Due to semi-tight foreskin, I am compelled to use lubrication for penetration. I have used sing organic coconut oil, ky jelly , lubic gel. My wife not conceived till now. All the tests of mine and her ( semen analysis,
TSH,
FSH,
prolactin,
testosterone etc. ) Etc. Of both of of us are normal. Is the infertility due to using lubricant? Please suggest a lubricant that is sperm friendly
