Interestingly, none of the opponents of embryonic stem cell research have called for research programs that might increase the odds
of embryo survival.
Among other important nutrients, they contain folic acid, which numerous studies have found to be critically important for baby at every stage of development — it helps promote ovulation, encourages fertilization and support
early embryo survival, says Audrey Gaskins, ScD, an instructor of nutrition and dietetics at Harvard Medical School.
«Additionally, after assessing the genetic quality of the males we
found embryo survival was linked to being sired by higher quality fathers,» she says.
Some of those matching genes are vital
for embryo survival, including several responsible for cell communication, cellular energy and adhesion to the lining of the uterus.
Poor survival of in vitro embryos may have contributed to the pessimistic view about natural
human embryo survival, says Dr Jarvis.
Rosengrave P, Montgomerie R, Gemmell N. Cryptic female choice enhances fertilization success and
embryo survival in chinook salmon.
Researchers from New Zealand's University of Otago studying chinook salmon have provided the first evidence that «cryptic female choice» (CFC) enhances fertilisation success and
embryo survival.
