What is a commonly used method for surgical sterilization in females?

1. Removal of both testicles

2. Scrotal Approach

3. Complete Ovario-Hysterectomy

4. Vasectomy

The correct answer is: Complete Ovario-Hysterectomy

The commonly used method for surgical sterilization in females is a complete ovario-hysterectomy. This procedure involves the surgical removal of both the ovaries and the uterus, effectively preventing any possibility of pregnancy and eliminating the heat cycle in female animals. By removing these reproductive organs, the procedure not only prevents future litters but also reduces the risk of certain health issues, such as uterine infections or ovarian tumors. Other methods like vasectomy, which involves cutting the vas deferens in males to prevent sperm release, and scrotal approaches are specific to male animals and do not relate to female sterilization. Removal of both testicles is a technique for male sterilization, specifically called castration, and therefore does not apply to the female sterilization context. The complete ovario-hysterectomy is thus the correct choice as it directly addresses the surgical sterilization needs in females.
