

In the luteal phase, is estrogen feedback positive or negative upon GnRH

androgens

Pubic/axillary hair growth and libido are caused by these in women
