Abstract
Background: Because of the unexpected and often dramatic inhibition of luteinizing
hormone (LH) secretion related with the usage of gonadotropin-releasing hormone
(GnRH)-antagonist, there has been a probable need for exogenous LH supplementation.
There is a basic and clinical evidences that show late development of follicle
needs an LH but there is a threshold for LH requirements during folliculogenesis.
Objective: The purpose of this study was to evaluate the changes in serum LH and the
identification of patients who benefit from the addition of LH.
Materials and Methods: Seventy volunteers for antagonist protocol in IVF cycle
were enrolled in this prospective cross-sectional study. The study was carried out in
Reproductive Health Research Center, University of Medical Sciences between July
2016 and February 2016. Serum LH level was estimated 24 h before and after the first
(GnRH) antagonist injection. The primary outcome was the serum level of LH and its
change in the three groups and the secondary outcome was Egg and Embryo quality.
Results: LH changes above or below 50% had no effect on the number of follicle, the
number of oocyte, Germinal vesicle oocyte, metaphase 1 oocyte, metaphase 2 oocyte,
endometrial thickness, and chemical and clinical pregnancy.
Conclusion: We evaluated the changes of serum LH in the patients who were entered
in the antagonist protocol. Our study showed no significant difference in LH levels 24
h before and after the injection of the antagonist between the three groups, and LH
changes did not affect the outcome of pregnancy.
