Lavender oil

Not sure where to post this but hoping for some feedback. My friend just called me with a question about lavender oils. We both use a coconut oil and lavender oil mix for our kids diaper rashes. We use doterra oil and the coconut liquid. Mixed correctly. But someone had told her that lavender oil can mess with testosterone levels. Everything we have read is a mix of yes and no. I've never even thought to look into this because I only have daughters. Does anyone have any information on this?
