Countdown, by Shanna Swan, https://www.shannaswan.com/countdown is well-written in a manner that allows people without advanced degrees in biochemistry to understand what is happening in Western countries to both male and female fertility.
In short, chemical exposures, particularly at certain stages of pregnancy, are resulting in low sperm counts for men and premature ovarian aging for women. Sperm counts have decreased more than 50% over the past 40 years. In the long run, this has consequences for the human race.
In the short run, as in right now, for my younger readers, especially those planning families, it is important to start figuring out if you or your spouse is one of the people whom these exposures have already affected.
Dr. Swan has many YouTube videos that you can listen to while multitasking as well.
