Hi SarahLou,
Welcome to the community. There are some clinics that use growth hormones in most of their treatment cycles (unless there is a medical reason not to) and they tend to have quite good success rates. The research on the use of growth hormones is limited though. This study seems to show a positive outcome – bmjopen.bmj.com/content/7/10/e018107
One of the clinics i used to work at did use GH routinely and patients seemed to do well on it with no adverse reactions.
Hope that helps.
