Reversal of vasectomy.

Vasovasostomy to reverse a previous vasectomy for sterilization was attempted for 27 men, the procedure being technically impossible in only one case. A testicular biopsy was performed at the time of operation and a number were investigated for cell-mediated immunity to sperm and for the presence of circulating sperm-agglutinating and cytotoxic antibodies. The first 17 cases have been studied and of these there have been 11 pregnancies, ten of which have already come to term with the birth of normal infants, including one set of twins. Of the rest, two are known to have oligozoospermia and four have been lost to follow-up, although two of them were euspermic when last examined. In spite of these encouraging results, it is considered that there are no grounds for alterning the present basis of vasectomy counseling which is that the operation is likely to be irreversible.

Sudies in simpler tubocclusion methods.

This report reviews animal and human studies undertaken to develop simpler, safer, and more acceptable methods of female sterilization. Animal studies revealed inadequate prevention of pregnancy by tubocclusive methods from within the uterus, and the laparoscopic route was chosen. A series of clips were evaluated, and a clip was designed which would have a spring load, be wide enough to cause true tissue necrosis, have a firm grip on the tube to prevent dislodgement, and have a smooth external surface. Extensive human trials of the clip and applicator have resulted in over 1,000 patients with clips applied by 27 physicians in 10 centers throughout the world. Six pregnancies appear to have been due so far to application onto structures other than the isthmic portion of the tube. Complications due to the clip itself appear to be minimal, and the feasibility of performing this operation under local anesthesia in a hospital facility other than the operating room is currently under evaluation.

Seminal vesicles as organs of sperm storage.

This study was done to determine whether or not the seminal vesicles store spermatozoa. Half of the nonhuman primates' vesicles had sperm at autopsy as did one of the men dying a traumatic death. Seminal vesicle sperm storage may be the reason for continued spermatozoa in the ejaculates of men after vasectomy.

Increase in diaphragm use in a university population.

A striking increase observed in the demand for the diaphragm method at a contraception clinic for university women was documented by means of a record review and questionnaire. Record reviews completed at the conclusion of each semester from December 1973 to December 1976 showed a statistically significant increase in diaphragm acceptors. In the fall semester of 1976, diaphragm acceptors (49% of 151 patients) surpassed pill acceptors (46%). Data from 123 questionnaires revealed that concern for pill and IUD side effects was the primary reason for diaphragm choice. The study numbers are small, but a definite trend is evident. These educated young women may be forerunners, and an increase in diagphragm use in the general population may be seen in the near future.

[Surgical procedures for sterilization of the women: certainty--complications (author's transl)].

The time (interval, postpartum, postabortum), location (uterus, mucus membrane of the oviducts, tubes), access (transcervical, transvaginal, trans-abdominal) and the actual method of sterilization for the women (surgical, electric, thermic, mechanical) can be differentiated and combined with each other in various ways. Today the usual procedure is sterilization by partial resection of the oviducts performed laparoscopically in the interval via electrocoagulation and surgically after delivery via periumbilical minilaparotomy. Laparoscopic sterilization via electrocoagulation has a rate of failure of about 1:1,000 and the mortality rate is less than 1:10,000. The most frequent complications are: hemorrhages due to injury of the larger vessels and burns in the intestine caused by the electric current. For this reason, conventional (:unipolar") electrocoagulation should be replaced by the so-called bipolar coagulation or other newer methods which avoid these complications. On the basis of the current literature, no definitive statements can be made regarding the reliability of the newer methods (silastic ring, plastic clips, thermocoagulation). An additional, although up until now purely hypothetic, advantage of the newer methods is the possibility of reversibility. With conventional electrocoagulation, the rate of reversilbility is very low. Additional alternatives are also culdotomy and minilaparotomy in the interval with the assistance of a uterus elevator. Both ways of access may be combined with various methods of sterilization. The pros and cons of the hysterectomy as a method of sterilization are still being discussed. Occasional late sequelae of sterilization such as menstrual disorders, pain and, particularly, problems related to sexual intercourse have only recently come to light. They have not yet been adequately investigated.

[Experience with the tupla-clip for tubal sterilization by laparoscopy (author's transl)].

For the last 18 months a plastic clip made of polyoxymethylene was used for tubal sterilization by laparoscopy. The clip was used in 140 cases. This report reviews 106 cases. One pregnancy occurred early in this series. There were no other complications. The advantages of the method are the short operating time and the elimination of intra-abdominal damage by heat. Reversibility of the method has not yet been assessed.
