Reproduction
Both sexes reach sexual maturity at four years when they are about two feet in length. The breeding season is from February to May and from August to October. Males seek out sexually active females using their tongue to detect pheromones in the air. Once he has located a female, the male begins moving his head or rubbing his chin on the ground. Eventually, after courtship, the male aligns his body with hers. This courtship may last for an hour or more if the female does not respond. After being sufficiently stimulated, the female lifts and arches her tail and lowers the scale that covers her cloaca. Then the male arches his body and tail, everting one of his two hemipenes and mates with the female. Mating time varies; ranging from as long as 3.5 to 8.5 hours. The long mating time could correlate with the fact that females usually only mate with one male per year. During the mating period, males produce a pheromone that makes the female unattractive to other males, which pay little or no attention to mating or just mated females. Females also have little interest in mating after a long, successful first mating.
Females that breed in autumn store the sperm until after emerging from a hibernating site. The length of time that the sperm can be stored appears to differ depending on where it is being stored. If the sperm is stored in the cloaca, it lasts a relatively short time, whereas if it is stored in the upper end of the oviducts in vascular tissues specialized as seminal receptacles it seems to last much longer. Copperheads have a gestation period of three to nine months. They are a live-bearing snake, typically producing two to ten young; larger females produce larger broods. After birth, the female provides no direct care for the young.
Females are ovoviviparous (eggs develop in the body of the female and hatch within or immediately after being expelled). They produce large, yolk-filled eggs and store the eggs in the reproductive tract for development. The embryo, during this time, receives no nourishment from the female, only from the yolk. The young are expelled in a membranous sac and weigh less than an ounce (28 g) and measure seven to ten inches (17.8 to 25 .4 cm) in length
