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

80% of the world's contraceptive users are women. This gender-based usage has occurred due to the emphasis of

family planning programs and contraception research on female methods. Even if men desired to take responsibility

for contraception, only the condom and vasectomy are available and have a reasonable assurance of protection. The

Population Council has been researching male contraception through its Center for Biomedical Research. An oral

contraceptive derived from gossypol, a cottonseed plant pigment, is being tested after successful clinical trials were

performed in China during the 1970s. Also being investigated are male hormonal methods that regulate sperm

production while protecting against loss of potency, loss of libido, and changes in secondary sex characteristics. A

hormonal implant, effective for one year, has been in Phase I clinical trials since 1993. A small Phase I clinical trial

is in process for a vaccine/implant for men that is effective for one year. Testing with injectables for men has

suggested that different hormonal mixes could increase cardiovascular risk for men and exacerbate prostate cancer.

Research has focused on new materials for condoms. Kraton-type materials are made from block copolymers and

polyurethanes, and these condoms have shown some promise. The advantages of these products are that they are

allergen-free, less susceptible to oxidation, and can be of thinner construction, which would increase sensitivity and

acceptability. The percutaneous chemical method of no-scalpel vasectomy has been studied as a means of

blocking passage of sperm in the vas deferens. In China and India, injections with liquid silicone, polyurethane,

neem-oil, and n-butyl-cyanoacrylate mixed with phenol are being studied. Zinc injections that cause the epididymis to

atrophy are being tested on animals in the US. Lasers and fiber cautery are other methods under investigation.

Increased funding is essential for these and other research efforts. (PubHealth.info Document ID: CONT2T 3025-06)
