Norplant implants
Objective To determine if fertilization occurs unnoticed among Norplant users who are ovulatory. Design Serial blood samples were obtained during 1 month from sexually active Norplant users experiencing regular menstrual bleeding patterns and a control group of noncontracepting women trying to conceive. The sequential blood samples were assayed for the presence of human chorionic gonadotropin (hCG). Setting All samples were obtained from women re…
Prevalence of Contraceptive Use
This article discusses the sources of data for estimates of contraceptive use, including their reliability and validity. Data from sample surveys and from censuses are presented by countries from the 1960s to the present time. Tables on proportions of users by method of contraception for various time periods are included. The relationship between contraceptive use and level of fertility is also shown. Contraceptive use has increased rapidly in mu…

Prevalence of Contraceptive Use in Developing Countries
This chartbook brings together information on the proportion of couples in developing countries currently using contraception by method of contraception used. For conparative purposes data on prevalence of contraceptive use are also presented for a few developed countries. There is an enormous range in the proportion of couples using contraception with many African countries having reported rates near 0 and several developing countries with rates…
The Development of NORPLANT Implants
The NORPLANT contraceptive implant system is long-acting and highly effective. A single visit to the clinic for subdermal placement of implants can provide protection from pregnancy for 5 years or longer. Research and development began in 1966 at the Population Councils laboratories and was completed by the Councils International Committee for Contraception Research (ICCR). The method is a product of international science; research groups in Asia…

Fertility Regulation Technology
The current status of and prospects for contraceptive methods is reviewed. Regulations governing the development, safety, and effectiveness of contraceptive methods are discussed, as well as the nature of the female and male reproductive system. Methods reviewed include coitus interruptus, the condom, spermicidal contraceptive agents, postcoital douching, the vaginal diaphragm, male and female sterilization, the rhythm method, oral contraceptives…

Mortality Risk with Oral Contraceptives
Current status of research on the control of fertility
The last decade has witnessed the introduction of methods of contraception, based for the first time on means other than mechanical blockade of spermatozoa in order to prevent their ascent to the fallopian tube. Oral contraceptives, estrogen and progestin, either in combination tablets or sequentially administered, are inhibitors of ovulation. The effect on ovulation is subsequent to suppression of pituitary gonadotropin release which, in turn, i…
