Hello friends, and welcome back to the As A Woman podcast. I'm your host, Dr. Natalie Crawford, and I am so excited to be sharing one of my favorite topics with you today.

We are going to be talking about tracking ovulation, and specifically ovulation predictor test.

These tests, I have an interest in, as many of you know, I'm a fertility doctor, and when we do our fellowship in reproductive, endocrinology, and infertility,

we have to do three years of fellowship training, and that's after four years of OBGYN, and in that three years, a year and a half is research.

So any fertility doctor that you see walking around who went to an REI fellowship actually did a significant amount of research.

That's really important for two reasons. One is because this field changes all of the time.

In a field that constantly changes, you have to understand how to evaluate studies that come out. Are they good? Are they bad?

What can you take from this? How can you change your practice? What should you not be doing?

And we also have to have a fine, fine balance of understanding that sometimes the field moves faster than the evidence and being able to critically assess what is out there.

Well, that was all very long-winded to say that I use it all of my fellowship research on natural fertility, and that's why I have such an interest in fecundability.

If you're new here, welcome. Fecundability is the chance of getting pregnant per month, the probability of pregnancy per month.

And we consider that one of the most finite markers when looking at fertility studies, because the reality is, what's your end point?

Is it a positive pregnancy test? Is it a clinical pregnancy, meaning seeing a gestational sac or fetus inside the uterus?

Is it a heartbeat? Is it getting to term? Is it having a baby? There's just different outcomes that studies use.
