A PSA for the Ladies: Plz Know More About Your Fertility Than These Men Do…

Men are cute. And often, they’re great.

But let’s face it—males are probably not the best source of info on your fertility. Heck, many of us women don’t know all the ins and outs of our fertility, either!

We have compiled some highly scientific proof:

Glow knows. And that doesn’t make your man any less fine!  In fact, with Glow, you’ll both be prepared for smart sex: the best kind ;)

Glow officially knows a thing or 2

Glow is 2! That’s right. We just had a big b-day. There was cake cake cake. And while riding the sugar high, we took a deep dive into our epic data set to see what we could find.  

Turns out, we’ve collected a lot of interesting tidbits! We just had to spill. Et voilà—check out what we can show the world after two years of getting it on :)

Prevention is the Breast


It’s October and the pink ribbons have descended: Breast Cancer Awareness month is upon us!

When dealing with the threat of breast cancer, it’s important to know what you personally can and cannot control. Glow’s here to help with two lists. 5 breast cancer lifestyle choices well within your control. And 5 breast cancer risk factors out of your control. Get ready to turbo-charge your breast cancer savvy :)

5 Breast Cancer Awareness Tactics Well Within Your Control

  1. #YOLO - You only live once, so take care of that body. Stay in control when it comes to alcohol (no more than one drink per day is best advised), stay away from those cigs and all smokey smoke. Remaining physically active and in a healthy weight range will also help!
  2. Breast-feed - If you’re a baby momma, know that breast-feeding may play a role in breast cancer prevention. The longer you breastfeed, the greater the protective effect.
  3. Genetic testing - Genetic testing can identify mutations in genes that increase breast and ovarian cancer risk (like BRCA1, BRCA2, and 19 others). If the test shows that a mutation is present, that does not mean that you will definitely contract breast cancer! Instead, it is a sign that you should talk to your doctor about getting screened for breast cancer more frequently. Genetic testing can be expensive, but this October, Glow partnered with Color Genomics to offer free genetic testing for breast & ovarian cancer to all employees. Thanks, Glow! <3
  4. Mammograms - The American Cancer Society just changed its recommendations, and now advises that women should start getting annual mammograms at age 45. 
  5. Limit hormone therapy - Hormone therapy was once routinely used to treat menopausal symptoms and protect long-term health. Then large clinical trials showed health risks. And one of the health risks is that undergoing hormone therapy for more than 3-5 years increases the risk of breast cancer. Avoid hormone therapy if you can.

5 Breast Cancer Risk Factors Outside Of Your Control

  1. Your vagina - Kind of, not really. But simply being a woman is the main risk factor for developing breast cancer! It is possible for men to develop breast cancer. That said, breast cancer is ~100x more common among women.  
  2. Aging - Breast cancer risk increases with age—about ⅔ of invasive breast cancers are found in women age 55 or older.
  3. Genetics & Family History - About 10% of breast cancer cases are thought to be hereditary, the result of gene defects (called mutations) that are passed down from a parent. Having a mother, sister, or daughter suffer from breast cancer almost doubles a woman’s risk :(
  4. Breast density - Yes this is a thing. So breasts are made up of fatty tissue, fibrous tissue, and glandular tissue. The less fatty tissue, the more dense the breasts are. Dense breast tissue makes mammograms less accurate and increases risk of breast cancer. Boo.
  5. P-p-p-periods galore - Women who have had more menstrual cycles because they started menstruating early (before age 12) and/or went through menopause later (after age 55) have a slightly higher risk of developing breast cancer.

Bring it on, pink ribbons.  The more we discuss and share, the more we become aware.

Your Period By The Numbers

We women spend a lot of time menstruating, as it turns out.

The DL on Vaginismus

You’re finally in bed with him. The moment is perfect. He’s is so obviously ready and you are, too. You want it, you crave him. But your body has other ideas: Your vagina is a steel door, shut tight. Any pressure leads to pain. No matter what you try, everything hurts…

It’s common to hear men say they couldn’t get it “up.” But how often do you hear a woman bemoan that she couldn’t get it “in”? Women who have had sex so painful that they needed to stop could be experiencing a condition called vaginismus.


Vaginismus is an involuntary contraction, a tightening of the pelvic floor muscles that generally occurs when an attempt is made to insert an object (penis, tampon, finger, other stuff…not judging promise) into the vagina. Some have vaginismus from birth; others develop it after a period of normal sexual intercourse. For those who have it, sex can be extraordinarily painful.

Pain during sex is more common than an erotic novel lets on. We asked our community via a Glow poll, and over 5500 women responded. 43% of respondents reported that penetration during sex hurts at least some of the time; 3.5% of respondents said that sex hurts every single time.  

