Low ovarian response
Some women undergoing ovarian stimulation have a low response. Although it may be due to several causes, maybe the medications being used for stimulation should be replaced or perhaps the woman is a poor-responder.
Preparing for ovarian stimulation
The moment a woman decides to undergo an assisted reproduction treatment, a hormonal treatment that will stimualte the production of eggs and prepare the endometrium, should be started.
The term "ovarian reserve" refers to the number of oocytes a woman has. Unlike men, women are born with a fixed egg reserve; from puberty onward, an egg will mature each month until the reserve is empty.
The luteinising hormone is a type of gonadotropin hormone. It is secreted by the pituitary gland thanks to GnRH action and it is one of the responsibles for regulating woman's reproductive cycle.
Advantages of GnRH analogues
The main advantage o Regular growth of follicles is the main advantage of using GnRH analogues as a medicine in assisted reproduction for ovarian induction.
A larger number of eggs does not increase the chances for pregnancy
In an IVF treatment, it is necessary to stimulate egg production so that the ovary produces a greater number of eggs. Getting pregnant is easier this way.
Number of eggs obtained
After assisted reproductive treatments which require controlled ovarian stimulation, an ovarian drilling is performed in order to remove the eggs, and then counting them in order to know the number of eggs obtained.
