According to Ayurveda, preparing for conception can be easily compared to the process of farming. Just like the health of a crop depends on the quality of soil, seed, timing of sowing, and amount of watering it gets, the health of a baby depends on the health of its parents. For a pregnancy to be healthy and successful, a couple needs to take care of the following four essential factors: Sperm/Ovum (Seeds), Uterus (Soil), Nourishment (Water), Time for Conception (Timing of Sowing). Reproductive health, in both men and women, depends on the health of the reproductive tissue or shukra dhatu. In women, shukra creates the ovum as part of the monthly cycle, and in men the semen is formed due to sexual stimulation. The shukra is created as part of a long chain of metabolic transformations. It starts with the digestion of food, then goes on to transformation of food to nutrient fluid, blood, muscle, fat, bone, bone marrow, and finally, to shukra tissue. Healthy shukra tissue, then, according to Ayurveda, depends on the health of all the other tissues in the body.
