Blastocyst Transfer vs. Day-3 Transfer: What the Research Shows

When you are preparing for an embryo transfer, one of the biggest questions your care team will ask is when the transfer should happen. Should the embryo go back on day 3, while it is still a small cluster of dividing cells? Or should you wait until day 5 or 6, when it has grown into a blastocyst with hundreds of cells organized into two distinct layers? The answer shapes your timeline and your odds of a successful pregnancy, and it is worth knowing before you sit down with your...

What It Means to Be Treated at a Female-Led Fertility Clinic

  Fertility treatment touches something deeply personal, and it can feel overwhelming to hand that experience over to a stranger. Every appointment, blood draw, and hormone level can carry a mix of hope and worry, and the person guiding you through it shapes how safe and heard you feel along the way.

Can You Do IVM if You Have PCOS? What the Research Shows

  Getting a diagnosis of polycystic ovary syndrome alongside a fertility diagnosis can feel like being handed two problems instead of just one. Many women in this position ask the same question early on: is in vitro maturation even an option, or does PCOS rule it out before treatment can start?

What to Know About Egg Donation Eligibility Requirements in Brazil

At Chedid Grieco, eligibility is treated as a safeguard, not a formality.

At Chedid Grieco, we now offer in vitro maturation, or IVM, as an alternative path to fertility preservation alongside traditional...

At our human reproduction laboratory, every hour after retrieval is documented, monitored, and explained back to you in plain language. Chedid Grieco has spent 30 years refining this process, and this...
