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. |

| The effects of oral contraceptives on the endometrium. I. Blood vessels. |
| Blaustein A; Shenker L; Post RC |
| International Journal of Fertility. 1968 Oct-Dec;13(4):466-475. |
| 78 endometrial biopsies from 58 patients (ages 21-50 years) taking both sequential and combination oral |
| contraceptives, and 10 extra-uterine tissues were studied for vascular changes. Of the endometria examined, 31.3% |
| revealed endothelial hyperplasia in coiled and basilar arteries as well as sinusoids, and 5.1% were so extensive as |
| to reduce the caliber of the overall lumen. Smooth muscle hyperplasia was evident in 82%, of which 3.4% were |
| considered extensive. Similar changes were observed in the skin, colon, cervix, ovary and breast tissue, suggesting |
| that while end organ response is readily detected, the vascular changes are not wholly confined to the uterus. The |
| incidence was higher in patients on sequential therapy (endothelial hyperplasia in 73%, smooth muscle hyperplasia |
| in 58%) than in those on combination therapy (endothelial hyperplasia in 48%, smooth muscle hyperplasia in 33%). |
| There appeared to be no relationship of incidence to duration of therapy, and lesions did not appear to be |
| progressive. Studies of the endometrium of pregnancy, hyperplasia and polypi revealed similar changes in all |
| conditions, though rarely to the same degree. Oral contraceptives used for long periods of time could result in thick- |
| walled vessels and narrowed lumina; the relationship of such alterations to arteriosclerosis remains to be |
| determined. There is a distinct possibility that endothelial hyperplasia may be related to thromboembolism, since |
| venous channels and sinusoids show endothelial hyperplasia as well as arteries. (PubHealth.info Document ID: |
