Perimenopause is the hormonal transition leading up to menopause, often starting in your 40s. Learn about common symptoms, natural support options, and body-identical hormone therapies—from dietary changes and phytoestrogens to over-the-counter creams and prescription treatments—in this simple, evidence-informed guide by Girl Power Science founder Konika Ray Wong, M.Ed.

Did you know that perimenopause and puberty are the two most intense periods of estrogen fluctuation in a woman's life? Some scientists describe perimenopause as "puberty in reverse." Progesterone starts to decline and estrogen fluctuates more intensely.

Signs of the onset of puberty and perimenopause are similar including body aches, irritability, sensitivity, and mood swings. During puberty, these signs show up before physical signs such as breast buds. Clues that perimenopause is arriving appear before changes in your menstrual cycle.

Navigating modern puberty is dramatically different. Puberty now starts earlier, lasts longer, and intertwines with technology in unimaginable ways. Luckily, there are new resources that we didn’t have when we grew up.

Summer is the perfect time to grow girl power by developing a sense of agency. From the farmer’s market to the nearest hiking trail, check out ideas for creating opportunities for more autonomy in your child’s life.

Whether it's your daughter's first period or not, being prepared is a game changer.

To empower girls to feel confident about this big change, it’s important to start talking about periods early.

Neuroplasticity during puberty is powerful. Starting as early as age eight and ending around age eighteen, your child’s brain goes through a huge remodel. The prefrontal cortex which controls decision making forges connections with the boss of our emotions called the amygdala. There are actions we can take to help empower our children to be the architects in charge during the renovation.
