The OVU-TEC™ allows a woman to discover exactly when her
preovulatory and ovulatory period begins. It allows a woman to chart and be more aware of her cycle as an aid in natural family planning.
There are other tools to help in family planning but none is as safe, reliable, convenient and inexpensive as the OVU-TEC™. This product is completely reusable. There is no need to purchase additional supplies, you just clean the slide.
