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. |

| Recent study findings on macaques reported by Marx et al. suggest that the use of contraceptives containing only |
| progestins, such as Depo-Provera, may increase the likelihood of HIV transmission to women. In the study, 14 of 18 |
| macaques pretreated with progesterone-releasing pellets and then inoculated vaginally with simian |
| immunodeficiency virus (SIV) became infected compared to only 1 of 10 macaques pretreated with placebo pellets |
| and inoculated during the follicular phase of the menstrual cycle. In separate experiments using the same protocol, |
| viral stocks and doses, cycling macaques were exposed to SIV without regard to the phase of their menstrual cycles. |
| Four of 11 animals were infected. The infection rate in the progesterone-pretreated macaques was therefore 2.1 |
| times greater than that of the cycling macaques. The 10 published human studies investigating the relationship |
| between Depo-Provera use and HIV transmission yielded estimates of infection risk in the range 0.44-3.8 for women |
| taking Depo-Provera. Only one risk estimate, however, remained significant after adjusting for confounding factors. |
| Findings from the macaque and human epidemiological studies together suggest that the effect of Depo-Provera use |
| on HIV transmission will be difficult to establish. Bias is an issue. There are no data to suggest that Depo-Provera |
| protects against HIV transmission. As such, all couples at risk of HIV infection and engaging in sexual intercourse |
| need to use condoms consistently and correctly regardless of any other contraceptive they may use. (PubHealth.info |
