A self-controlled study was conducted to retrospectively investigate the clinical outcomes of 104 aged infertile patients who didn＇t get pregnant in the first IVF/ICSI-ET treatment by stimulating with GnRH-a long protocol （non-PPOS group）, and underwent PPOS protocol （PPOS group） in the second cycle between January 2016 and December 2016 in the Center for Reproductive Medicine, Renmin Hospital of Wuhan University. The primary outcomes included clinical pregnancy rate of frozen-thawed embryos transfer （FET） in PPOS group, and good-quality embryo rate in both groups. The secondary outcomes were fertilization rate, egg utilization rate and cycle cancellation rate. The results showed that there were no significant differences in basal follicle stimulating hormone （bFSH）, antral follicle count （AFC）, duration and total dosage of gonadotropin （Gn）, number of oocytes retrieved, intracytoplasmic sperm injection （ICSI） rate, fertilization rate, and cycle cancellation rate between the two groups （P〉0.05）. However, the oocyte utilization rate and good-quality embryo rate in PPOS group were significantly higher than those in non-PPOS group （P〈0.05）. By the end of April 2017, 62 FET cycles were conducted in PPOS group. The clinical pregnancy rate and embryo implantation rate were 22.58% and 12.70%, respectively. In conclusion, PPOS protocol may provide better clinical outcomes by improving the oocyte utilization rate and good-quality embryo rate for aged infertile patients who failed to get pregnant in the first IVF/ ICSI-ET cycles.展开更多

This seems to bedue to a promoting and not initiating effect. A synergic effect of estradiol and hyperinsulinism has been shown. Insulinplays a role in the increase of breast cancer risk when associated with android obesity, sedentariness, type II diabetes,and high glycemic index food, alcohol and trans fatty acids intake. Natural menopause induces insulin resistance anddoes not induce a risk decrease. The role of insulin gives a new outlook on the influence of HRT in breast cancer promotion:estradiol alone, which improves insulin-sensitivity, does not increase breast cancer risk. Artificial progestinsassociated with estrogens increase the risk, whereas estrogens associated with progesterone do not. This could be dueto the fact that artificial progestins increase insulin resistance, whereas natural progesterone does not. Adipose tissue,which is an endocrine gland, is insulin dependant. Breast cancer and its seriousness are correlated to adipocytokincirculating levels such as resistin, leptin, interleukin 1, adipocyte fatty acid-binding protein, and are inversely correlatedto the level of adiponectin. Insulin could play a synergic role with sexual steroids by a direct effect and by increasingadipose tissue secretions.展开更多
