" Fertility is a complex puzzle. Diet, stress, movement, toxins, hormones, they all matter. When we address each piece, that’s when we start seeing incredible outcomes. That’s why I love what Fibra is doing with cycle and temperature tracking, it brings the full picture into focus. "

" The fertility journey is stressful and often invasive, from medication to needles. That's why I believe Fibra will help alleviate both the physical and mental stressors, allowing women to feel like it’s just a natural part of their day rather than another burden to manage. "

i think your product as soon as i saw it i'm like oh this is gonna allow women to feel like it's just part of their day, it's not an additional mental thing you have to take on. knowing your fertility window, what your cervical mucus looks like. i'm really excited about that, alleviating those pain points those physical and mental stressors for people. i'm excited to see how this is working its a very exciting technology - the ability for women to know what’s going on in their body. it’s non-intrusive and respectful and it aligns with our comfort levels and takes away that stress and i’m excited to see where it goes and how it’s going to impact all the women out there.

I know firsthand how important it is, and it’s actually very amazing and exciting what you are doing giving that control to women to be able to monitor the status of their hormones and what’s going on in their bodies on an app in their phone without having an invasive method of trying to get those results; just with a simple normal underwear. This is something for women in all stages of their life, not just for PCOS or women trying to conceive. It’s a holistic view of what’s going on in your body, i’m excited and eager to see the product in the market.

It’s a high-tech underwear that’s easily connected to an app on your phone and it’s basically giving you a personal fertility and hormone tracker 24/7, so that’s what I love about it. So now you have something that’s in your underwear drawer that you can use to work with your doctor or someone in nutrition, it works alongside any fertility treatments you're doing, it’s an enhancement. It gives you personalized tips on your diet, lifestyle and it’s not a one size fits all, it's personalized to your body.

I really commend what you're doing with fibra because its very important to get that information out there, to provide tools that will help women track more data on their reproductive health. you're creating lots of education and awareness and that’s exactly what communities and women need.

I think what's great about FIBRA, it's another tool in our toolbox to understand what's happening with your fertility. So if we're tracking temperature or tracking heart rate variability, we can understand what's happening in the cycle. Fibra is just paving a pathway for information And I think there's so much more scope that we will see from it. There's so much more data that we'll be able to get. I think looking at vaginal discharge is something that isn't being done, and I'm excited to see what information we are going to get from vaginal discharge data.
Erin Fordham
Erin FordhamCo-Founder & President - Oasis Fertility Support Network
I'm a big believer in making life easier. If there is something that can make my life easier, I'm here for it. And so I think fibra has the potential to be just a beautiful and empowering companion for anybody who's trying to conceive, especially in the early stages when, you know, before they're in clinic settings or, I mean, even alongside treatment plans I think we can actually use it as a tool to, like, you know, be more, productive at certain times of the month, be more athletic at certain times of the month. the problem with other apps is they are extremely generic. So they take a very, generalized algorithm, and they apply that to every single woman on Earth. Women who have, PCOS and endometriosis, I have PCOS too, and my app is never accurate for me. You can get women into these underwear when they're young or when they're, like, learning about their bodies and using that education to lead to early action, better planning, fewer surprises, you know.