Because pain during sex is so common, it’s pretty much impossible to tell who suffers from vaginismus specifically. Many women are shy to bring up painful sex with their partner or with medical professionals. Sex is supposed to be fun, exciting, a way to express love and connection—and admitting that it is not delivering in these ways can be difficult in today’s world. As such, many cases of vaginismus likely go unreported. Research suggests that anywhere between 2 to 70 out of every 1000 women could be affected by vaginismus, which is quite a wide range.

Wanna know the good news? Vaginismus is actually quite treatable! No magic pill, unfortunately—it takes time and effort—but a regimen of floor exercises, insertion or dilation training, and pain elimination techniques can help alleviate sexual pain overtime. Much of this work can even be done at home.

Sex doesn’t need to be painful forever. If pain during sex is frequent enough that you think you may have vaginismus, start speaking up about it. Chances are, it’s possible to transform your sex life into a happily ever after—an erotic novel with the ending you deserve :)

Ruby –> Eve!


Our wild child, Ruby, is already rebelling. <sigh> From this day forward, she wants to be known only as Eve by Glow.

That’s right—we’ve changed the name of our app. Ruby is now Eve by Glow.

Eve has everything you <3ed about Ruby: sex tracking, cycle trends, the scoop on all things birth control. In fact, Eve is even more of a catch! Think 29 INPUTS, including the ability to log sex with non-male partners, the ability to rate the sex you have… and yes, you can now log sex the morning after. No need to do it the night of, because that’s awkward.


Kiss Ruby goodbye, and download Eve by Glow!

“O” Know: All About the Female Orgasm

Let’s be honest—there is nothing terribly subtle about the male orgasm. But for us girls, it’s more sophisticated (no surprise there).

Women report all sorts of orgasms: orgasms from clitoral stimulation, orgasms during vaginal stimulation, “birthgasms,” orgasms from kissing, from nipple-touching, fake orgasms, you name it. What’s going on here?!?


The answer hinges on a solid understanding of female reproductive anatomy. The clitoris is not just a “pea-shaped bobble ” under the surface of the skin. No, no—that’s just the tip of the iceberg. The full clitoris is actually quite large (9 cm in length!) and loops all around the inside of the vagina, alongside the urinary tube, the urethra. The clitoris is made of tissue similar to the erectile tissue in the penis, but different in that female clitoral tissue can respond directly to hormones like estrogen. Yet another instance of the female body displaying its superior qualities :)

Why do some women orgasm during vaginal penetration while others do not? Because #anatomy. Clitoral tissue extends internally for all women. Some women have more of these internal portions of the clitoris exposed to the vagina—these women are much more likely to orgasm during vaginal penetration. Alternatively, other women have thicker tissue in the space between the vagina and urethra, which makes the clitoral tissue less prone to stimulation via vaginal penetration alone. So it goes.


If you have yet to hit the big “O” from vaginal stimulation, do not despair. There is nothing “wrong” with not being able to orgasm this way—in fact, a Glow poll revealed that only ~6% of women climax from vaginal penetration alone, compared to ~51% who orgasm from clitoral stimulation alone.

Consider these numbers an invitation to take matters into your own hands (so to speak) to learn what you like best. Consider checking out the “How To Make Me Come” blog which describes women’s individual experiences with orgasms, or Sophia Wallace’s “Cliteracy” movement which aims to challenges the lies, question the myths, and rewrite the rules around sex and the female body.

Also, know that the Glow community will NEVER stop talking about sexual preferences and orgasms. Take a gander in Community, and you’ll get a better sense of where your Glow sisters are #coming from ;)

Lookin’ fine on iOS9


Apple’s iOS9 launches today, and so do the next versions of Ruby and Glow!

One of the sweetest updates in iOS9 is HealthKit 2.0. It’s the HealthKit we love PLUS reproductive health features :)

Our apps are HealthKit’s BFFs. Your logs on Ruby and Glow will sync with your Health App, and vice versa, so that your reproductive health info is up-to-date everywhere, all the time. 

Also, you’ll be able to see fitness, nutrition, and sleep alongside your cycle info. Repro health doesn’t happen in a vacuum, and the new iOS9 integrations reflect that.


One last thing: Ruby’s now on Apple Watch. Smart wrists of the world will always know when period time is nigh :)


When Periods Are A Pain


Pain is a pain—and some women experience pain on a fairly regular basis. There is overwhelming evidence that, on average, women experience more pain than men do. Women report greater prevalence, frequency, and duration of clinical pain and pain-related distress than their male counterparts, on average. Always overachieving, aren’t we ladies?!

Unsurprisingly, women also deal with extra special doses of regular pain thanks to the menstrual cycle. But that pain drain does not affect all women equally.  Why is it that some ladies breeze through their cycles without any pain, while the rest of us curl up and binge watch Netflix, doubled over in agony during our periods? Well, there are a lot of factors at play.

