Ovaries make both estrogen and progesterone. Progesterone is released with the eggs and for a while after to help the body prepare for the possibility of pregnancy. If pregnancy doesn't occur, then the lesion on the ovary where the egg cell was released dries up and shrinks, reducing progesterone, and estrogen rises again. If pregnancy does occur, the corpus luteum (literally "yellow body") continues to secrete progesterone for the rest of the month until the growing placenta can take over that job. The placenta also produces a great deal of estriol (a weaker form of estrogen which helps prepare the breasts without harming the fetus or causing any reproductive symptoms).
The prefix "pro-" means "for," "gest" is the same root as in the word gestation, and, "sterone" is a common ending for steroid hormones. So literally, the word progesterone means "a hormone for helping pregnancy."
progesterone is released after the egg is released from the ovary.

The target organ for progesterone is the ovary and the embryo
Two hormones secreted by the ovary are estrogen and progesterone. Estrogen is responsible for the development of female reproductive organs and secondary sexual characteristics, while progesterone helps regulate the menstrual cycle and prepare the uterus for pregnancy.
Corpus luteum from ovary produce the hormone, progesterone. After the implantation of the pregnancy the endometrium terns into decidua. Then onwards the placenta produces the hormone, progesterone to term.
Ovary produce two hormones. First is estrogen and second is progesterone.
In unfertilized ovum mainly progesterone (high quality) and low quantity of estrogen is released from the corpus leuteum (remaining part of the roptured follicle in ovary. This increased progesterone prepares the uterus for pregnancy. If fertilization occur progesterone estrogen and hCG are released.
