You’ve probably heard it before, maybe from a friend or online, “You should freeze your eggs while you still can.” It often comes with urgency, but pressure without clear information doesn’t make this decision any easier.
If you’re a woman in her 30s, you might feel caught in between. You may not be ready for a child right now, but you know fertility changes over time. That awareness can sit quietly in the background, or feel more present some days.
At King Square Fertility, many women come in looking for clarity, not pressure. Egg freezing, or oocyte cryopreservation, can offer flexibility, but it’s not a guarantee and isn’t right for everyone.
This guide is here to give you clear, honest information so you can decide what feels right for your life and your timeline.
The conversation around egg freezing in your 30s often centres on age, because biology operates on its own schedule.
We’re born with all the eggs we’ll ever have. Over time, the ovarian reserve or the number of eggs left, declines. More importantly, the quality of those eggs changes as well.
By your mid-30s, this decline begins to accelerate. According to the Canadian Fertility and Andrology Society (CFAS), the chance of a healthy pregnancy is statistically higher when eggs are frozen at a younger age.
This doesn't mean you should panic; it simply means that if you choose to preserve fertility, the eggs you freeze at 32 are more likely to result in a healthy pregnancy later than those frozen at 39.
If you’re considering this path, it helps to know that the process is a structured medical journey. It requires time and physical preparation, but most people find it very manageable with the right support.
Before anything else, you’ll meet with a fertility specialist to discuss your goals and review your medical history.
You’ll also undergo baseline fertility testing, which typically includes bloodwork to measure hormone levels (such as AMH, or anti-Müllerian hormone) and a transvaginal ultrasound to count the small fluid-filled sacs in your ovaries that contain immature eggs.
These tests give your care team a sense of your ovarian reserve. They help predict how your body might respond to stimulation medications and how many eggs might be retrieved.
This is also the stage where you can ask questions. How many eggs should you aim to freeze? What are the realistic outcomes based on your age and test results? What are the costs involved? A good fertility clinic will give you honest, personalized.
If you decide to move forward, the next step is ovarian stimulation. For about 10 to 14 days, you’ll take hormone injections that encourage your ovaries to produce multiple eggs in a single cycle.
Normally, your body releases one egg per month. The medications override that process temporarily.
Some women experience bloating, mood changes, or mild discomfort during stimulation. Most side effects are manageable, but it’s worth being prepared for a couple of weeks where your body feels different than usual.
Once your follicles have matured, the retrieval procedure is scheduled. This is done under light sedation and typically takes about 20 to 30 minutes.
A needle, guided by ultrasound, is used to aspirate the fluid from each follicle. The eggs are then identified, evaluated, and frozen using vitrification, a rapid-freezing technique that preserves the eggs' cellular structure.
Most women go home the same day and return to normal activities within a day or two. Some experience cramping or light spotting afterward.
Your frozen eggs are stored in a specialized facility until you’re ready to use them. When, or if, that time comes, the eggs are thawed, fertilized with sperm through a process called intracytoplasmic sperm injection (ICSI), and transferred to your uterus as embryos.
Not all frozen eggs will survive the thaw. Not all will fertilize. Not all embryos will implant. This is why fertility specialists often recommend freezing a certain number of eggs depending on your age and goals, to improve the odds of at least one successful pregnancy later.
There’s no standard reason to choose this path. Every patient we meet has a unique story:
The cost typically includes the medical procedure, medications, and annual storage fees. While prices vary, you can expect the procedure and medications to range from $10,000 to $15,000.
Thankfully, you can benefit from funding from the Ontario Fertility Program. It’s also worth checking if your workplace benefits cover fertility preservation.
Eggs can be stored indefinitely. The length of time they are frozen does not impact their quality or the health of a future pregnancy.
Many women who freeze their eggs never end up needing them because they conceive naturally. If that happens, you can continue to store them, donate them to another hopeful family, or have them discarded.
There’s no universal number, but most fertility specialists recommend freezing at least 10 to 15 mature eggs if you’re under 35, and potentially more if you’re older.
The goal is to account for the natural attrition that occurs during thawing, fertilization, and implantation. Your clinic can give you a more personalized estimate based on your test results.
The injections can cause mild discomfort, and some women experience bloating or tenderness during ovarian stimulation.
The retrieval itself is done under sedation, so most women don’t feel pain during the procedure. Cramping afterward is common but usually resolves within a day or two.
If you’re thinking about egg freezing, the most empowering thing you can do is move from "wondering" to "knowing." You don't need to decide to move forward today; you only need to decide to gather information about your own body.
