Research Narrative:

1．Noninvasive clinical assay for differential diagnosis of azoospermia：

One of the important issues in male reproductive medicine is to determine, using the least invasive technology, men with azoospermia have mature spermatozoa in their testes or not. Azoospermia is found in 10-15% of infertile men and accurate judgment of the spermatogenic status of the testis is undoubtedly very important for the treatment of azoospermia patients. It can avoid unnecessary surgery, either definitive diagnosis or the prediction of sperm retrieval, and help with the adoption of assisted reproductive methods.

2．Epigenetic Effects of EndocrineDisrupting Chemicals in Male Germ Cell：

Endocrine disrupting chemicals (EDCs) interfere with the body function, affectinghuman reproduction and have gained wide attention. But the reality is thatpollutants can not be fundamentally treated and that the number of endocrinedisruptors is increasing. So, under the stress of EDCs, the molecular mechanism,especially at point of epigenetical view, of success of reproduction is urgentto study. Gamete imprinting gene is one of the possible candidate mechanisms forits "escape" of methylation erase.From anevolutionary perspective, all that will be help to reveal that, under EDCs stress,the gametic transmission strategy of imprinting genes epigenetic modification andthe possible molecular mechanism.
