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

While initially it was believed that oral contraceptives acted by inhibiting ovulation, research showed that they can

act at different points in the hypothalamus-hypophysis-genital system and in different manners, depending on the

type of drug and the therapeutic method. They may affect either the hypothalamus or the hypophysis, suppressing or

limiting the release of one or both gonadotropins, or on the components of the ovary, or the fallopian tubes, the

endometrium or conception itself, by alterating the transportation of ovules or the timing of implantation, or on

cervical mucus, causing it to prevent the penetratio n of sperm, or by eliminating the prerequisites for the

capacitation of spermatozoids. The antibiotic valinomycin has been demonstrated to be an inhibitor of adenyl-

cyclase in a number of systems. In tests on rabbit blastocyst cultures in the presence of valinimycin, the expansion

of the blastocysts was significantly reduced in a few hours as a result of severe disruption in the cellular substance.
