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 effect of contraceptive steroids on serum progesterone and estradiol levels was determined. Progesterone was

assayed by both competitive protein binding and radioimmunoassay and estradiol by radioimmunoassay. The Celite

column chromatographic method was used in all steroid assays. Assays were done in control cycles and in 2 drug

treatment cycles of 3 women taking oral contraceptives. The progesterone remained low and undetectable by

competitive protein binding. Estradiol values were low and remained at early follicular phase value. No midcycle

surge or any luteal phase rise in estradiol was observed. Ovarian activity was considerably reduced in the 1st and

2nd treatment cycles, and follicular growth ovulation, and luteal development were inhibited. Follicle stimulating

hormone (FSH) values were low whereas luteinizing hormone (LH) values showed fluctuation. Midcycle surges of LH

and FSH were absent. Ovarian activity was reduced relative to the secretion of estradiol and progesterone.
