Relationship between the positions of cytoplasmic granulation and the oocytes developmental potential in human.

To evaluate the relationship between the positions of cytoplasmic granulation and the oocytes developmental potential in human, we detected the developmental potentials of oocytes with centrally located cytoplasmic granulation (CLCG). The patients' age, body mass index (BMI), Infertility duration, follicle stimulation hormone (FSH) levels, average stimulate ovulation days, gonadotropin (GN) total dose, fertilization rate, cleavage rate, high quality embryo rate, embryo utilization rate and pregnancy rate were analyzed. The results showed that there were no significant difference on patients' age, BMI, infertility duration, FSH levels, average stimulate ovulation days, GN total dose, pregnancy rate and birth rate between CLCG group and control group in patients with BMI < 24 (P > 0.
