Fertility rates are on the decline, this is true. Martin O'Connell, chief of the fertility statistics branch of the Census Bureau, said the changes in the last nine years, though significant, were rather small when compared with earlier decades. In 1960, he said, the rate was about 120 births for every 1,000 women of childbearing age; in 1970, it was about 90. Thus, he said, ''The fertility rate now is about half what it was in the late 1950's and early 60's.'' There are many environmental factors contributing to why, including pesticides in our foods, chemicals and pollutants in the air, wireless radiation, and the growing number of women choosing to have children at a later stage in their lives. Stress, however, a clear link to the mind/body connection, may very well be the most overlooked contributor to infertility.
More and more IVF clinics are inclined to implant developing eggs at the day 5 over day 3. What are the reasons? And what is the basis on which one to chose?
Pro:
On a most basic level 25% of 3 day embryos are normal vs. 65% of 5 day, which are now a blastocytes, are normal. Most clinics want to have the highest success rates possible. People chose to come to a clinic based on its success rates. So there is a survival mechanism to one element. That is one of the reasons they have an age limitation to whom they will work with. At some point it is against the odds that you will conceive.
