The combined use of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) has improved IVF pregnancy rates in infertile women aged 35-40, but its mechanisms remain unclear. This prospective study will examine how FSH and LH combined treatment affects cumulus cell energy metabolism. Sixty participants will be divided into two groups receiving either combined therapy or FSH alone. The study will analyze patient characteristics, infertility history, and compare mitochondrial function in cumulus cells to evaluate treatment effectiveness.
