hello Thanks for query .Based on your statement your semen has become thinner and less viscous compared to what it was theree months before This could happen due to following reasons 1)The quantity of sperms which is the main constituent of semen and responsible for viscosity is low 2) Excessive secretion of mucus by Bulbo Urethral glands located in Urethra due to masturbation being prolonged for a long time . 3) Frequent masturbation over a short period of time . You need to do Semen analysis with abstinence of 4 days prior to collecting semen sample and same should be given for analysis within half an hour after collection .Following measure will help you to improve quality of semen 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.
