Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be involved in this study for 2 menstrual cycles only,comprising a control cycle and an intervention cycle. Arm 1 of this study is the intervention cycle during which participants will be randomised to have either (group a) intercourse at least once using condoms, (group b)intercourse at least once without condoms, or (group c) abstain from sexual intercourse. Intercourse will be timed to occur (group a and b) or not (group c) at time of Lutenising Hormone (LH) surge in menstrual cycle and endometrial biopsy will collected 10 - 12 hours after intercourse. During the cycle up to the time of randomisation and group allocation they will be required to abstain from intercourse or use a condom, to prevent contamination of the endometrium with seminal fluid. Arm 2 of the study is the control cycle during which an endometrial biopsy will be collected at time of LH surge, with out seminal fluid present. To aviod contamination of the endometrium with seminal fluid participants will be be able to chose to abstain from sexual intercourse or wear condoms for the duration of the cycle. There is no requirement for a washout period between cycles but there can be no longer than 3 months between intervention and control cycle. Total duration of participation in the study is 8 weeks (2 x 4week cycles)

Lifestyle
Comparator / control treatment
All participants will have a control cycle in which they will abstain from intercourse or use a condom prior to having an endometrial biopsy collected at time of LH (Lutenising Hormone) surge
Control group
Active

Outcomes
Primary outcome [1] 257445 0
determine a similar but distinct inflammatory cytokine response in cervical cells and endometrium after sexual intercourse for histochemical analysis. A sample will also be placed into RNAlater for extraction of ribonucleic acid (RNA) for quantative reverse transcription (qRT) polymerase chain reaction (PCR) and Affymetrix microarray analysis.
Timepoint [1] 257445 0
10 - 12 hours following intercourse at the time of the LH surge during a menstrual cycle
Secondary outcome [1] 262582 0
A blood sample will be collected at the time of endometrial biopsy to determine any effect of seminal fluid on number and phenotype of circulating T lymphocyte populations.
Timepoint [1] 262582 0
10 - 12 hours following intercourse at the time of the LH surge during a menstrual cycle

Diagnosis
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All subjects will be enrolled for the intervention and control cycle.
There will be no allocation concealment procedures.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer generated randomisation schedule will be used to allow allocation of intervention sexual intercourse with or without condoms or abstain during the intrevention cycle.
Subjects will have the intervention cycle first followed by the control cycle.

Summary
Brief summary
Healthy reproductive function is essential for conception and pregnancy. We have discovered that male seminal fluid can influence the female reproductive system after coitus. This project will define the actions of seminal fluid in the cervix and uterus, and the impact on fertility and defence against sexually transmitted infection. The findings will provide new insight on how men contribute to reproductive health in women, and lead to improved treatments for infertility and miscarriage.
On the basis of our extensive studies on the female response to seminal fluid in animal models, and observations to date in human tissues, we hypothesise that in women, male seminal fluid interacts with epithelial cells lining the cervix and endometrium to activate a similar but distinct inflammatory cytokine response in both tissues.
