Testosterone, popularly heralded as the male sex hormone, has a vital part to play in the female body too, contributing to much more than just male reproductive tissues. As it turns out, those assigned female at birth also boast a certain level of it, experiencing wavering amounts throughout their lifetime. But the catch is, even medical professionals haven't nailed down a precise "normal" testosterone level in women, so navigating the hormonal highs and lows might feel like an episode of "American Ninja Warrior."

The reason testosterone matters, is that it clocks in for more than just a cameo role in your health. Its presence or absence impacts red blood cell production, hormone regulation, and mood balance. Symptoms of a testosterone deficit in people assigned female at birth can range from feeling sluggish and weak, to having irregular periods. Yet, some may twirl through life with low testosterone without so much as a hiccup.

Testosterone doesn't decline at a slope, but rather takes a downhill ski route. The jumps and bends are due to natural aging or chronic health conditions, one the main culprits being menopause as the ovaries start losing their mojo. Scenarios such as complications with the ovaries, adrenal glands or pituitary gland may also spur a decline.

If you're nodding along to the symptoms listed, medical professionals can help diagnose low testosterone levels with a simple blood test. But, keep in mind that these symptoms could also be masquerading as chronic stress or depression. The art of hormonal balance becomes all the more tricky since testosterone levels can fluctuate throughout the month in pre-menopausal individuals. Doctors will often recommend a specific time to take the test for accurate results.

While science is still figuring out the testosterone norm, treatment options are anything but scarce. The FDA has given the thumbs up to a few treatments designed to boost your energy levels and rev up your sex drive. But fair warning, these come with the side effects any hormone supplement might bring.

To sum it up, testosterone isn't just the star quarterback in the men's team; it's a key player in the women's squad too. But if you've noticed fatigue, muscle weakness, irregular periods, or a dwindling sex drive, it might be time to chat with your healthcare provider. Remember, the ultimate goal is to find the hormonal sweet spot where your mind and body feel at their best, and sometimes, that might require an extra dose of testosterone.
