None of these variables significantly affected the pregnancy rate or the percentage of transferred embryos developing to term . The researchers found no pregnancy rate differences between adolescents in schools with and without condom availability programs , possibly because sexually active students in schools without condoms available were more likely to use non-condom contraception . All types of myomectomy ( laparoscopy , laparotomy , or hysteroscopy ) increased the pregnancy rates .
