Semen does not enter through the uterus, just sperm that can swim up there. This eliminates bad or defective sperm that cannot make it and therefore is good because it is natures way of cutting the risk for bad sperm to fertilize an egg.
If you’re so sure that they absolutely “cannot make it,” then how can there be any “risk” of them fertilizing an egg?

Either there *is *a chance that they could be part of God’s plan for the conception of a new human life… or there
isn’t. You can’t have it both ways.
The fact is, they *can *make it. In other words, if the couple were trying to avoid pregnancy – but they made a mistake in their charting, and the woman happened to be fertile at the time of intercourse – following the SFI would, in itself, significantly reduce their chances of pregnancy. This information can be found right there in the Creighton handbook (5th ed., p. 58). Under the general rules, it says that the SFI should be followed “within one hour” of intercourse. Later on the same page, though, it mentions that “during the time of fertility, the couple should wait 30 minutes before employing the instruction. This assures that the sperm have an adequate opportunity to migrate through the cervical canal to the fallopian tubes where conception can occur.” It seems as if – at the very least – they should be telling *all *couples to wait 30 minutes. Otherwise, the woman will be deliberately engaging in unnecessary behavior that has a contraceptive side effect.
(I say “unnecessary,” because the basic reason for following this procedure is to avoid an extra day or two of abstinence. Other forms of the Ovulation Method – e.g., Billings or FOAF – don’t teach the SFI; they teach the “alternate days” rule instead. Even with Creighton, couples have the option of just waiting an extra day or two, instead of doing the SFI.)
Of course, the woman could say that she doesn’t “intend” this potentially contraceptive side effect; she’s just doing the procedure to help with the charting. But, if (like most NFP users) her reason for charting is to avoid getting pregnant, that argument rings rather hollow. So, although I’m not in a position to judge whether or not the procedure is “objectively disordered,” it does seem problematic to me.
Besides which… well… the procedure itself is just
weird. Not what I’d call a “natural” way to end each and every romantic evening… KWIM? :whacky:
Finally, my third objection to the SFI is that it seems to predispose many people to graphic discussions of their bodily fluids and marital activities on public internet forums.

(For anyone who thinks this thread is icky, rest assured that it can get a lot worse.

) I’m inclined to suspect that this has something to do with the overall way that the Creighton method is often taught. Even the introductory slide show we went to – which was open to the general public, male and female, Catholic and non-Catholic – was presented in extremely graphic and clinical detail, with no sense of modesty or decorum whatsoever. I mean, sure, our reproductive system is God’s marvelous handiwork… but **private **parts are
private, folks! Let’s save the up-close photos and in-depth analysis of different classifications of bodily fluids for the **private **consultation!
(For the record, I have no problem with discussing these topics, as long as the language is carefully suited to the context. My husband and I have given talks on marital sexuality and NFP at our parish… so I know that it’s possible to get the message across, while still being discreet.
