PubHealth.info® (a subsidiary of PakMed) presents scientific information mainly based on abstracts of articles published on a variety of public health issues/topics, particularly encompassing population planning, disease prevention, maternal and child health, and communicable and non-communicable diseases (like HIV AIDS, malaria, etc) that are affecting a significant portion of population in developing and developed countries. Here you can find abstracts of articles published on a variety of public health topics under category "Contraception (Birth Control) and Family Planning". Contraception (birth control) is a regimen of one or more actions, devices, or medications followed in order to deliberately prevent or reduce the likelihood of a woman becoming pregnant or giving birth. Therefore contraception is the utilization of various and sundry surgical procedures, devices, practices, agents, or drugs with the intention of preventing conception or impregnation (pregnancy). Methods and intentions typically termed birth control may be considered a pivotal ingredient to family planning. Birth control is a controversial political and ethical issue in many cultures and religions, and although it is generally less controversial than abortion specifically.

ABSTRACT

The mechanism of action of levonorgestrel (LNG) and mifepristone (MIF) in emergency contraception (EC), is still not

fully known. The purpose of this study was to evaluate the effect of preovulatory treatment with LNG and MIF on luteal

function in more detail. Two days prior to ovulation (day -2; assessed by ultrasound), we administered LNG (0.75 mg

twice, 12 h apart) or MIF (10 mg, single dose) to seven women in different cycles. Follicle development was followed

by ultrasound. Urinary estrone glucuronide (E1), pregnanediol glucuronide (P4) and luteinizing hormone (LH) were

analyzed by enzyme immunoassays daily starting with day -2 for the rest of the menstrual cycle, along with urinary

creatinine (C). The treatment caused either a delay or an inhibition of the LH peak in all subjects. A significant delay

in P4 levels and an initial suppression of E1 levels were also noted. The development of the leading follicle was

either arrested or continued without signs of rupture. This study indicates that, when used for EC, LNG or MIF

administered prior to ovulation acts through an impaired ovulatory process and luteal function. (PubHealth.info
