===== Frequency =====
Statistical estimates suggest that fecund ability rises sharply with frequency of intercourse. It is observed in a study that 94% of women aged 35 years and 77% women aged 38 years are conceived with regular intercourse for three years. [ ] The risk of erectile dysfunction in males aged among 30 to 75 years can be reduced by maintaining a regular frequency of intercourse. [ ] Coital frequency is directly related to conception. Research shows that best sperm motility is found in semen emission every three to four days on average.[ ] Intercourse every two to three days can maximize the overall chance of natural conception because spermatozoa can survive for up to seven days after insemination in the female reproductive tract.[ ] So, regular coitus with 3-4 days gap should be regarded as optimum coital frequency.

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. [ ]
