How FSH and LH analogs affect fertility hormone results?

Summary: When couples need help having a baby, doctors often use special fertility drugs to help them get pregnant. This study looked at how these drugs might mess up standard blood tests for hormones. The researchers found that the drugs can cause huge mistakes in the test results, especially for hormones called FSH and LH. Sometimes the test results were completely wrong by massive amounts! Because of this, doctors need to be very careful when reading hormone test results for patients taking these fertility medicines, so they don't make the wrong medical decisions.
