Hallow Lawyer,
There are many medicines which help in assisting the conception. However, each medicine is fault specific.
Problems in fertility could be due to either fault in man or woman.
The fault in man could be low or unhealthy sperms. Depending up on the fault, the treatment changes. If there are any transport problems, the treatment differs.
In woman, the faults can be grossly trifurcated into non formation or release of eggs, unfavourable uterine environment and block in the genital tract not allowing the sperms to meet the egg. Each fault needs a specific treatment.
There is no blanket treatment for
infertility without knowing the cause behind it. You cannot defend your client if you do not know the offence. It is just like that.
Please take help of a Gynaecologist to pinpoint the cause of infertility. For the diagnosis, you will have to undergo a battery of investigations. Once the fault is detected, the case can be managed effectively and scientifically.
Since you have conceived previously, the chances are good however, your age is against the good chances.
I am sorry, I could not answer to your expectations; however, I have answered scientifically and logically. Please take my advice healthily.
