Hi, Thanks for posting in HCM. I understand your concern. Semen is more watery watery in consistency and could be related to ejaculation frequency, hydration status and diet. Watery sperm can be caused by a low sperm count, insufficient zinc intake and a fructose deficiency. Your semen consistency should become thicker by decreasing the frequency of ejaculation, keeping yourself well hydrated and consumption of fructose rich diet like honey and fruits. You could be experiencing back pain due to generalised weakness. Kindly take foods rich in iron and supplement iron by means of medications. Also, take protein rich diet and supplement protein in the form of powder to be mixed and taken with milk. Gradually, you will overcome this problem and should be back to normal. Hope the information provided would be helpful. Wish you good health.
