Hello
Thanks for query .Based on the information that you have provided your 
semen analysis has revealed your 
sperm count to be very low and percentage of active grade one motile sperm is also low (Oligoasthenozoospermia).
Truly speaking these abnormality are due to chromosomal abnormality and can not be cured with medications .
There are many drugs being sold in market and being prescribed by physicians but not even a single drug has been proved scientifically effective to prove their claim .However following general measures do help to some extent to improve  sperm count and sperm motility
1) Practice regular exercise for 45 minutes followed by 
meditation for 1/2 an hour in the morning.
 2) Take high protein diet rich in vegetables and fruits and Vitamin     A,C,D,E.and Zinc 
3)Take anti oxidants like Almonds 5-6 everyday
4) Avoid alcohol and smoking..
Taking Sildenafil  (Viagra) or Cialis as on demand will help to get good hard sustainable erection and to have enjoyable sex.
I would suggest you to consult qualified 
infertility specialist for detail evaluation and explore possibility of conception with the help of newly 
assisted reproductive techniques like IVF or ICSI .
