Although there is a lot of treatment to increase sperm count and motility, I would suggest you adopt Ayurveda for this, it will not harm you and along with it slowly your problem will be completely eliminated.
In the quality of herbs and especially your problem, I would suggest you two products of Ayurveda. 1. Saint Ayurveda's Vasnik Capsules: This product contains abundant and important herbs like Ashwagandha, Konch, and Gokshru. This will thicken your semen and help in increasing your sperm count.
Another suggestion is that using this product, Temple Herbals Yoman will remove your problems like premature ejaculation, dreaming and it will add energy to you. Both of these products are very effective and reliable.
Vasnik Capsules will be the most effective for your problem and if you feel weakness in your body and lack of stamina, then you can use the product of Temple Herbals yoman.
