The phenomenon of saliva crystallization and the fern sign on microscopy of a native smear: connection with estrogen levels and ovulation detection.
🔬 Native smear of female saliva. Crystallization in the form of “fern leaves”. 🌿 The fern sign indirectly indicates high estrogen levels, which rise during ovulation. 📈 This can be a useful indicator for determining the favorable time for conception. 🌸
