CycleBeads are available from Cycle Technologies under license from Georgetown University, Institute for Reproductive Health. As part of Georgetown University's School of Medicine, the Institute is working to advance the base of scientific knowledge on reproductive physiology
To use CycleBeads a woman simply moves a ring over the
series of color-coded beads that represent the days of her cycle. The color of the beads lets her know whether she is on a day when she is likely to be fertile or not. The one medical criterion for using CycleBeads to prevent pregnancy is that a woman should have cycles between 26 and 32 days long.
It is actually an old method, but is innovatively packaged as new.It is a modification of the Natural method. This method is to be used by women.
1.having regular cycles
2.Wish to avoid hormonal and other existing methods of contraception in popular use.
3.Co-operative partner.
The day a woman starts her period she puts the rubber ring on the red bead. Each day she moves the ring one bead, always in the direction of the arrow. When the ring is on the red bead or a dark bead, there is very low likelihood of pregnancy, so she can have intercourse on these days without getting pregnant. When the ring is on a white bead - Days 8 through 19 - there is a high likelihood of getting pregnant if a woman has unprotected intercourse
