We studied the frequency of cervicovaginal bacteria in 47 pregnant women (16-41 weeks of gestational age), in 47 infertile patients and in 4 with gynecological diseases (not infections). When we compared the frequency of bacteria between pregnant and infertile women, we found that the biggest difference was with U. urealyticum. In fact the frequency of this germ was 61% in the total population studied, in pregnant women was of 72% which is statistically higher than the frequency in infertile women which was of 47% (p < 0.025). We think that the reason for the higher frequency of this germ is a consequence of the effect of estrogens that favors the proliferation of this of germ. In the case of M. hominis the frequency in pregnant women was of 13% and in infertile women was of 21% which was not statistically different. Within the group of infertile patients, those that had tubal damage had a higher frequency of germs that the patients that did not have damage, moreover M. Hominis was not detected in the infertile patients without tubal damage and in patients with tubal damage its frequency was of 25%.
我们研究了47名孕妇（孕龄16 - 41周）、47名不孕患者以及4名患有妇科疾病（非感染性）患者的宫颈阴道细菌频率。当我们比较孕妇和不孕女性之间的细菌频率时，发现最大的差异在于解脲脲原体。实际上，在所研究的总人群中，这种病菌的频率为61%，在孕妇中为72%，这在统计学上高于不孕女性中的频率（47%，p < 0.025）。我们认为这种病菌频率较高的原因是雌激素作用的结果，雌激素有利于这种病菌的增殖。对于人型支原体，孕妇中的频率为13%，不孕女性中的频率为21%，差异无统计学意义。在不孕患者组中，有输卵管损伤的患者病菌频率高于无损伤的患者，此外，在无输卵管损伤的不孕患者中未检测到人型支原体，而在有输卵管损伤的患者中其频率为25%。
