1.Objective To investgate the treatment of asthenospermia and necrospermia infertility with percutaneous vasal sperm aspiration ( PVSA) and intrauterine insemination ( IUI) .
9.One benefit of artificial insemination is that it does not require elephants to be transported from zoo to zoo, which is expensive and can be traumatic for the animals.
10.There is a catch, though: artificial insemination in African elephants with semen that has been frozen, as opposed to the fresh stuff, has not so far been done successfully.
11.Other animals, as well as humans, have been successfully bred through artificial insemination, but perfecting the process in dogs took decades because of the critical timing in fertilization of the female dog's eggs.
