My husband loved it. He had been diagnosed with low testosterone several yrs ago in his early 30s. At 39 or 40 he was placed on testosterone from depression. For people who don’t know , Testosterone treatments make you sterile over time. My husband and I started to try conceiving a baby in April 2017, for months nothing happened, finally they tested my husband. Zero sperm was the diagnosis. We did our research found out testosterone was the culprit. 4 month later more tests and visit to a fertility clinic they said his sperm volume and health were not good enough to ever conceive a child natural, invitro would be our only chance. I was determined to try everything natural. Found fertilaid Through Research, put hubby on it in March 2018. We also both went on a diet and exercise regimen, to improve both our overall health. May 2018, 3 months into using fertilaid we are pregnant 🙂 :)… I can’t say fertilaid was the only reason. I can however say that my husband tested for normal testosterone for the first time in several yrs, and even though we are pregnant we still just ordered more fertilaid because it just makes my husband feel more balanced without any negative side effects just the positive ones like increased libido :):)… I am 37 and my husband is 43 we could not be more happy with this product :).
