The growth hormone (biotropin) and its breakdown products effect the oocyte differentiation process during their maturation process.
There are some women who suffer from low quality oocytes, which causes low quality embryos (egg factor).
There are many studies performed worldwide that provide evidence that combining growth hormone (which is given as a daily injection) throughout the hormonal treatments, greatly improve the quality of the oocytes.
Here in our clinic we have acquired a great deal of experience using this method, and have on many occasions received excellent results.
