During a 30-month period 229 couples were evaluated for infertility at the Naval Regional Medical Center, Oakland. Laparoscopy was used in all cases of otherwise unexplained infertility. The resulting laparoscopic examination of the female partner of 24 such couples demonstrated abnormal findings in 18 (75%). Of these 18 subjects, unsuspected endometriosis was found in 11 (46%) and peritubal adhesions in 7 (29%). Of the 229 couples evaluated, only 8 (3.5%) failed to show some etiologic factor associated with infertility. Thus, the previously reported 10 to 20% incidence of unexplained infertility is too high an estimate in view of the additional information made available through pelvic endoscopy.
在30个月的时间里，奥克兰海军地区医疗中心对229对夫妇进行了不孕症评估。所有原因不明的不孕症病例均采用腹腔镜检查。对其中24对夫妇的女性伴侣进行腹腔镜检查，结果显示18例（75%）有异常发现。在这18名受试者中，11例（46%）发现了未被怀疑的子宫内膜异位症，7例（29%）发现了输卵管周围粘连。在接受评估的229对夫妇中，只有8对（3.5%）未显示出与不孕症相关的病因。因此，鉴于盆腔内窥镜检查提供的更多信息，之前报道的10%至20%原因不明的不孕症发生率估计过高。
