About the study
Male factor infertility is a leading cause of primary and secondary infertility. Poor sperm quality is defined as having an abnormal semen analysis.
There are now options to assess sperm quality with at-home sperm analysis kits, including an FDA approved Yo Sperm kit (https://yospermtest.com/) which analyzes the motile sperm concentration \[concentration (millions / ml) x motility (Percentage motile)\] and sperm quality (YO Score) which compares your results to laboratory standards and to other men who have fathered children.
The effects of supplements (vitamins, minerals, and anti-oxidants) on improving sperm quality are still debated. Taking additional supplements to improve sperm quality represent a modifiable risk-factor that would be an easy intervention for patients struggling with male factor infertility.
The life cycle of sperm production is estimated at 3 months, so any intervention would require a 3 month course to see its full effect.
The investigators hypothesize that a 90 day course of the "Power Prenatal for Sperm", a male fertility supplement by Bird\&Be (https://birdandbe.com/the-power-prenatal-for-sperm) will improve sperm quality (YO Score) after taking the supplements.
