Finally, some data to back up natural family planning. It has to be followed correctly for it to work.
"Science Daily — Researchers have found that a method of natural family planning that uses two indicators to identify the fertile phase in a woman's menstrual cycle is as effective as the contraceptive pill for avoiding unplanned pregnancies if used correctly, according to a report published online in Europe's leading reproductive medicine journal Human Reproduction today (21 February)."
"The symptothermal method (STM) is a form of natural family planning (NFP) that enables couples to identify accurately the time of the woman's fertile phase by measuring her temperature and observing cervical secretions."
Here's their findings: "Of the 900 women, 322 used only STM and 509 women used STM with occasional barriers during the fertile time. Sixty-nine women did not document their sexual behaviour. Out of the women who documented their sexual behaviour and abstained from sex during their fertile period ("perfect use") the unintended pregnancy rate was 0.4 per 100 women and 13 cycles , and 0.6 for women who used STM plus a barrier if they had sex during their fertile period. For cycles in which couples had unprotected sex during the fertile phase, the pregnancy rates rose to 7.5 per 100 women and 13 cycles. The drop-out rate from using STM for reasons such as dissatisfaction or difficulties with the method was 9.2 per 100 women and 13 cycles, and compared well with the drop-out rates from other methods of family planning, which can be as high as 30%, although direct comparisons are difficult due to methodological problems. "This demonstrates a fairly good acceptability for this particular FAB method," said Prof Frank-Herrmann."
For those who cannot tolerate the pill, there are now other documented options that work just as well, IF you are willing to master it. :-)
