Two types of medicines are there
Hello Young man ,
Thanks for using Healthcaremagic.
I am sorry for your wife's abortion
You mentioned that you have 5-8 days night duty and only during that period you have erection problem. This suggests that your disturbance is due to changing of your bilogical circadian rhythem. It means changing of your sleeping and working time.
You can have following options to treat the problem.
During nightshift period, if you have difficulty in sleep in daytime zolpidem
can be used.So if you will be able to get good sleep and rest your performance would increase.
During nightshift time you have to do intercourse in day time, so during this try to create atmoshphere of your bedroom like night as sometime sex in the day can not be perform well by some couple.
If these not work, you can have tadalafil
during nightshift period just an hour before sex.
Whatever medicines I have mentioned to be taken after doctor's consultation.
And your concern for baby: to have a baby successful intercourse needed during woman's ovulation period of menstrual cycle.
Means roughly counting if you have a succsseful sex during 13th to 16th day of your wife's menstrual period chances of her become pregnant more. So just note this days and if feasible avoid nightshift during and around these days so you can have normal erection without any medicine.
Late me know her last menstrual cycle information and her menstrual history menas how many days it last and total interval between two cycles, so I can tell you specifically about her next fertile period.
All the best.
