We get a lot of emails from husbands and wives who are distressed by the wife’s low interest in sex. Libido is affected by a whole host of factors — relationship, communication, family situation, stress, time management, hormones, and more — so medication shouldn’t be your first resort. But while you’re working on all those other areas in your marriage, it’s probably worth your time to talk to the wife’s doctor about any health problems that may be contributing to her disinterest or dissatisfaction with sex. This can be an embarrassing topic to bring up, but your sex life is worth an awkward conversation!

Along with the other tools available to your marriage, it appears that the drug flibanserin is effective at improving female libido.

Flibanserin is used for hypoactive sexual desire disorder among women. Those receiving flibanserin report a 0.5 increase compared to placebo in the number of times they had “satisfying sexual events”. In those on flibanserin it rose from 2.8 to 4.5 times a month while women receiving placebo reported also an increase of “satisfying sexual events” from 2.7 to 3.7 times a month. The onset of the flibanserin effect was seen from the first timepoint measured after 4 weeks of treatment and maintained throughout the treatment period.

Let me translate:

  • Baseline low libido women: 2.7 satisfying sexual events per month
  • Baseline low libido women taking placebo (sugar pill with no medical effect): 3.7 satisfying sexual events per month
  • Baseline low libido women taking flibanserin: 4.5 satisfying sexual events per month

As is often the case, placebos alone show significant improvement over the baseline. This means that you can do almost anything to improve your sex life as long as you believe it will work! The human mind is a powerful thing.

However, the results also indicate that flibanserin is significantly better than a placebo, so it’s worth asking your doctor if it’s a good option for you.

Here’s a fascinating study about using light therapy to increase the libido of men with low sex drives. Don’t worry, it’s not some hippy thing!

Exposure to bright light – similar to daylight – boosts levels of the male hormone testosterone and can triple sexual satisfaction, the research found.

“Before treatment, both groups averaged a sexual satisfaction score of around two out of 10, but after treatment the group exposed to the bright light was scoring sexual satisfaction scores of around 6.3 – a more than three-fold increase on the scale we used. In contrast, the control group only showed an average score of around 2.7 after treatment.”

While average blood levels of testosterone in the “control” group remained at around 2.3 nanograms per millilitre (ng/ml) before and after the study, those of the men receiving active light treatment rose from 2.1 ng/ml to 3.6 ng/ml.

“The increased levels of testosterone explain the greater reported sexual satisfaction,” said Prof Fagiolini. “In the northern hemisphere, the body’s testosterone production naturally declines from November through April, and then rises steadily through the spring and summer with a peak in October. You see the effect of this in reproductive rates, with the month of June showing the highest rate of conception. The use of the light box really mimics what nature does.”

The article doesn’t mention it, but testosterone is also essential for women’s libido. (Though, of course, at lower levels of the hormone than men require.)

And best of all, you don’t need a fancy “light box”! Just go outside and bare some skin to that giant ball of fire in the sky that God helpfully provided — for free! The study quoted above indicates that as little as 30 minutes per day in the sun will have an effect, so go get some exercise.
