Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Instruction (presented as a face-to-face session for approximately 40 minutes) in the Sympto-Thermal charting Method lasting, documented on a temperature/mucus chart for up to 8 months.
This will occur in addition to the instruction in fertility awareness (group session for 20 minutes) that both trial arms will receive.
Intervention code [1] 284175 0
Other interventions
Comparator / control treatment
Instruction in fertility awareness (presented as a group session for approximately 20 minutes); the first day of each menstrual cycle documented on a calendar for up to 8 months.
Control group
Active

Outcomes
Primary outcome [1] 286417 0
Positive pregnancy test.

This is defined as HCG > 25 mIU/L. This test is either a quantitative serum level or a qualitative urine point of care test (which becomes positive at a level of 25 mIU/L).
Timepoint [1] 286417 0
Pregnancy test is to be performed in the setting of a clinically missed period (for those charting this is 16 days after peak mucus sign or 15 days of sustained temperature shift) for up to 8 months

Summary
Brief summary
This project will assess the effectiveness of a fertility awareness-based charting method in increasing the likelihood of pregnancy in a population with unexplained subfertility.

It is hypothesised that the Sympto-Thermal Method increases the likelihood of pregnancy in the unexplained ovulating subfertile population.
