Tag: Hcg trigger

For those undergoing fertility treatments, the timing of an hCG trigger shot is crucial for inducing ovulation, but a common source of anxiety is how long the medication remains detectable in the system. A 2020 study highlights the wide inter-individual variability, showing that factors like body mass index (BMI) can influence how quickly the body metabolizes the hormone. This lingering presence of exogenous hCG is the reason a home pregnancy test can show a false positive, causing significant emotional distress.

Over 70% of women using injectable FSH fertility medications like Fostimon may ovulate successfully within their first cycle, with success rates improving with subsequent cycles. However, many patients ask, **how long does Fostimon take to work?** The timeline is not a single event but a multi-step, personalized process focusing on stimulating follicle growth over days before a final trigger induces ovulation.