First, cramps. An estimated 90% of women experience painful periods at some time in their lives, and  20% of women suffer from severe period pain every dang month.  The risk factors for cramps aren’t really within one’s control—cycle irregularity, early onset of puberty, family history, and being younger than 20 are all potential causes. Home treatments (our friends, the pain relievers) and medical treatments can sometimes remedy these symptoms. But not always. And Netflix often proves to be the only consolation.

But cramps aren’t the only type of period pain—how ‘bout them tender breasts? If you’ve ever had tender breasts during your period, hormone changes that occur throughout the cycle are the likely culprits. As estrogen levels rise in the first half of the cycle, the breasts ducts enlarge. This is great when wearing a push-up bra, but in general, pretty uncomfortable. Additional risk factors for tender breasts include family history, a high-fat diet, and too much caffeine. Since ⅔ of these are in your control, do yourself a favor and take some measures to protect the ta-tas :)

Life’s not fair, and some women are just more prone to pain in general.  There are a few reasons for this.  To begin with, pain perception depends on the brain, and brains vary from human to human because of differences in physiology, genetics, life experiences, and emotions. One person’s “ouch” could be another person’s “[insert four letter word here]!” simply due to biological variability.

Also, pain tolerance can be affected by a whole host of non-biological variables.  For example, in a recent study, a woman’s romantic relationship status seemed to affect whether or not she had differences in pain sensitivity throughout her cycle. In a population of 135 women, a correlation was seen between stages of the menstrual cycle and pain sensitivity for women in romantic relationships, but no such correlation was observed among women who were single.  The world is a strange place.

So what’s a girl to do to keep her pain in check? The best action you can take is to pay attention to your body and the timing and severity of the pain you experience, whether it be period pain, headaches, or the pain of seeing acne on yo’ face :) The new Ruby by Glow app helps you visualize pain and symptoms that you experience alongside your cycle, which could help you find patterns to your own pain tolerance.  Hop to it and start logging—before too long, you’ll have that pain pinned down.



We’ve all been there with those WTF questions about our bodies, sex, birth control, you name it. Wouldn’t it be great to have a one-stop-shop to answer all your Qs? The wait is over – today, we’re bringing you Ruby by Glow. It’s Glow’s newest app, and your new best friend.

Put simply, Ruby is the essential health and sex app that’s 100% focused on you. And it doesn’t just revolve around your period (because, duh, that’s only a few days out of the month). Ruby offers personalized suggestions for you to live your best life in every facet. We’re talking sex advice, health tracking, birth control tips and a fun, like-minded community. All in one app.

To further this we’ve also partnered with Bedsider – an online birth control support network operated by The National Campaign to Prevent Teen and Unplanned Pregnancy – to deliver the latest information about birth control and safe sex. Bedsider’s resources will be integrated throughout the app with a specific section of birth control types in the Me tab.

We think all women should be empowered with information about their own health, and that information should be smart, personalized and right at your fingertips. We can’t wait for you to check out the Ruby app, which you can download here.

Bed is better together with Bedsider

But our mission to empower women doesn’t stop there. As part of Ruby’s launch, we’ve partnered with Huru International, a nonprofit that provides menstrual hygiene supplies and sex-ed to young women in Kenya.

Did you know that in some parts of the world getting your period isn’t just a burden, but can actually prevent you from going to school or having a job… or even put you at risk for serious health issues and infections?  With a lack of funds and stigma around periods, many young women lack access to feminine hygiene products.

Some women who have to go without sanitary supplies end up using dangerous substitutes – like dirty rags or leaves – while others feel that they must stay home for the duration of their period. This means missing precious days of school and work.  These missed days add up very quickly and result in missed education, missed income, and missed opportunity.

Could you imagine not being able to leave your house for five or more days every month?  Missing out on school, your job, your friends, your community…all because of a normal and totally natural biological event?  It gives a whole new meaning to the concept of period problems.

Our friends at Huru International have found that distributing reusable menstrual pads and educating girls about their reproductive / sexual health and birth control allows over 90% of female students to stay in school during their periods. That is huge! Best of all, Huru Kits are environmentally friendly and locally produced, creating new jobs in the communities.

We’re so excited to support this mission and bring opportunity and education to even more women worldwide – and we want you to join us! Okay?

Here’s the plan: For every mention of Ruby’s hashtag #TalkRubyToMe on Twitter and Instagram, we will donate to Huru to give a young woman a day back, either at school or at work. We need you to help spread the word! Tweet it out, Insta, tell you friends, tell your mom – shout it from the rooftops. We want to give back 10,000 days to women in Kenya, and we need your help to make that happen.  

Keep girls in school. Period.
