The value of LH supplementation in young women with diminished ovarian reserve treated with GnRH Antagonist Protocol for ovarian hyperstimulation in ICSI-cycles

Objectives:To compare the success of two controlled ovarian hyperstimulation protocols; rFSH + hp-hMG with only rFSH in the GnRH antagonist protocol in diminished ovarian reserve under 35 years of age. Material and methods: Data from January 2015 to June 2019 were abstracted from the hospital records of IVF Clinic. The women younger than 35 years of age who were diagnosed as diminished ovarian reserve and underwent standard GnRH antagonist protocol were included. Patients in Group-1 underwent controlled ovarian stimulation with rFSH alone and Group-2 with rFSH in combination with hp-hMG. Patients in both groups were divided into three subgroups according to their antral follicle count at Day 3: < 4 (a), 4-6 (b), and 7-10 (c). Demographic features and IVF outcomes of the patients were extracted. Results:Total number of retrieved oocytes, was higher in Group-1 than Group-2 (6.5 +/- 2.1 vs 5.5 +/- 2.3, respectively, p < 0.001). However, there were no significant differences between the two groups in terms of clinical pregnancy rate, implantation rate, miscarriage rate and live birth rate. Although the main study outcome parameters did not show significant difference between Group-1a and Group-2a, the number of mature oocytes (5 +/- 2.8 vs 1.8 +/- 1.2, respectively, p = 0.006) was higher in Group-1a. Conclusions:We observed no beneficial effect of LH supplementation during IVF for the treatment of women under 35 years old with diminished ovarian reserve in the first treatment cycle when compared with rFSH only in the antagonist protocols.

Automated summary

The study compared the success rates of two controlled ovarian hyperstimulation protocols in women under 35 with diminished ovarian reserve. The results showed that there were no significant differences in clinical pregnancy rate, implantation rate, miscarriage rate, and live birth rate between the two groups.
