Here's How Birth Control Can Affect Your Biomarkers

By Ashley Reaver, MS, RD, CSSD Jul 20, 2017

We're often asked if hormonal contraceptives can affect female biomarkers. The answer? Yes. It makes sense then, that women begin to wonder how they are affected, and to what extent.

Like any other medication, hormonal contraceptives (pills, patches, rings, IUDs, implants, and injections) interfere with the normal functioning of the body. Naturally, there can be some unintended residual effects. Therefore, some out-of-range biomarkers may be attributed to your contraceptive use, while others may be a combination of factors. It's important to note that throughout this blog post, we will refer to all hormonal contraceptives (pills, patches, rings, IUDs, implants, and injections), as OC – aka oral contraceptives. This may seem a misnomer, but in the current scientific literature, "OC" is used to characterize all hormonal contraceptives, unless indicated otherwise. We hope this post will help you better understand how your OC could be affecting some of your biomarker levels.

The Science Behind Testosterone Biomarkers

By Ray Nguyen Feb 26, 2014

Testosterone is a steroid hormone that is essential for muscle development and strength, bone health, sexual function, overall energy, and athletic performance. Although both men and women produce testosterone, women normally have very little of this hormone - a fraction of the amount that men typically have. However, having too much or too little testosterone can cause problems. Excess testosterone decreases the levels of HDL (good) cholesterol, affects heart health, and impairs sexual and reproductive function. In contrast, low testosterone can make you feel tired, uninterested in sex, and less competitive, as well as diminishing your athletic performance. Possible causes of low testosterone include overtraining and low levels of zinc and magnesium.
