Finding out you or your partner carry a gene for an inherited illness has a way of changing everything, even before you’ve done anything about it. You can’t really un-know it. Suddenly you’re lying awake wondering, will my child be okay, is there anything I can actually do about this before I even get pregnant. That question, right there, is exactly what PGT-M was built to answer. At Dr. Mazen IVF Clinic, we sit with couples asking this every week.
PGT-M stands for Preimplantation Genetic Testing for Monogenic disorders. Bit of a mouthful, honestly, so let’s just talk about what it does instead of what it’s called. It’s a test run on embryos, before any of them are placed in the womb, to see whether they’ve inherited the specific faulty gene running in your family. Only the ones that come back clear get considered for transfer. That single step, on its own, can change how an entire pregnancy feels, not to mention what comes after it.
Why Couples Choose PGT-M
Some illnesses don’t come down to bad luck or how you live. They’re passed down through a single gene, quietly, sometimes for generations, and nobody notices until it shows up in a child. Thalassemia, sickle cell disease, cystic fibrosis, spinal muscular atrophy, certain types of muscular dystrophy, these are the ones we see come through our doors most. If both parents happen to carry the same faulty gene, or one parent carries a dominant version of it, the risk to their child isn’t some abstract statistic. It’s real, and it’s sitting right there in front of them.
Here’s the thing though, a lot of couples only find this out after something hard has already happened. A pregnancy that didn’t work out. A child who got sick. A family history that finally gets looked at properly for the first time. That’s partly why PGT-M matters as much as it does. Once you know the exact mutation, you get to act before the pregnancy even starts, instead of finding out mid-way and being handed decisions nobody should have to make under that kind of pressure.
It’s really why single gene disorder IVF has picked up so much here in the region over the last several years. And it’s not just about getting pregnant. Plenty of people can do that on their own. It’s about doing it with a lot less fear hanging over the whole nine months.

How PGT-M Actually Works
Step 1: Genetic counselling and mutation study.
Nothing medical happens until our genetic counsellors sit down with you and go through your family history properly, pinning down the exact mutation involved. That usually means a blood sample from you, from your partner, sometimes from a close relative too, so the lab can build what's called a genetic probe. It's built for your family specifically. You can't borrow someone else's, even if the disorder sounds the same on paper.
Step 2: IVF and embryo creation.
From here it looks a lot like regular IVF, egg collection, fertilisation in the lab, embryos developing over the days that follow. Dr. Mazen goes over the stimulation plan himself for every single patient doing PGT-M. Egg quality and how many embryos you end up with matter a lot more once genetic testing is in the mix, so he doesn't hand that part off.
Step 3: Embryo biopsy.
Once an embryo hits the blastocyst stage, usually day five or six, a small number of cells get carefully taken from the outer layer. Sounds a bit alarming when you first hear it described, but that part doesn't touch the cells that actually go on to become the baby.
Step 4: Laboratory testing.
Those cells head off to a specialised genetics lab and get checked against the exact mutation from step one. Embryo by embryo, this tells us which ones carry the faulty gene and which don't.
Step 5: Embryo transfer.
Once results land, we go ahead with an embryo that's clear of whatever disorder brought you to us in the first place. Anything else healthy that's left over gets frozen for down the road.
Start to finish, from that first appointment to having an embryo ready to go, it usually runs a bit longer than standard IVF. Most of that extra time isn’t wasted, it’s going into building and re-checking the genetic probe, because this isn’t somewhere anyone wants to cut corners on accuracy.
Dr. Mazen's Approach to PGT-M
Dr. Mazen has been working with families carrying inherited conditions for years now, and if you sat in on one of his consultations, you’d notice pretty quickly that he treats this as more than a medical appointment. He says it himself, this isn’t just clinical, it’s personal, sometimes it’s painful, and every family carries it a little differently. He’s not the type to hand someone a stack of lab results and call the job done.
Before anyone moves ahead with PGT-M Dubai families sit down with Dr. Mazen directly, not a quick five minute rundown squeezed between appointments, but an actual conversation, so people walk away understanding what the test can tell them and, just as important, what it can’t.
He’s also honest about something a lot of clinics tend to skip over. PGT-M lowers the risk. Dr. Mazen works directly with accredited genetic labs and goes over each case himself to figure out the right timing for the biopsy and the right lab for that specific disorder. Nothing about it is one size fits all, and he doesn’t run it that way.
Patients bring this up a lot actually, that it feels like one doctor is walking with them the entire way, rather than getting bounced between departments and having to repeat their story to someone new every visit. When you’re dealing with something this sensitive, that kind of continuity ends up mattering more than most people expect going in.
What About PGT-M Cost in Dubai?
This is usually one of the first things people ask, and fair enough, it’s a real consideration. PGT-M cost in Dubai comes down to a few moving pieces, the IVF cycle itself, how many embryos get tested, and how involved it is to build a genetic probe for your specific mutation. Some conditions already have a tested protocol sitting ready, which can keep things a little cheaper, while rarer or newly identified mutations sometimes mean extra lab work to build a custom probe from the ground up.
At Dr. Mazen IVF Clinic, we lay the cost breakdown out clearly before you commit to anything, so there’s nothing sprung on you halfway through treatment. And if your case happens to qualify for a simpler or quicker path, we’ll say so upfront. You’re already carrying enough on your shoulders through this. Worrying about hidden costs shouldn’t be one more thing on the pile.
Who Should Consider PGT-M
Worth thinking about PGT-M if any of this sounds familiar:
- You or your partner have already been confirmed as a carrier of a genetic condition
- Someone close in your family has a known inherited disease
- You’ve had a child before affected by a single gene disorder
- You come from a background where certain genetic conditions show up more often
- A carrier screening test has already flagged something for you or your partner
