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

Plasma luteinizing hormone (LH), estradiol, progesterone, 20alpha-hydroxyprogesterone, and testosterone were

radioimmunoassayed daily throughout a normal menstrual cycle, the 3rd, 6th, and 9th cycles during oral

contraception with Stediril, and during stimulation with LH-releasing factor (LH-RF), human menopausal

gonadotropin (HMG), and human chorionic gonadotropin (HCG). 6 women aged 23-30 took Stediril (50 mcg ethinyl

estradiol and .5 mg norgestrel, combined) for 1 year. I n the control menstrual cycle, LH rose to a plateau in the

follicular and luteal phases, and a high midcycle peak; estradiol rose progressively until its midcycle peak, then fell

and rose again; testosterone varied with higher peaks at midcycle; progesterone began to rise on the day of the LH

peak to a maximum 5-9 days after ovulation; 20alpha-hydroxyprogesterone resembled progesterone but at a lower

magnit ude. During pill cycles, the subjects took 1 mg dectancyl every 6 hours starting the day before blood

sampling to inhibit adrenal corticosteroids. LH, estradiol, and progesterone were very low and invariant from Days 9

to 18. 50 mcg LH-RH elicited a significant LH peak (90-370 ng/ml) within 15-30 minutes. 75 IU FSH did not

stimulate formation of a corpus luteum in 3 subjects taking 4 mg dexamethasone per day, although 150 IU FSH

caused a corpus luteum to develop in 1 of 3 not taking the corticosteroid. Thus LH, estradiol, and progesterone

secretions were incompletely inhibited by Stediril. (PubHealth.info Document ID: CONT7T 3060-06)
