Question

Estrogen is a hormone secreted by the ovary. It is secreted in

greater amounts after menstruation and before ovulation. Among its
many effects, it causes up regulation of receptors in the uterus
for another hormone secreted by the ovary called progesterone.
Progesterone is secreted after ovulation. A major effect of
progesterone is to cause the uterus to become ready for the embryo
to attach to its wall following ovulation. Pregnancy cannot occur
unless the embryo attaches to the wall of the uterus. Predict the
consequences if the ovary secretes too little estrogen.

Answer 1

The absence of estrogen may lead to many symptoms:

1. Irregular periods
2. Anovulation, and therefore, infertility
3. Hot flashes
4. Decreased vaginal lubrication, which can lead to painful intercourse
5. Depression, because estrogen stimulates serotonin release
6. Osteoporosis and bone fractures
7. Weight gain

Usually the treatment for low estrogen levels is hormone replacement therapy (orally, vaginally or topically)
