Sterilization has become the single most prevalent method of family planning on an international scale. It is estimated that approximately 80 million surgical sterilization procedures have been performed since the early 195Os, and the majority of these have been female.' The demand for female sterilization is growing, and there is a clear need for a safe(More)
To determine the safety of transcervical administration of quinacrine pellets as a method of voluntary female sterilization, three noncomparative Phase I clinical trials of the administration of 250 mg quinacrine were carried out in 21 women who were scheduled to undergo hysterectomy 24 h or one month later. Detailed results are presented for one of the(More)
The present study details gross and histologic findings of 79 previously ligated fallopian tubes from 3 groups of patients. Of 20 oviducts removed after documented sterilization failure (group I), 6 revealed a process compatible with endometriosis. Four of nine previously ligated fallopian tubes removed at the Johns Hopkins Hospital (group II) were(More)
Data on 14,700 female sterilization patients were collected by the International Fertility Research Program (IFRP) from 1972 to 1978 and analyzed to determine risk factors associated with the incidence of pregnancy following sterilization. With a case-control approach, it was found that younger patients (less than or equal to 34 years old) and those who did(More)
A randomized clinical trial concerning immediate post-placental insertion (IPPI) of the Delta Lippes Loop, Delta TCu22OC, and TCu22OC was undertaken to assess the effect of the addition of catgut strands on IUD performance. A total of 906 devices were inserted and the subjects followed for 20 months, at which time 14,136 woman-months experience had been(More)
The development of a safe, effective nonsurgical method of female sterilization that can be performed by paramedical personnel remains a high priority. The method should have a blind delivery system and require only one application. Methyl cyanoacrylate and quinacrine hydrochloride are the two most promising chemical agents. Quinacrine has evolved from(More)
The ability of prostacyclin analogue incorporated into a controlled-release suture to prevent postoperative venous thrombosis was investigated. Thirteen rats underwent bilateral transection and anastomosis of the common femoral vein. In each animal, polycaprolactone suture containing 0.25 micrograms/cm of the prostacyclin analogue Iloprost (Schering Ag,(More)
The provision of new technologies of fertility control that are known to be safer, simpler, and more effective may at first result in higher complication rates, particularly if training in the new techniques is inadequate. This was illustrated by analysis of data on several fertility control methods collected by the International Fertility Research Program.(More)
