Summary

This trial studies how 1 type of birth control pill affects knee movement & joint instability in female athletes, & compares it to athletes not on birth control.

Who is the study for?
This trial is for female athletes over 18 who play basketball, soccer, or volleyball at Loyola Marymount or Pepperdine. Participants can be on birth control pills or not but should have regular menstrual cycles if they're not. They can't join if they've had an ACL injury before, neuromuscular disease, health reasons preventing birth control use, a history of pregnancy, or plans to conceive soon.
What is being tested?
The study tests whether a common oral contraceptive pill affects the blood levels of relaxin and knee movement in female athletes. It aims to see if the pill changes joint stability and potentially lowers the risk of ACL injuries by comparing those using it with those who don't.
What are the potential side effects?
While specific side effects are not listed for this trial, typical side effects from oral contraceptives may include nausea, weight gain, mood changes, menstrual spotting between periods and breast tenderness.
