The probability of success with IVF treatments depends upon a number of factors like the age of the woman, the causes of infertility, the quality of eggs retrieved and the quality of the semen. I do have my IVF experience. The single most consistent variable affecting ovarian reserve is the woman's age. I do have my IVF at the age of 30. In most woman in their 20s about 2/3 of the eggs are genetically normal or balanced. However, there will be some that are genetically abnormal or unbalanced. It appears that the best eggs are ovulated first. The older a woman is, the fewer genetically balanced eggs she has left to respond to fertility drugs. This egg relationship holds true even in the fertile population. At age 35, about 40-50 % of eggs are chromosomally normal. At age 40, about 10-20 % and then much fewer after that. Therefore, in older woman fewer normal embryos are available for implantation into the uterus. Hence, healthy woman over 35 are less fertile than their young counterparts. woman 40 and over may have only a 20% live birth rate with IVF treatment using their own eggs, even though several embryos are placed into the uterus.

Your English is good. However, the plural of "woman" is "women".
The need to place multiple embryos in the uterus of any woman is growing obsolete. It's too risky for the mother and offspring.
Avoid IVF and surrogacy in Ukraine. Ukrainian centers pay shills to post here under numerous sock accounts pretending to be patients in Ukraine. Centers using such deceptive advertising cannot be trusted and should be avoided.
I am no specialist. and I completely support the idea of using fewer embryos. I have heard that it is a common practice to place 1 or 2 embryos all over the world. but i have also read the stories about women giving birth to quadruplets or so. but as far as i know, this is incredibly dangerous. and the babies have higher chances to be born with some diseases.
which is why we have specifically required up to 2 embryos transferred when signed with WCOB
