“…The same considerations apply to the theory suggesting that large endometriomas may develop as a result of secondary invasion of luteal cysts by ovarian surface endometriotic cells 14 . In fact, according to the available evidence, ovulation occurs either equally on both sides 15 or more frequently on the right 16 but not the left side. If instead retrograde menstruation is the origin of endometriotic lesions 2,3,17 our findings should be considered taking into account anatomic factors that may influence the distribution and implantation of regurgitated endometrial cells 4,18,19 .…”

Objective To investigate whether asymmetry exists in the left-and right-handed distribution of Design Retrospective evaluation of a case series. Setting Tertiary care and referral academic centre for the study and treatment of endometriosis. Population A total of 1054 consecutive women undergoing first-line surgical treatment for Methods Data were collected on indication for the intervention, age at surgery, parity and disease Main outcome measure Frequency of left-and right-sided ovarian endometriomas. Results Histologically confirmed endometriotic ovarian cysts were present in 561 women, which were on the left side in 255 instances, on the right in 148, and bilateral in 158. In the patients with unilateral endometriomas, the observed proportion of left cysts (255/403, 63%; 95% confidence interval, 58Y0 to 68Yo) was significantly different from the expected proportion of 50% (x2,, 28.41, P

“…By adding 0.31 to 14.13 a value of 14.44 days is obtained which agrees closely with the geometric mean luteal phase length (14.3 days) calculated using the parameter intermenstrual pain (Vollman 1977). This suggests that intermenstrual pain may well be associated with actual event of ovulation ( H a m et al 1979;Marinho et al 1982).…”

Normal probability plots were used to assess the homogeneity of a population of 327 luteal phases from apparently ovulatory menstrual cycles. The length of the luteal phase was defined as the interval (in days) following but not including, the luteinizing hormone peak, up to and including the day before onset of menstruation. A small sub-set of the population consisted of cycles with abnormally short luteal phases but the majority of the data followed a normal frequency distribution which gave a mean (+ SD) for normal luteal phase length of 14.13 (k 1.41) days. It was estimated that all cycles with a luteal phase < 9 days were abnormal, and that 74%, 22% and 2% respectively of cycles with luteal phases of 10, 11 and 12 days were also abnormal. The total incidence of short luteal phases defined as above was 5.2%.

“…A chronological order of ovulations was then calculated which suggested that ovulation occurred in a turn-about manner. Other studies in the human (Marinho et al, 1982) and non-human primate (Dukelow, 1977;Hodgen, 1982) also implicate contralateral ovulation. In contrast, Werlin et al (1986) suggest that ipsilateral ovulations are the norm in women.…”

The processes that precisely control the selection of ovulatory follicles from a growing cohort are poorly understood. This reduction in follicle number occurs through several phases of selection, consequently we limit the use of the term 'selection' to the first major reduction of growing follicles, at the pre-to early antral stage. The final process of selection, achieving the appropriate ovulatory number, is referred to as 'dominance'. We discuss possible mechanisms that could bring about these reductions and highlight intra-ovarian involvement, particularly via follicle-follicle interactions. Analogies are drawn between local ovarian events and processes commonly reported in the determination of cell fate in developmental biology. Two facets of intra-follicular interactions are proposed: initially that follicle-follicle interactions mediate early selection processes at the preantral stage, and later that during antral development dominant follicles directly affect the fate of the subordinate cohort members.
