Testosterone in Women: How It Changes Throughout Your Cycle

Testosterone in women peaks around ovulation, influencing libido, energy, and confidence. In PCOS, excess androgens disrupt the cycle. Here's how testosterone

Testosterone isn't a 'male' hormone — it's a crucial part of female physiology that most cycle education completely ignores. The conventional picture of female hormones is estrogen and progesterone, with testosterone as an afterthought. This is incomplete. What Testosterone Does in the Female Cycle Women produce testosterone primarily in the theca cells of the ovaries and in the adrenal glands. Normal female testosterone levels are roughly 15–70 ng/dL — about one tenth of typical male levels — but even at these concentrations, testosterone has meaningful physiological effects. The ovulatory peak Testosterone and DHEA (its precursor) peak around ovulation alongside the LH surge. This timing isn't coincidental. From an evolutionary perspective, the peak in libido, sociability, and confidence that many people notice around ovulation is partly testosterone mediated. Studies have shown increased facial attractiveness ratings, higher voice pitch, and more approach behavior around ovulation — all consistent with a testosterone and estrogen combined effect at mid cycle. If you track your energy and libido by cycle day, you'll often see a distinct peak in days 11–14 (for a 28 day cycle). Th
