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."

Wall Street fears meltdown over election and Supreme Court

The death of Justice Ruth Bader Ginsburg and President Trump's vow to name her replacement to the Supreme Court before November's election are amplifying Wall Street's worries about major volatility and market losses ahead of and even after the election.

The big picture: The 2020 election is the most expensive event risk on record, per Bloomberg — with insurance bets on implied volatility six times their normal level, according to JPMorgan analysts. And it could take days or even weeks to count the record number of mail-in ballots and declare a winner.

Election clues county by county

Ipsos and the University of Virginia's Center for Politics are out with an interactive U.S. map that goes down to the county level to track changes in public sentiment that could decide the presidential election.

How it works: The 2020 Political Atlas tracks President Trump's approval ratings, interest around the coronavirus, what's dominating social media and other measures, with polling updated daily — enhancing UVA's "Crystal Ball."
