What if I have an ‘out of range' result?

I often meet people who are interested in their hormonal health and fertility, but who don’t want to do a Grip test because they’re worried about the consequences of a bad result.

I get it - it’s scary to think about your fertility. What if it turns out you can’t have kids?

To start with the most common misconception: the Grip test won’t tell you if you can or cannot have kids. There is no absolute predictor for fertility, and there’s also no absolute predictor of infertility. We can’t tell you that you’ll definitely never have a baby, and neither can any doctor. Same goes for being able to predict how long it will take for you to get pregnant. Think of your Grip test as a risk profile, rather than a yes or no answer. If you know your risks when you’re still young, you still have all options to do something about them.

In order to give you some idea of what to expect, we looked at the (anonymised) results of everyone who’s taken a Grip test so far.

What does the data say?

By now about 750 people have taken a Grip test. 436 of them (about 57%) have results that show that as far as we can tell, there’s nothing to worry about. This also means that 314 women have received results that mean it’s worth further investigation.

The three most common ‘bad results’ we see are an increased risk of PolyCystic Ovarian Syndrome (PCOS), an under-active thyroid, and lastly a low ovarian reserve.

Grip results as of February 2021

Two things to keep in mind:

  1. a flag in your hormones doesn’t mean a diagnosis: it’s just a reason for you to do some extra digging into what might be causing your values to be out of range. As a result, we’re likely to err on the side of caution and likely have more ‘bad results’ than that there will be eventual ‘bad diagnoses’.

  2. we expect that our early customers are likely the ones who have been having issues for a while, and are therefore more likely to have ‘out of range’ results. These numbers aren’t representative of the general population!

Below we’ll give you a brief overview of each of these 'abnormal' results, show you an example report for each, and explain what you can do once you know.

1. Your report says you have an increased risk of Polycystic Ovarian Syndrome (PCOS).

21% of the women we tested at Grip so far had an increased risk of PCOS based on their hormones. This makes it the most common ‘bad result’ we see. There’s been several studies that estimate that 10 to 20% of the female population suffers from PCOS, so no surprises there (Pal et al, 2014). PCOS makes your ovulation (and therefore your periods) irregular, and sometimes even stops you from ovulating at all. Having PCOS does not mean that you won’t have kids. It’s harder to time sex right when you ovulate irregularly, and if you don’t ovulate at all you’ll likely need medical help to get pregnant.

You can see an anonymised but real ‘possible PCOS’ Grip report here.

“I remember having bad periods when I was very young, but I’ve been on the pill since I was 14. Once I stopped the pill, I wasn’t sure if my irregular periods were the result of lingering pill-effects, or if something else was up. After taking the Grip test and seeing how high my AMH and testosterone levels are, I know that it’s a lot more likely that I have PCOS.

What are the next steps once you have a possible PCOS report?

We always recommend you to go see your GP once you suspect you may have PCOS. You’ll likely need an ultrasound to get an official diagnosis. We won’t lie: PCOS sucks, and there’s a lot more research needed on how we can treat it.

The important thing to keep in mind here is that it on average takes 2 years and 3 different doctors to get a PCOS diagnosis (Gibson-Helm et al, 2016). Once you know what is happening, it will take another while to get the syndrome under control so that you have the best possible chances when trying for a baby. ‘Losing’ 3 years sucks when you’re 28 and feel ready to conceive, but imagine what happens if you’re 38 by the time you find out. If you only have a couple of years to get pregnant left when you get your diagnosis, the effects can be heartbreaking. Knowing you have PCOS early, and being able to adjust your lifestyle and expectations accordingly, really matters.

2. Your report says you might have an under-active thyroid.

4 out of every 100 Grip customers so far has had an indication of a slow thyroid. Research suggests that 1 in 6 women will deal with a thyroid issue at some point in their life (American Thyroid Association, 2014). Your thyroid is responsible for a bunch of processes in your body, including your metabolism and your fertility. People with a slow thyroid often take longer to get pregnant, and have an increased risk of miscarriages (Krassas et al, 2010). Symptoms related to an under-active thyroid can be tiredness, weight gain, and feeling depressed.

