largest egg freezing ethnographic study to date: The two-year study comprised 150 women who had completed at least one cycle of non-medical egg freezing and volunteered to participate in the study. At the time of egg freezing, 85 percent of the women were single, and of these single women, 35 percent had experienced a breakup. Additionally, 26 percent of the married and partnered women in the study were in the midst of separations.

For a full discussion on male infertility and the plummeting sperm levels among men in Western countries, see Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Development, and Imperiling the Future of the Human Race by Shanna H. Swan, in which she writes, “…it’s that the chemicals in our environment and unhealthy lifestyle practices in our modern world are disrupting our hormonal balance, causing varying degrees of reproductive havoc that can foil fertility and lead to long-term health problems even after one has left the reproductive years.”

the fun really begins: Once past the obstacle of the cervix’s muscular contractions, sperm must then “choose” and swim up one of two fallopian tubes, while the egg only travels down one. Then, the egg can affect which sperm wins the race—the audition, really—with the chemicals it releases in the follicular fluid that surrounds the egg. The sperm that gets there first and is able to penetrate the egg shell—via the very complex biological process that has to occur—gets the starring role in conceiving a baby.

Fertilization happens when: The establishment of a pregnancy is a process: first fertilization, then implantation. Between one-third and one-half of all fertilized eggs never fully implant in a woman’s uterine lining. Also worth noting: The term “conception” isn’t actually a medical term, and it’s often mistakenly used synonymously with “fertilization,” when technically it’s equated with implantation.

they’d use a condom: Although, Will noted, there was something to be said for having to wait. As Weschler writes: “By choosing to postpone sex rather than using a barrier method during the fertile phase, people often feel they’re living in harmony with their fertility, rather than fighting it.” Weschler, Taking Charge of Your Fertility, 164.

an unintended pregnancy: One of the more alarming studies illustrating the unreliability of fertility-tracker apps was a case study in 2018, when thirty-seven women who relied on the European fertility app Natural Cycles as their contraception method reported unwanted pregnancies. Authorities in Sweden investigated the app, which is certified in Europe for birth control and approved for marketing as a contraceptive in the United States by the FDA. Natural Cycles has since further clarified the risk for users.

federal safeguards for patient privacy: It’s better in Europe, though. One reason I decided to use Clue’s app is that the company that developed it is based in Germany, where it’s subject to stricter regulations. The company follows the same EU restrictions for every person using the app, including those in the United States. Clue also makes it easy for users to understand how it shares users’ information—its privacy policy is light on jargon and broken down into readable chunks—and lets people opt out of having their data shared.
