I found the following information at Grateful Med . I didn't find any "statistics" about this. If you find information please forward it to me. Thanks.
TITLE: Morphology of rabbit ovaries after sterilization by uterus horn coagulation or section.
AUTHORS: Riedel HH; Lehmann-Willenbrock E

ABSTRACT: Tubal sterilization of women may lead to menstrual cycle changes and climacteric complaints. Interference with ovarian metabolism, caused by impaired vascular and/or neural supply of the ovaries is held responsible for this. To obtain a histopathologic equivalent of these ovarian alterations in an animal model, we coagulated resp. cut the uterus horns of 316 white New Zealand rabbits by pelviscopy resp. by laparatomy. The pelviscopic method used was endocoagulation acc. to Semm in 80 cases, monopolar high frequency coagulation in 94 cases, and bipolar high frequency coagulation in 109 cases. The uterus horns of 23 rabbits were cut with a CO2-laser by laparotomy, a control group consisted of 10 animals. After 1, 2, 4, 8 or 12 weeks, the rabbits' ovaries were exstirpated by laparotomy and examined morphologically. Results: The increase of the average ovary diameter as well as the decrease of tertiary follicle numbers per ovary were significant by analysis of variance; however, a dependence on the operation method used could not be detected.
TITLE: Attempted transcervical occlusion of the fallopian tube with the Nd:YAG laser.

ABSTRACT: A prospective multi-center trial was initiated to test the efficacy and safety of transcervical occlusion of the fallopian tube with the Nd:YAG laser. A
multi-center approach was deemed necessary because of the large sample size required to test adequately the effectiveness of sterilization procedures. However,
efforts to continue the study as designed were abandoned because, of the 17 subjects completing the study, only four (24%) had bilateral tubal occlusion at the site
of laser treatment. We conclude that the hysteroscopic method, as tested, is inadequate to provide permanent sterilization. Modification of the technique or
alterations in patient preparation may improve the outcome.

CPTwomen members have testified in front of the IL and CA Court, the IL Gov. Task Force, the Sunset Review Committee, (Senator Liz Figueroa), NOW, and more. What occurred has been made a matter of public record. The CPTwomen are making public the issues which millions of other women have faced in silence. Issues such as women are not informed at the time of their tubal ligation that there is a risk of hormonal imbalance occurring. For the CPTwomen to continue its mission to move this issue to the forefront of government, we must ask for a small contribution/subscription fee from all those who wish to communicate with us and participate at the Coalition's Bulletin Board
