Since Vedic period, to have healthy and long living children has been desired, whereas infertility has been considered as a cursed condition and is looked as a medico-social problem. According to Ayurveda, Shukra is considered as the essence of all Dhatu and Garbhotpatti is its prime function. Dhairya, Preeti, Dehabala and many other psychosomatic factors depend upon the status of Shukra. Today, increased mental stress, faulty eating & life style have endangered reproductive capacity of men, leading oligozoospermia (Ksheena Shukra) and asthenozoospremia and ultimately to infertility. Oligozoospermia and Asthenozoospremia can be the result of many factors, which may be permanent or reversible. It may result due to an obstruction of the normal flow of sperm such as in testicular trauma or vasectomy. Oligozoospermia and Asthenozoospremia may also result from scarring due to surgery on the male reproductive system or from infection and sexually transmitted diseases. Other causes are disorders of testis, reduced synthesis of testosterone or defective spermatogenesis. Recent studies have revealed that the problem of male infertility is on the rise in the country. Rough estimates suggest that nearly 30 million couples in the country suffer from infertility, making the incidence rate of infertile couples at 10 per cent, and in 40 to 50 per cent cases, the male is the affected partner. Out of several causes of male infertility, in clinical practice Oligozoospermia and Asthenozoospremia are considered as one of the most prevalent causes. Though the problem is on the rise, the good part is that 80 per cent of the infertility problems can be corrected through simple medication.

Further, on the basis of various research conducted by Carlsan et al, between 1938 to 1988, it is relevant that sperm count, has come down from 130 million/ml of semen to 66 million/ml of semen. Various modern therapeutic measures and associated reproductive technologies like artificial insemination, test tube baby etc. are very expensive and common man cannot afford for it. Further results are not very encouraging. Hence, there is a search for alternative treatment modalities in other system of medicine, which is safe and cost effective.

This is reason why; today to explore fertility agents from herbal source is of top priority in the field of research in Andrology. WHO report also states that, good evidence of efficacy exists for some herbal medicine, but evaluation is inadequate. Considering these facts, Capsule Spark containing some of the most potent Vajikarana drugs mentioned in classics like Ashvagandha, Kapikachu, Gokshur, Shatavari, Vidarikand, Jatiphala, Bala in the form of extract with powders of drugs like Narsinha, Shveta Musali, Shuddha Shilajatu, Maricha, Shunthi and Pippali was formulated.

Hence, present study is planned to evaluate role of Capsule Spark on seminal parameters with special focus on Oligozoospermia and Asthenozoospremia and possible effect of this trial drug on the hormones FSH, LH and Testosterone levels, which also contribute in spermatogenesis.
