This involves empowering school girls with information on the danger associated with defilement.
The leaders also liaise with law enforcement agencies to ensure people who violate the sexual rights of girls are apprehended.
This was revealed during a school girls' empowerment programme dubbed 'Mama County Back to School' organized by Osogo's office.
The event held at Mirogi Boys High School brought together girls from various schools from all the eight constituencies.
Wanga said the fight against teen pregnancies requires concerted efforts from all stakeholders in the county.
The governor said she will not entertain anybody who violates the sexual rights of minors in the county.
According to her, the young girls should be given the requisite protection to enable them to acquire education. She said it is through education that many girls in the county will become leaders in the future.

"Let us protect our girls from people who want to ruin their lives. As one of the current leaders, we are headed for retirement and the people who will take over from us are these girls. Ruining their lives today means we will not have future female leaders," Wanga said.
She told girls to be focused on their education to avoid being hoodwinked into premature sex.
"I want our girls to stand firm against those who want to defile them. Let them focus on their books," Wanga said.
Dr Osogo said they are committed to ensuring girls who dropped out of school due to teen pregnancies return to school.
She said the objective of the programme is to ensure girls are retained in schools.
"We want every girl to acquire an education. That is why we are supporting teen mothers to return to school," Osogo said.
