what inhibits the ovary from secreting progesterone
It will only occur on one side of the body, in the ovary in which it developed. Corpus luteum cysts, which occur after ovulation. These cysts are stimulated by LH, which is attempting to make the follicle, now a cyst, ovulate. The corpus luteum produces progesterone to support the growth of an embryo. If conception doesn't take place this normally breaks down and is reabsorbed.
