Human Fertilization - Fertilized human egg pictures from IVF, in vitro fertilization

One-cell embryo, also called a zygote, or a two pronuclear embryo

Picture of IVF fertilized egg at high magnification
Male and female genetic material (DNA) is in the 2
pronuclei (circular structures) in the center
Polar body is seen at one o'clock - just under the shell

  • The (ovarian) cumulus cells around the egg (see egg images) have been stripped off
  • This is what we see at the "fertilization check" the morning after the IVF egg retrieval procedure
  • Evidence of fertilization is shown by the presence of the 2 pronuclei in the center
  • Without fertilization, the egg would look the same, but without any pronuclei
  • When 3 pronuclei are present instead of 2, then it is a triploid zygote - which has an extra set of 23 chromosomes - and can not make a normal baby.
  • A fertilized egg is also called a "zygote", a "1 cell embryo" or a "2 pronuclear embryo"

TESTIMONIALS

profile

I am so grateful for Advanced Fertility Center. I just had my son Leland. I want to thank Dr. Catenacci and all of the nurses that helped us. Especially Ashley in the Crystal Lake office. You made this process easier by being supportive and positive. Thank you very much!

Dr. Sherban and his staff are the most amazing, compassionate, and supportive people. After almost 5 years of trying to conceive, going through numerous tests and meeting with another clinic closer to home, who told me my chances even with IVF were still very low, a good friend recommended advanced fertility center of Chicago. Best decision we ever made! We now have 2 amazing children who are now 5 and 3 years old! I cannot stress enough how amazing this staff is, they make you feel like family!

Our experience was amazing with Dr. Cantanucci and all of the nurses (especially Ashley). After ttc for 4 years and at 41 years of age, we became pregnant after 1 round of IVF, and had our beautiful boy this past October. Can't thank them enough!

Thank you advanced fertility!
