  • The expression level of C19MC miRNAs in early pregnancy and in response to viral infection. 
  • The significance of hydrosalpinx in in vitro fertilization. 
  • Transfer of cryopreserved-thawed pre-embryos in a cycle using exogenous steroids without prior gonadotrophin-releasing hormone agonist suppression yields favourable pregnancy results. 
  • Transfer of cryopreserved-thawed pre-embryos in a natural cycle or a programmed cycle with exogenous hormonal replacement yields similar pregnancy results.
