“Half the World Has a Clitoris. Why Don’t Doctors Study It?” That was the attention-grabbing headline of a story published by The New York Times last October that quickly made its way across many women’s group-chat threads. “This!” one friend texted me with a link. Indeed the story cracked open a topic that has been woefully overlooked, not just culturally but also medically. That the clitoris is connected to women’s pleasure is at the heart of the issue. “The full anatomy of the clitoris wasn’t published until 2005 by Dr. Helen O’Connell, if you can believe that,” says Amy Killen, MD, a regenerative- and sexual-medicine practitioner. “If we’ve only understood the shape of the clitoris for 18 years, it’s not a surprise that we’re behind in understanding female sexual pleasure compared to male pleasure.”
Look at a diagram comparing the anatomy of the clitoris to that of the penis (women’s health start-up Alloy Health handily offers one on their website) and you’ll be struck by the similarities. “When doctors showed us that chart, I was like, Oh, my God, I had no idea how large the clitoris was—it really shouldn’t be that hard to find,” quips Anne Fulenwider, cofounder, along with Monica Molenaar, of Alloy Health. Medical textbooks are often missing anatomical drawings of this clitoral anatomy and aroused vaginas, leading to a major knowledge gap, says Carolyn Wheeler, cofounder of sexual-wellness brand Vella. “The Western medical establishment—specifically how medicine is taught and practiced—is still broadly illiterate when it comes to female sexual anatomy and physiology, as conceptually distinct from our ability to reproduce,” says Wheeler.
That physiology can change dramatically with age and the menopause transition and have a ripple effect on sex drive, libido, and arousal. First there are diminishing hormones, particularly estrogen and testosterone. “Testosterone is the main hormone responsible for a healthy sex drive and libido,” says Monica Grover, MD, an ob-gyn and chief medical officer for sexual-health spa VSPOT, adding that a decrease means less signaling to the genital system to increase sensitivity and response. Estrogen also plays a role. “The decline in estrogen impacts sexual behavior in women due to its connection to genital arousal,” says Leah Millheiser, MD, an ob-gyn and chief medical officer for menopause telemedicine company Evernow. Less blood flow means less vaginal lubrication, difficulty with or an inability to achieve orgasm, and decreased sensation in the vulva during sexual activity. Grover points to vaginal atrophy, which can cause pain and dryness during intercourse, as another significant physical roadblock for libido. She says low libido can be a side effect of necessary medications like antidepressants, anxiolytics, antipsychotics, antacids, and even ones for blood pressure, not to mention a result of anxiety and stress, concerns about body image, and discord in your relationship. Statistics show that about 40% of women report some degree of sexual dysfunction, though it’s important to note the word report there, as it’s something that most women aren’t regularly doing with their doctors. “Most doctors don’t ask you about how pleasurable or good your sex life is because they don’t want to have the conversation, and also patients don’t want to bring it up,” says Molenaar. Killen points to a 2012 study of ob-gyns that found that while 65% of doctors ask patients if they’re having sex, only around 14% follow up with whether it’s pleasurable.
And for those women with a healthy libido, while they have desire, they may still struggle with actual arousal or an arousal strong enough to reach orgasm. “The female sexual-response cycle generally starts at desire, which is psychological. Desire leads to arousal, which is physiological, and arousal leads to orgasm,” says Wheeler. Just as arousal presents itself as an erection for men, the same is true for women; it’s just more difficult to see and feel an erection in the clitoris. Oral Viagra (known generically as sildenafil), which has been approved for use in men since 1998, is a vasodilator that increases blood flow to the penis leading to an erection. “There is data showing that Viagra can increase blood flow to the genitalia in women, which can increase sensitivity and arousal,” says Millheiser, adding that it has been prescribed for years off-label, not for low libido but for the treatment of genital-arousal disorder or orgasmic disorder. It’s a solution for women that has been hiding in plain sight, says Molenaar. “The only reason it hasn’t been available for women is that nobody cared or prioritized our sexual pleasure,” she says.
