“…Using the same OC agent used in our study (ethinylestradiol 35mcg/ norgestimate 0.18/0.215/0.25 mg, or Ortho Tri-Cyclen®), Burkman et al reported no significant changes in fasting glucose or insulin levels, or glycosylated hemoglobin in a 2-year study conducted in 1783 healthy women (7). Similarly, monophasic formulation of this combined OC (35 mcg ethinylestradiol/ 0.25 mg norgestimate) in 42022 women (342,348 menstrual cycles) also suggested little effect on lipid metabolism and fasting glucose (19). However, neither of the of these latter studies directly evaluated insulin sensitivity.…”

“…COCs reduce the incidence of dysmenorrhea by 60%, leading to fewer school and work absences and a reduction in pain medication requirement 64,65 . They also decrease blood loss by shortening the number of days of menstruation 66,67 . This reduction in blood loss leads to a decreased risk for iron‐deficiency anemia 68 .…”

“…Entre los numerosos ensayos clínicos con preparados por vía oral, destaca el de Runnebaum y cols. (177), quienes diseñaron en Alemania, un ensayo multicéntrico, abierto, no comparativo, realizado con una muestra poblacional de 59.701 usuarias, seguidas durante 12 meses (342.348 ciclos). Estos autores, evaluaron la eficacia y seguridad de un preparado monofásico de NGM (250 μg) / EE (35 μg), obteniendo un Índice de Pearl (IP) de 0,25.…”

“…La incidencia de sangrado irregular, también se recoge como una de las razones para abandonar la anticoncepción hormonal (171). En los estudios llevados a cabo con NGM y NGNM, se ha reportado una incidencia de sangrados irregulares, equivalente a la de los otros tipos de anticonceptivos hormonales, disminuyendo en el caso de los STL hasta desaparecer en el ciclo 13 (12,177). En el caso de los STL con NGMN, hay que considerar que el manchado intermenstrual, puede ser algo superior en los dos primeros ciclos, pero disminuye progresivamente en los ciclos sucesivos.…”
