American women are having only half as many babies as they did 50 years ago, but fertility technology is becoming a bigger and bigger business.

The big picture: The number of babies born per U.S. woman has dropped from 3.58 to 1.89 in the last half century. But women still want help getting pregnant — and answers about their health outside the doctor's office.

So dozens of companies are crowding a market projected to reach $30 billion in annual sales in five years, introducing tracking apps, wearable tech and at-home fertility tests.

  • Andreesen Horowitz recently invested in Glow, a company that raised $23 million. Glow makes apps that track menstruation, fertility and pregnancy.
  • Union Square Ventures put money in Clue, which makes a competing app and raised $29 million.
  • Sequoia led funding for Maven, a virtual women's health clinic.

Other innovators in fertility tech include Meet You, a Chinese fertility tracker app that doubles as a social network; Ava, a wearable device that tracks fertility through physiological metrics like body temperature and breathing rate; and Quanovate, a device that gives real-time feedback on a woman's fertility based on urine samples.

  • "There's potential for this area to really grow," says Ja Lee, an analyst at CB Insights. "You have half the population that wants this, but there are not consumer-friendly solutions that are easy to understand."

Between the lines: Many younger women are using these new apps not to pursue pregnancies, but to avoid them, Lee says. "Even if they may not want to have kids ... it gives women info about their general health."

Australia joins U.S. in diplomatic boycott of Beijing Winter Olympics

Australia is joining the U.S. in a diplomatic boycott of the 2022 Beijing Winter Olympic Games in protest of human rights abuses committed by China's government, Prime Minister Scott Morrison said Wednesday.

Driving the news: After the Biden administration's announcement that U.S. officials won't attend the Games due to the ongoing genocide of Uighurs and other Muslim minorities in the Xinjiang region of China, Morrison said at a Sydney briefing that Australia would follow suit as "it's the right thing to do."

Progressives to file resolution to strip Boebert's committee seats

House progressives are planning to introduce a resolution on Wednesday to strip Rep. Lauren Boebert (R-Colo.) of her committee assignments, according to a Democratic aide familiar with the matter.

Why it matters: The move, which was first reported by the Washington Post, comes as progressives — anxious to see the right-wing firebrand face retribution for her recent comments — have grown frustrated by Democratic leadership's inaction on the issue.

Roger Stone won't cooperate with Jan. 6 panel

Longtime Trump confidante Roger Stone won't cooperate with the House select committee investigating the Jan. 6 Capitol riot and will invoke the Fifth Amendment right not to testify, his attorney said Tuesday evening.

Why it matters: The announcement, first reported by ABC News, came hours after former White House chief of staff Mark Meadows said he wouldn't cooperate with the probe.
