No significant disparities were observed between the implantation group (n = 82) and the non-implantation group (n = 83) with respect to the following clinical characteristics: age, Body Mass Index (BMI), infertility duration, types of infertility, fertilization method, basal serum Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), Estradiol (E2) levels, antral follicles, endometrial thickness, duration of gonadotropin use, total dosage of gonadotropins and the number of transferred embryos. This evidence concerns the gene PLOD1 and Infertility.
