Thank you for your kind visit to PubHealth.info®, an information portal created in technical collaboration with PakMed Biomedical Solutions * * * PubHealth.info® presents hundreds of thousands of informative Web pages on a variety of public health issues / issues * * * An ultimate source of information for teachers, students and research workers who need to find information on various public health issues, like population planning, contraception, HIV AIDS, STDs, maternal and child health, communicable and non-communicable disease, etc. * * * PubHealth.info® regularly updates the repository of these hundreds of thousands of informative Web pages * * * PubHealth.info® is one of the world's largest repositories and information portals with online Web pages on public health issues particularly those pertaining to developing countries!

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

There are several possible new contraceptives on the horizon. For example, there are at least four second generation

Silastic implant contraceptives similar to Norplant in development. These new systems have fewer numbers of

implants than Norplant, which will make removal easier. Norplant 2 consists of only two rod implants instead of the

six in the original Norplant system, while single-implant systems are also being developed. A biodegradable implant

is also being researched; such a device would not have to be removed once its expected period of service

transpired. A vaccine to prevent pregnancy is also being studied, with the most comprehensive research program

being conducted currently in India. Vaccine research sponsored by the World Health Organization has also taken

place in Australia. A version of a vaccine could be ready in India some time after the year 2000. On yet another front,

researchers in China are studying the use of gossypol in a birth control pill for men. Gossypol is a substance found

naturally in cottonseed. More than 10,000 Chinese men have taken gossypol, with as many as 99.4% developing

lower sperm counts. Findings from some of the gossypol studies, however, indicate a decline in potassium levels in

men. Moreover, some studies have shown that after a year of taking gossypol, approximately 80% of men have

resumed normal sperm production, but some men remain azoospermic even after several years. The acceptability

and usefulness of gossypol as a male contraceptive will clearly be influenced by its reversibility. Synthetic

analogues which work either as potent agonists or antagonists of the polypeptide LH-RH, and an injectable pituitary-

suppressing dose of androgen, progestin, or a combination of both are also possible male contraceptives. Findings

from this latter research have not been promising. The article stresses that much of male contraceptive research is

in its early stages. (PubHealth.info Document ID: CONT3T 1578-06)
