With the example of elephant, the second parameter of semen volume is mentioned. According to WHO guidelines, the normal semen volume is 2.0–5.0 mL. Adequate volume of semen is required to carry male gametes into the female reproductive tract. Therefore, ejaculate volume is an important component of a semen analysis done to investigate male factor infertility. [ ]

Effect of seasonal and individual variation on virility of a person has been mentioned. A particular code of conduct based on season has been told for coitus frequency.

Human conception follows a seasonal rhythm.[ ] Seasonal modifications of reproductive functions[ ] and semen parameters[ ] are documented in human males. Recent trends noted a decline in relation of seasonal variation and human conception rhythm. The increased industrialization leading to increase in people being shielded from both photoperiod (by indoor work) and temperature (by heating and air conditioning) might be the reason behind this.

In present era, even with availability of sophisticated diagnostics in approximately 15% to 30% of couples we are unable to find out the exact cause of infertility. [ ] Ayurvedic Scholars included all conditions in which no evident cause of infertility was seen under broad term ‘Prakritya’. The second important cause for infertility which is observed was affliction of diseases. A person who is afflicted with diseases gets debilitated and this result in decrease in fertility/virility. This is another important principle and it shows scientific vision of ancient Ayurvedic scholars.
