The only information I was able to secure is the abstract of the article, and from it, the conclusion says that that while there is a link between chemical contraceptives and a decreased sex drive. They concludes, however that more evidence is needed for an accurate correlation to be seen.
Let me just say that I am not surprised at all. I have read hundreds of testimonies from women and men who attest that the use of contraceptives mysteriously changed their sex lives. It is one reason why women do not like to take the pill. So, if the pill is causing such trauma and stress in the lives of women, why is it promoted as the be-all, end-all for worry-free sexual relations?
Our culture is obsessed with sex, and Pope John Paul II said once that our culture is afraid of sex. We are afraid of the reality of babies and commitment, so we have allowed our selves to be spoon-fed the rhetoric of the contraception movement.
Getting back to the harms that contraception brings, let's address two things.
First of all, chemical contraceptives work primarily in suppressing ovulation. As a natural part of biology, however, a woman naturally will feel a stronger urge to have conjugal relations during when she is ovulating, for this is her fertile time. It is only during those 3-7 days that pregnancy can be achieved. If a woman is not ovulating, it is because her body is not producing the proper chemicals for ovulation. When using chemical contraceptives, the body's natural hormones are suppressed and there is a chemical imbalance. Because this chemical imbalance is purposefully induced, there is no wonder that there is a decreased desire to have sex.
Secondly, if a woman is suffering from a sexual dysfunction, there is no reason to believe that this dysfunction would not permeate ever aspect of her marital life. This will result in frustration of their conjugal life both in fertile and non-fertile times. Because of the use of hormonal contraceptives, men are equipped with the means to abuse women. On the other hand, if a couple is using Natural Family Planning, the couple must carefully chart the precise times that the woman is ovulating and work with that naturally bodily element.
In his 1960 book, Love and Responsibility, Karol Wojtyla (who later became Pope John Paul II) wrote of the need for men to work with the natural biology of a woman's fertility cycle.
Male continence must therefore adapt itself to the indications which the woman's organism provides… The marital relationship demands on his part tenderness, and understanding for the feelings of the woman. In this sense responsibility for planned motherhood rests mainly on the man, for only continence on his part makes it possible to capture the correct biological rhythm in marriage. (Ignatius Press edition- 1993, p. 283-284)
So, the conclusion is that it is quite irresponsible for physicians, social workers, educators, clergy, etc to be promoting a drug in the name of liberation of women which actually brings her more harm and increases her chances of being abused by her intimate partner (hopefully, that man is her husband). It is inconsistent with the message of the feminists that men are able abuse women more by the very ideals the feminists are promoting.
