U.S. regulators on Friday approved a birth control gel that works in a new way to prevent pregnancy.
Phexxi comes in an applicator that women insert before sex. The gel made by San Diego-based Evofem Biosciences contains lactic acid, citric acid and potassium bitartrate, all of which are common food additives.
The new gel has some similarities to spermicides, which block the entrance to the cervix and slow sperm down. But Phexxi works differently.
The vagina’s pH — a measure of acidity — is typically in the range of 3.5 to 4.5, the level needed to maintain healthy bacteria. Sperm raise that to a more hospitable level of 7 to 8. Phexxi keeps it in the usual acidic range, killing the sperm.
Unlike some other contraceptives, it only needs to be used shortly before sex and it doesn’t contain hormones, which can cause side effects some women can’t tolerate.
The company said Phexxi — pronounced FECK’-see — will have a list price of $250 to $275 for a box of 12 without insurance.
In a study of 1,400 women aged 18 to 35, Phexxi was about 86% effective on average over seven menstrual cycles and a total of more than 34,000 acts of intercourse. That’s a bit better than condoms, spermicides and other “on-demand” contraceptives, but less effective than long-term methods such as IUDs and implants.
Phexxi’s side effects were minimal — mostly irritation and burning, which declined sharply after repeated use.
“This would be a pretty big deal,” if Phexxi’s effectiveness and safety in real-world use match results of the patient tests, said Dr. Luu Ireland, a University of Massachusetts contraception specialist. The more nonhormonal contraceptives available to women, the better, she added.
Phexxi appears to be a “terrific backup” method if used with a condom, said Dr. Lauren Streicher, medical director of the Northwestern Medicine Center for Sexual Medicine and Menopause in Chicago.
“If you have a guy who refuses to use a condom, this is a great option,” she added.
The Food and Drug Administration approved Phexxi only as a contraceptive, but Evofem said its testing indicates the gel also reduces the risk of infection by gonorrhea and chlamydia. U.S. cases of both infections have been rising for several years.
The company plans to start a large patient study by year's end, then submit results to the agency for approval as a second product, for preventing those infections.
Evofem could market it under a different name, and likely could tout Phexxi as both birth control and a way of helping to help prevent at least some sexually transmitted diseases.
“If that pans out, that would be quite revolutionary,” said Ireland.

7 Energy Stocks to Buy On This Historical Dip
It may seem hard to believe, but the current chaos in the energy sector, and oil stocks, in particular, will pass. The novel coronavirus that has birthed a global pandemic is being compared to the Spanish Flu of 1918.
Of course, when you have once in a century event, it’s difficult to look back in history and make an apples-to-apples comparison to our current situation. This isn’t to minimize our current situation. It’s simply to say that the market is forward-looking, but it’s also emotional. And it also hates uncertainty.
In a typical economic downturn, demand decreases, and investors are advised to “buy the dip.” But in the current environment, demand has been destroyed. Millions of Americans are being asked, and in some cases ordered, to stay home. And this simply means that oil demand is down. And investors are looking at prices that are, in some cases, at all-time lows.
The trading app Robinhood is frequented by millennial investors. And according to the latest information, many investors are trying to buy the dip on old guard oil stocks. That may be a mistake.
But the energy sector is about more than just oil stocks. There are several companies that are holding their own in the current environment. And that means when the economy opens up, these companies will be well-positioned for further growth.
Currently, the volatility and uncertainty surrounding energy stocks make them a poor choice for growth investors. However, many of these companies in this presentation offer a secure dividend that, along with the potential for capital appreciation, can make them a solid play for income investors.
