• Some tests also measure E1-3G to identify the user`s wider fertile phase.
• Such tests require users to test the first morning void.</

Low levels of hCG are known to be co-produced with FSH during reproductive aging (during peri-menopause and menopause). A missed period could be indicative of pregnancy or peri-menopause for woman in later reproductive life, so understanding the reference ranges for hCG is important.

This study sought to determine whether timing of nFET using home ovulation tests (OT) is a viable alternative to multiple clinic visits.

• nFET requires tracking of hormonal and endometrial changes in order to identify the day
