• The Science of You

    In the simplest terms, fertility is the ability to make a baby. That means producing fertile eggs. This might feel like a given, but age, genetics, and other factors impact your fertility.

    Let’s keep learning . . .

Egg Production & Ovulation

Eggs and Follicles

Follicles are protective sacs that hold your eggs. They only release an egg when well developed. Follicles are also sensitive! They’re impacted by age, self-care, and diet. We’re experts in properly encouraging follicles to develop and release your eggs (a.k.a. ovulate).

Ovulation

When a follicle releases an egg, that’s called ovulation. In a regular monthly period, only one follicle matures enough to release an egg. In the egg freezing process, we stimulate and develop many follicles so that multiple eggs are released in a single cycle.

From Egg to Ovulation

Times have changed. Biology hasn’t.

As you age, the number and quality of your eggs decline. Fertility begins to decline

at age 32, and accelerates in your mid 30’s. By 44, it is exceedingly difficult to

conceive, even with advanced treatments like IVF.

Amount

Higher number of eggs = higher chance of fertile eggs… simple enough odds. You’re born with all the eggs you’ll ever have. As you age, your eggs’ genetics change and some of them become less viable,

Potential

There are several factors at play in each of us that we take into account. Based on the results of your hormone testing, we can set expectations for the egg retrieval process.

Ovarian Reserve

To determine the quantity and quality of the eggs we have left, a.k.a. ovarian reserve, we test for AMH (Anti-Mullerian Hormone) which is made by cells inside of our follicles.

Hormone Spotlight

So what’s responsible for all this and how do we control fertility and follicle development?

Here’s the who’s who of follicle development influencers (aka hormones). Hormones deliver messages within the body. These messages control all kinds of processes from hunger to mood to the intricate reproductive system within you.

Hormones, by what they do, also tell your Preserve fertility experts how to map out the best fertility path for your individual needs.

Anti-Müllerian Hormone [AMH]

Anti-Müllerian Hormone is a protein hormone. It’s made inside the ovarian follicles and helps us estimate the number of follicles you have inside your ovaries, or ovarian reserve. In this way, AMH levels reveal crucial information about your fertility.
