Each time he lures and mates with the female, the male takes about 18 hours a day, and consumes about 10% of the energy during mating season.

While the older males age, the ratio of normal sperm is higher, up to 85%, and the beautiful, colorful males start to decline earlier. If a male at age 15 mates 30 days a year, the ratio of normal sperm is 79%, while mating 180 days (equivalent to 6 months), that ratio can only be 73%.

Research may indicate that one of the causes of aging in biological development is reproduction , said researcher Brian Preston.
