Terry Nett working with an elk in Rocky Mountain National Park

 Dr. Terry Nett directs a study on contraception in wildlife species. Here he is working with an elk in Rocky Mountain National Park.

Fertility, Sterility, and Contraception

The ARBL focuses on understanding the most basic reproductive mechanisms (e.g., hypothalamic-pituitary, ovarian, uterine, testicular, immune, etc.) and then applies this information to manipulating reproductive endocrinology and processes. 

The exploding human population is putting extreme burdens on all aspects of life and the environment. Some species are becoming endangered, while valuable resources are being consumed by excessive populations of other species. In addition, we will have to produce as much food in the next 40 years as we have in the entire history of mankind to avoid major famines and starvation in large areas of the world. The common solution to these apparently conflicting issues is to develop better methods for regulating reproductive processes. 

Management of animal populations is a critical global challenge for the welfare of the planet, but one that scientists at CSU and in the greater CSU community are well-positioned to address. These challenges can be broadly grouped into three categories, each of which is impacted by growth of the human population: 

  1. ​Numerous animal species are becoming endangered for a variety of reasons, primarily as the result of loss of habitat stemming from the burgeoning human population or from environmental decisions that impact multiple species. 

  2. Several species have become overpopulated due to restrictions that protect them or due to the fact that they live in areas where accepted management practices cannot be used to control their numbers. 

  3. World populations of domestic livestock must be managed to maximize their efficient conversion of forage resources and byproducts (that are otherwise unsuitable for human consumption) into high-quality protein in meat, milk, and eggs.
