Abnormal Uterine Contractility in Nonpregnant Women

The effect of the hormonal milieu of pregnancy on deep infiltrating endometriosis: serial ultrasound assessment of changes in size and pattern of deep endometriotic lesions

“…Some evidence suggests that early pregnancy may be prophylactic against the development of endometriosis and could actually cause regression of established lesions. The mechanisms postulated include production of anovulation and amenorrhea, decidual change and eventual necrosis induced within the lesions [21].…”

Long-term follow-up after laparoscopic treatment for endometriosis: multivariate analysis of predictive factors for recurrence of endometriotic lesions and pain

“…The mechanisms postulated include production of anovulation and amenorrhea, decidual change and eventual necrosis induced within the lesions. Moreover, vaginal parturition enlarges the internal ostium of the uterine cervix and might decrease recurrences by reducing tubal transportation of endometrial debris [22].…”

Tubal transport of spermatozoa does not appear to be dependent on normal cilia function

“…Although motility of spermatozoa seems to be of primary importance for fertilization, the contribution of ciliary activity and uterine peristalsis to sperm transport are still under debate (1,3,(7)(8)(9). The immotile ciliae syndrome (Kartagener's syndrome) may represent a model to address this question in the human female.…”
