Activin is a glycoprotein that is produced within granulosa cells in females and sertoli cells in the male. The target tissue for activiin in the male is the epididymis whilst in the female it is the anterior pituitary gland, specifically gonadotroph cells. In males and females activin stimulates FSH secretion.

Prostaglanin is a C<sub>2</sub>O fatty acid and is produced within the uterine endometrium and vesicular glands. The target tissue in the female is the corpus luteum, uterine myometrium and ovulatory folicles. In the male foetus prostaglandin affects the the metabolic activity of spermatozoa and epididymal contractions. In the female prostaglandin results in luteolysis, the induction of tone and contractions within the uterus and ovulation.

In the female prostaglandin can cause luteolysis and also cause the induction of tone and contractions within the uterus and ovulation.

During the second half of the [[Oestrous_Cycle_-_Anatomy_%26_Physiology#Luteal_Phase|luteal phase]] of the reproductive cycle prostaglandins are synthesised. These prostaglandins are lipid soluable and are therefore able to diffuse through cells walls into the ovarian artery. The overall concentrations of prostaglandins within the blood are reasonably low as the hormone is broken down within the lungs.

PGE<sub>2</sub> is another form of prostaglandin that is produced by the ovary, uterus and embryonic membranes. It's target tissue in females is the corpus luteum and the oviduct where it helps induce ovulation and the secretion of progesterone from the corpus luteum.
