Reproduction has been difficult to study in the wild.
The Orsini’s viper is
ovoviviparous(1)
and the females cycle is essentially bi annual. Coupling takes place
towards the end of May and between 3 and 8 young are born between the end
of August and the end of September when they go straight into hibernation
and do not eat until June the following year.

It would appear that the principle problem for this
snake is Human activities, roads, ski runs, tourism and theft by reptile
dealers and collectors. It is also eaten by Short toed Eagles, Buzzards, Montagu’s
Harriers and Ravens.

Population in steep decline –
Endangered
VENOMOUS
(1) Animals that retain the eggs within the body of the
female in a brood chamber in which the development of the
embyo takes place, perhaps deriving some
nourishment from the female, but without the strong umbilical attachment
to a placenta as in mammals; the typical condition of so-called
"live-bearing" fishes. Also called aplacental
viviparous. The young hatch inside the mother's uterus from their thin egg
capsule, and are usually born shortly afterwards
