An Aside:

No 'safe' time to avoid pregnancy . . . 'Flabbergasted' scientists find they've been all wrong on ovulation

I found this a fascinating article.
In the meantime, "it tells us why some women don't get along well with oral contraceptives." Most birth control pills are based on a 21-day treatment cycle, where women take active hormones, followed by seven days of placebo or "dummy" pills, which trigger menstruation.

Apparently, birth control pills rely on old-style 'rythmn' assumptions which is something I never knew.

There's an off-the-cuff snide remark about natural family planning but, based on the little I know (which given my non-marital state is next to nothing), it seems that this might be a further argument in favor of NFP. As far as I know, current NFP methods are based on measurable bodily changes which would show up when ovulation occurs and would be unaffected by the new data.

The statistics put out by the Couple to Couple League show a 97-99% effective rate.
