Thanks for your query .You are trying for baby but not getting conceived due to some problems that both of you have.As regrds your wife does she have normal ,regular menstrual cycle because ovulation occurs only when the menstrual cycle is regular..
As regards your semen count and morphology is reported it variable at three different intervals.So please get it done in a renowned Andrology Lab where examination of the semen is done by trained and expert personals.As per your semen analysis
your count is low and %tage of active mobile sperms is also below than what is required for fertilization.to result.There are no medicines that can improve the sperm count
or morphology of sperms.
I would advise you to consult some Infertility
specialist for proper evaluation of both of you and He will be best person to decide regarding other options like IVf or ICSI
