[QUOTE="Bright Raven, post: 1462507, member: 27490"] [b]The pregnancy results suggest that IVF embryos result in diminished rates compared to traditional. 50 % +or - 5 % is about the expected rate. Traditional embryos are generally at least 5-10 % higher. IVF procedures do allow one to circumvent some common obstacles such as use of rare and expensive semen, cows not responding to traditional stimulation protocols and the most desired feature- reverse sorting for all females. The recent availability of sexed semen from Sexing technologies ( doing better than sex semen previously) could eliminate the need to reverse sort.[/b] Dr. James Spears, American Embryo Transfer Association. The viability is not significantly lower. My understanding is that the cost is higher. [/QUOTE]
