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 progesterone and estrogen levels were measured in 5 healthy women during treatment with an oral

contraceptive containing 37.5 mcg of ethinyl estradiol and 1 mg of lynestrenol (Ovostat 1375). Blood samples were

obtained daily during 1 control cycle and every other day during 3 consecutive cycles. The estrogens were measured

by radioimmunoassay and progesterone by competitive protein binding and by radioimmunoassay. Irregular bleeding

generally occurred only during the 1st treatment cycle. The very low levels of progesterone and the absence of

ovulatory peaks of the estrogens suggested that no ovulations occurred during treatment. Estrogen levels during

treatment were lower than early follicular phase levels during the normal cycles although overlapping of values

occurred. The estradiol estrone ratio was 1:2 during treatment and 1:1 during the early follicular phase of normal

cycles. When treatment was started during the midcycle rise of estrogens, no rise of progesterone was seen. It is

concluded that the lynestrenol is likely to be partly responsible for the inhibition of ovulation and the additional

suppression of steroidgenesis. (PubHealth.info Document ID: CONT7T 3062-06)
