Официальное название
A Three Month Course of Power Prenatal Supplements to Improve Sperm Quality in Male-factor Infertility Patients
Обзор
Male factor infertility is a leading cause of primary and secondary infertility. Poor sperm quality is defined as having an abnormal semen analysis \[WHO 2020 - https://www.who.int/publications/i/item/9789240030787\]. The effects of supplements (vitamins, minerals, and anti-oxidants) on improving sperm quality are still debated (https://pubmed.ncbi.nlm.nih.gov/30462179). 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 based on semen analysis results prior to, and after taking the supplements.
Подробное описание
Male patients presenting to Conceive Health (https://conceivehealth.com/) or Reproductive Care Centre for infertility care will be potential candidates for this study. Male patients that have had a recent abnormal semen analysis conforming at least 1 of 3 parameters (low concentration: \< 15 Million / mL; low progressive motility \< 30%, and low morphology with strict criteria \< 4%) will be eligible to participate.
Patients will be approached by a study coordinator to participate in the study. The study coordinator will ensure all inclusion and exclusion criteria is met, consents forms are signed, and a 90 day course of the "Power Prenatal for Sperm" is dispensed
Study participants will be instructed to repeat a semen analysis (at the same lab) after their 90 day course of the "Power Prenatal for Sperm". The differences between the semen analysis parameters will be compared
The primary outcome was chosen as processive motility, as this parameter is mostly likely to be positively impacted by the Power Prenatal for Sperm.
An abnormal progressive motility is defined as \<5th percentile (32%) of the semen analysis of the fertile male population. The standard deviation for this population is 13.5%. The estimated effect size is 37.5%, from 32% to 44%, an increase of 12%. The alpha (type 1 error) significant level was set at 5% and the power level was set at 80%. The required sample size was 40 patients. Given that this study requires a 3 month intervention prior to a follow up semen analysis for comparison, the investigators estimated a 20% drop-out rate, so the total requirement was set at 50 patients.
Table A1.2 (https://www.who.int/docs/default-source/reproductive-health/srhr-documents/infertility/examination-and-processing-of-human-semen-5ed-eng.pdf)
Statistical analyses will be performed using standard expected methods. All data will be presented as mean ± Standard Deviation (SD). Statistical significance between semen analysis data will be determined by using the Shapiro-Wilk test of normality for predictions and paired samples t-test.
