Your career's on track, life feels a little more stable, and now the baby talk is starting to pop up. But where do you even begin? Whether you're just starting to think about having kids or already actively trying, being proactive about your fertility is key. Let's dive into the essentials.

When Should You Start Looking Into Your Fertility?

The answer: as soon as you're comfortable. Forget the notion that you have to struggle for a year before seeking answers. Your health is best managed proactively, and fertility is no different. If having children is in your future plans, it's never too early to check in on your fertility status.

Planning Ahead? Start with a Fertility Check-Up

If you're not quite ready to start a family but want to take proactive steps, have a conversation with your healthcare provider or connect with a fertility-focused naturopathic doctor (ND). These professionals can help you understand your fertility health and suggest ways to optimize it. This is also a good time to consider proactively freezing your eggs or embryos.

Actively Trying? Seek Guidance from a Specialist

If you've been trying to conceive and feel ready for some guidance, seek help from a reproductive endocrinologist (REI). They specialize in fertility and can give you a detailed, science-backed approach to your situation. The goal in either case is the same: take a holistic look at your fertility as a multifaceted puzzle.

Vetting Your Fertility Clinic Matters

When it comes to fertility help, make sure you're properly vetting your options. If you're part of the myStoria community, download the free guide Fertility Clinics 101: What to Ask & How to Advocate for step-by-step guidance on making the right choice.

Let's Talk About Hormones

One of the first tests you'll likely do is a Day 3 hormonal panel—done on days two to four of your cycle. It checks key hormone levels that reveal what's really happening inside: whether your last cycle wrapped up properly, how your body's gearing up to produce follicles, and more.

Assessing Ovarian Reserve

Another important hormone to check is AMH (Anti-Müllerian Hormone). When it comes to assessing ovarian reserve, AMH is the star of the show. People born with ovaries are born with all the eggs they'll ever have—we don't make new ones, and once they're gone, they're gone. Knowing your AMH levels helps your doctor determine how aggressive to be with treatment.

Progesterone: Your Ovulation MVP

Progesterone is usually checked 7 days after your suspected ovulation. If you successfully ovulated, this level should be elevated. Low levels might indicate a potential issue in your cycle.

Imaging: The Trans-Vaginal Pelvic Ultrasound

Usually done at the beginning of your cycle, this ultrasound checks your uterus, gives a snapshot of your ovaries, and calculates your Antral Follicle Count (how many eggs you're working with this cycle). It's a great starting point for understanding what's happening inside.

Inside Scoop: Checking the Uterus and Tubes

A Sonohysterogram or Hysterosalpingogram looks inside your uterus for abnormalities (like polyps, cysts, or lesions) and checks whether your fallopian tubes are open. The fallopian tubes are where egg and sperm meet, and the uterus is where your embryo needs to settle in—so making sure everything is in working order here is critical.

Male Hormones Matter Too

Just as we focus on the female side of fertility, male hormones are equally important. A hormonal panel can offer valuable insights into potential underlying issues. Abnormal levels of key hormones such as TSH and testosterone can highlight factors that may require further attention.

Sperm Assessment

The base test for analyzing sperm is a Sperm Assessment. This test evaluates sperm count, motility (how many are swimming), and morphology (how they look). If there's an issue with any of these factors, a DNA fragmentation test is worth exploring. This test checks the sperm's genetic material for damage, which can affect fertility and embryo quality. Importantly, a normal Sperm Assessment doesn't rule out fragmentation issues—so it's worth asking your doctor about this test from the start.

Uterine Microbiome: The Secret Tenants

Your uterus is filled with microorganisms—bacteria, yeast, viruses, and more—cohabitating together. If there's an imbalance (more harmful than beneficial), your uterus can become a hostile environment for an embryo, potentially inhibiting implantation or increasing the risk of miscarriage.

Immune System: Fertility's Silent Player

Your immune system can impact fertility in three ways:

  • Autoimmune issues: Your immune system attacks its own cells, which can affect fertility with or without a pregnancy.
  • Reproductive immunity: Your immune system reacts with your reproductive organs in ways that could harm fertility.
  • Alloimmunity: Your immune system responds to the genetic material of a fetus that's not entirely your own (like half your partner's genes).

All three can be assessed before conception so that steps can be taken to calm the immune system and improve your chances of success. Fertilysis offers at-home testing for both the microbiome and immune factors—no doctor or appointment required. myStoria community members have access to a special discount; reach out to ask about it.

Lifestyle Factors You Can Control

While fertility testing gives you a clear picture of your reproductive health, lifestyle factors can give your fertility a meaningful boost. A balanced diet, maintaining a healthy weight, regular exercise, stress management, and quality sleep all play an important role. Limiting alcohol, caffeine, and tobacco use is also key for both men and women—these habits can throw off hormone levels, reduce sperm quality, and impact egg health.

Final Thoughts

Fertility testing isn't one-size-fits-all, but being proactive is key. From hormone testing to imaging, sperm analysis, and the often-overlooked areas like the microbiome and immune system, there's a lot to consider.
