据阿伯丁大学Philip Hannaford教授领导的the Royal College of GPs Oral Contraception Study研究小组在英国医学期刊(British Medical Journal)上发表的最新研究成果:经过40年的研究,统计了超过46,000个妇女进行对比试验,发现每100,000服用避孕药的妇女中,比其他避孕方式的平均少死亡52人
[80],服用避孕药的妇女预期死亡率比不服用者低12%[67]。这个研究基于旧式的避孕药,因此新式(激素含量更低)的避孕药可能没有这个“功效”。

^ 20.020.120.220.3Pincus G, Bialy G. Drugs Used in Control of Reproduction. Adv Pharmacol. 1964, 3: 285–313. PMID 14232795. doi:10.1016/S1054-3589(08)61115-1. The original observation of Makepeace et al. (1937) that progesterone inhibited ovulation in the rabbit was substantiated by Pincus and Chang (1953). In women, 300 mg of progesterone per day taken orally resulted in ovulation inhibition in 80% of cases (Pincus, 1956). The high dosage and frequent incidence of breakthrough bleeding limited the practical application of the method. Subsequently, the utilization of potent 19-norsteroids, which could be given orally, opened the field to practical oral contraception.

(1957) employing the same regime of progesterone administration also observed suppression of ovulation in a proportion of the cases taken to laparotomy. Although sexual intercourse was practised freely by the subjects of our experiments and those of Ishikawa el al., no pregnancies occurred. Since ovulation presumably took place in a proportion of cycles, the lack of any pregnancies may be due to chance, but Ishikawa et al. (1957) have presented data indicating that in women receiving oral progesterone the cervical mucus becomes impenetrable to sperm.

At the Fifth International Conference on Planned Parenthood in Tokyo, Pincus (1955) reported an ovulation inhibition by progesterone or norethynodrel1 taken orally by women. This report indicated the beginning of a new era in the history of contraception. [...] That the cervical mucus might be one of the principal sites of action was suggested by the first studies of Pincus (1956, 1959) and of Ishikawa et al. (1957). These investigators found that no pregnancies occurred in women treated orally with large doses of progesterone, though ovulation was inhibited only in some 70% of the cases studied. [...] The mechanism of protection in this method—and probably in that of Pincus (1956) and of Ishikawa et al. (1957)—must involve an effect on the cervical mucus and/or endometrium and Fallopian tubes.

[...] Still, neither of the two researchers was completely satisfied with the results. Progesterone tended to cause "premature menses," or breakthrough bleeding, in approximately 20 percent of the cycles, an occurrence that disturbed the patients and worried Rock.17 In addition, Pincus was concerned about the failure to inhibit ovulation in all the cases. Only large doses of orally administered progesterone could insure the suppression of ovulation, and these doses were expensive. The mass use of this regimen as a birth control method was thus seriously imperiled.18 [...]
