Cetrotide is a gonadotropin releasing hormone that helps control hormonal responses in women's body affecting the development of eggs. Cetrotide isblocking the trigger effect of GnRH. This blocking action stops the premature LH surge in women undergoing controlled ovarian stimulation before they begin. In doing so, this allows eggs to reach the level of development needed forfertilization. 


Clomid (clomiphene) is a non-steroidal fertility medicine. It causes the pituitary gland to release hormones needed to stimulate ovulation (the release of an egg from the ovary).

Endometriosis is a common condition where tissue that behaves like the lining of the womb (the endometrium) is found outside the womb. These pieces of tissue can be found in many different areas of the body, but they are most commonly found on the ovaries, on the lining of the pelvis behind the uterus and covering the top of the vagina. The condition is estimated to affect around two million women in the UK. Most of them are diagnosed between the ages of 25 and 40.
