Transgender Frogs


What would you do if you were a boy that started to grow eggs in your testes? This probably sounds strange, but this is happening to frogs that are exposed to one of the most widely used herbicide, Atrazine.

Pesticides and herbicides are full of chemicals made to kill certain things- whether it be plants or bugs. If they’re able to kill weeds, imagine what they could be doing to us. Pesticides and herbicides can run off from farms into nearby streams and rivers and end up in our water. In fact, you've probably been exposed to this chemical when eating, drinking water, or even playing sports. Atrazine is often used for killing weeds and is even found on turf. It is so widely used in the United States, that it is the most commonly found pesticide found in drinking water.

Atrazine is very harmful because it is an endocrine disruptor, meaning it disrupts the hormones in your body which send signals to your cells. This finding that atrazine can change frogs' genders is so significant because frogs are an indicator species. They indicate the true effects that a chemical can have in high amounts. So if frogs are suddenly growing eggs in their testes, imagine what this could be doing to humans.

In humans, Atrazine causes hormonal disruption, harmful effects on the reproductive system, and is linked to an increased risk of breast and prostate cancer. Also, even though Atrazine is so widely used, recent analysis prove that they are not that significant in maintaining plant growth and would result in less than 1% of yield losses. So, is that extra 1% worth our health?

Clearly, Atrazine causes harmful changes, but luckily it can be easy to avoid. Buying Organic products and supporting local farmers ensures your own health and allows organic farmers to continue farming naturally. Also, you don’t need to buy all your foods organic. Some foods such as EWG's Clean 15, are less susceptible pesticides. Even if you can’t buy everything organic, even the smallest changes can have a great impact.