We test TSH, which is only one of the hormones that determines your thyroid function. A raised TSH is a first indication that something might be wrong, but you’ll need more tests to determine exactly what.

My cofounder Ling knows she has a (slightly) under-active thyroid. You can see her report here.

“I didn’t recognise myself in the symptoms associated with a slow thyroid, but after additional analysis at my GP it turns out it is indeed slow. My fT4 was only mildly raised, and so I’m trying to adjust my lifestyle for the next 6 months to try and get it down. If it doesn’t work, my GP will start me on meds. I’ll definitely make sure to have it under control before I start trying to get pregnant.

What can you do once you have an under-active thyroid report?

If your TSH is elevated, you’ll need additional thyroid analysis at your GP. We expect that your GP will at least want to check the hormone fT4, and maybe fT3.

If it turns out that your thyroid is indeed slow, you’ll likely be prescribed medication to fix the imbalance. There’s also certain lifestyle changes that you can try if the imbalance is small. Thyroid imbalances are relatively easy to fix, and having a balanced thyroid can make a hugely positive impact on your life and wellbeing.

3. Your report says that you are likely to have a low ovarian reserve.

5% of the women we tested at Grip seem to have a low ovarian reserve. Your ovarian reserve is a fancy way of saying how many eggs you have left, and what is considered a normal amount of eggs changes as you get older. The hormone AMH is the most reliable predictor of your ovarian reserve (Iwase et al, 2015). We define a ‘low amount of eggs’ as being in the 0-5% category of women of your age. This means that 95% of the women your age have a higher amount of eggs.

We can’t stress it enough: how many eggs you have says very little about how likely you are to get pregnant naturally right now. In fact, women with a low ovarian reserve (AMH <0.7 ng/ml) are just as likely to fall pregnant within 12 months of trying as women with a normal ovarian reserve (AMH between 0.7 ng/ml and 8.4 ng/ml) (Steiner et al, 2017).

See an example Grip report of someone with a low ovarian reserve (AMH) here.

What can you do once you have a low ovarian reserve report?

The main reason why knowing you have a low ovarian reserve matters is because it helps you understand when you’re likely to enter menopause. If you know you’re at risk of going into menopause earlier than average, and you really want to have kids, then you might want to decide to start trying for kids younger. If that’s for whatever reason not possible, then you can consider trying to preserve your fertility via egg- or embryo freezing.

Your ovarian reserve isn’t particularly important for getting pregnant naturally, but it does have important implications for getting IVF or freezing your eggs (Broekmans et al, 2006). The first step of treatment for both IVF and egg freezing are the same: a doctor will use medication to ‘stimulate’ your ovaries, and effectively trick your body into releasing multiple eggs for fertilisation rather than one. People with a high ovarian reserve tend to ‘yield’ more eggs per round of treatment than people with a low ovarian reserve. That doesn’t mean they also get more viable eggs frozen, because AMH says nothing about egg quality. There’s certain hospitals and clinics who have a minimum AMH threshold for fertility treatment, but more importantly: if you know you have a low ovarian risk and you want to freeze your eggs, the age at which you do so really matters. When you’re younger, you’ll have more high quality eggs, and therefore more viable frozen ones, even if your ovarian reserve is low (Chang et al, 2018).

There’s no ‘cure’ for a low ovarian reserve, and the biggest influences are age and genes. Smokers enter menopause on average 2 years earlier than non smokers, so you may want to quit doing that (Sun et al, 2012).

“My mum entered menopause when she was mid 40s, and so I’ve always been worried about my fertility. My Grip test told me my AMH is currently 0.8 ng/ml. That’s not crazy low, but I don’t see myself having kids before I’m 35.
I started looking into egg freezing, and will start my first round of retrieval in 3 months. I’m really glad that I found out about my ovarian reserve whilst I am still young and my eggs are high quality. Grip has moved up my timeline. I think it’s likely that I’ll still try to get pregnant naturally once me and my boyfriend are ready, but I feel reassured knowing that I have the option to take control of my future.

As a reminder: everyone who gets their Grip results doesn't just get a report, but also a free video consultation with one of our doctors, to make sure you really understand what your report says.

We really care about making sure you can make better choices because you understand your body better. Fertility isn't one size fits all, and it's time we acknowledge that.
