Abstract
To analyze whether combinations of polymorphisms within FSHR gene influence ovarian response (OR) to stimulation. A multicenter prospective cohort study was conducted from 11/2016–06/2019 in Europe and Asia including predicted normo-responders under 38y. Patients underwent ovarian stimulation using fixed-dose 150 IU rFSH in a GnRH antagonist protocol. FSHR variants rs6165, rs6166 and rs1394205 were genotyped and combined in diplotypes. OR was compared following multivariable regression. rs6165/rs6166 genotype AG/AG exhibited more hypo-response (33.1% vs. 24%,adjOR 1.77 [95%CI 1.08–2.90]) and lower Follicle to Oocyte Index (FOI) compared with other diplotypes (EMD -11.72 [95%CI -20.89;-2.55]). Genotype GG/AA showed less hypo-response (19.1% vs. 31%, adjOR 0.48 [95%CI 0.24–0.96]), while AA/AA had higher FOI (EMD 20.04 [95%CI 4.51;35.56]). Concerning rs6165/rs1394205, less oocytes (EMD -1.99 [95%CI -3.57;-0.42]) and lower FOI (EMD -12.07 [95%CI -23.09;-1.05]) were retrieved with genotype AG/AG and higher FORT with genotype AA/AG (EMD 17.88 [95%CI 3.77;31.98]). Regarding rs6166/rs1394205, less hypo-response (16.3% vs. 29.5%,adjOR 0.42 [95%CI 0.19–0.97]), more oocytes (EMD 3.45 [95%CI 1.57;5.34]) and higher FOI (EMD 17.57 [95%CI 4.41;30.73) were found with genotype AA/GG. Genotype AA/AG presented higher FORT (EMD 13.47 [95%CI 2.51,24.42]), while more hypo-response (56.3% vs. 26.4%,adjOR 6.30 [95%CI 1.88;21.08]) and lower FOI (EMD -23.51 [95%CI -45.04;-1.97]) was reported with AG/AA. In accordance with our previous studies, FSHR polymorphisms have a statistically significant impact on OR, both individually and in association. However, only rs6166/rs1394205 genotype AA/GG seems to have a clinically significant effect, with a decrease in the prevalence of hypo-response, higher oocyte yield and increase in FOI.
