Intervention(s)
Participants will complete the study questionnaire pre-operatively. The study questionnaire will be available electronically via online platform ‘SurveyMonkey’ and in hard copy form if requested.
The participants' anogenital distance (AGD) will be measured after they are anaesthetised, in the lithotomy position, by two of the treating team. It will be measured using disposable paper ruler. Two measurements will be taken. The AGD AC is the distance from the anus to the anterior part of the clitoral hood. The AGD AF is the distance from the anus to the posterior fourcette.
If the patient is undergoing a laparoscopy, the treating clinicians will be asked to note whether or not endometriosis is present.
The AGD will be measured again at the conclusion of the procedure.

Primary Outcome(s)
Compare the AGD AF (as measured with a disposable paper ruler in the lithotomy position) of participants with histologically proven endometriosis diagnosed at the procedure (endometriosis positive laparoscopy), to those without endometriosis (endometriosis negative laparoscopy)[Measurements will be taken during surgery and analysed for the all participants at the conclusion of the study, 24 months after commencement of the study.]
Determine the mean AGD AC (anterior anogenital distance) for the studied population as measured with a disposable paper ruler in the lithotomy position.[Measurements will be taken during surgery and analysed for the all participants at the conclusion of the study, 24 months after commencement of the study.]
Determine the mean AGD AF (posterior anogenital distance) for the studied population.as measured with a disposable paper ruler in the lithotomy position.[Measurements will be taken during surgery and analysed for the all participants at the conclusion of the study, 24 months after commencement of the study.]
Secondary Outcome(s)
The determine the relationship, if any, between AGD measurements and participant BMI. [A participant questionnaire will be completed prior to surgery. Measurements will be taken during surgery. Data will analysed for the all participants at the conclusion of the study, 24 months after commencement of the study.]
To determine the relationship, if any, between AGD measurements and a previous diagnosis of PCOS, as reported by the participant[A participant questionnaire will be completed prior to surgery. Measurements will be taken during surgery. Data will analysed for the all participants at the conclusion of the study, 24 months after commencement of the study.]
To determine the relationship, if any, between AGD measurements and parity, as reported by the participant.[A participant questionnaire will be completed prior to surgery. Measurements will be taken during surgery. Data will analysed for the all participants at the conclusion of the study, 24 months after commencement of the study.]
