Time-lapse recordings reveal why IVF embryos are more likely to develop into twins

..., either a decision could be made about whether to transfer those embryos that are likely to give rise to twins, or, if the choice of embryos is limited, the mother could be prepared for the likelihood of twins and given appropriate clinical advice. In addition, more information about the cause of monozygo...

New approaches to endometriosis treatment -- mouse experiments point the way

...mple, suggests that endometriosis constituents may transfer into tumour cells. If we are able to inhibit angiogenesis in the ectopic human endometrium with a dopamine agonist, says Dr. Novella-Maestre, we may be able to decrease the cancer risk for these patients. In another presentation to the conference...
