Vasectomy as a male sterilization has become increasingly popular as one of methods of planned parenthood in many countries including Korea. In this presentation the subject of an overview of male sterilization consists of mainly technical aspects of the ordinary vasectomy and vasovasostomy. the principle of vasectomy is same but some many different technics have been reported and utilized. specific differences are found in technics for immobilizing the vas for making the scrotal incision. for treating the cut ends of vasa, and for removing segments of vas Therefore the author discusses some important factors so as to provide complete protection against the passage of sperm without any failure and to improve the chances of later reversibility according to his experiences of over 7000 vasectomies and 200 vasovasostomis. In the part of ordinary vasectomy procedure, various items such as ideal operative level local anesthesia immobilization of the vas skin incision isolation for the vas treatments of the cut ends of vas prevention of hematoma formation disappearance rate of residual sperm immediate sterility technic complication psychological effects and antibodies following vasectomy are reviewed. In the part of vasovasostomy numerous factors such as operative technics splint various factors for the successful operation overall success rates and low pregnancy rates are discussed and compared with the author's series.

A total of 42 vas anastomoses was performed on experimental animals and successful anastomoses were obtained 19 of the cases and the over-all rate of success was approximately 46 per cent. But 13 dogs in total of 21 dogs were found to be patent in at least one side of vas, or about 65 per cent of total dogs were restored their fecundity. Splinting materials used in this comparative study are chromic catgut, stainless steel wire, dermalon and polyethylen tube, and dermalon has been proved as the most excellent splinting material among thembecause it is no figid but plable and makes no tissue reaction in the vas. Successful anastomosis of vas deferent is affected by many factors. Among these, an inadequate splinting material has been considered as the most important causes of failures. But it should seem that minimal dissection of the tied points of vas as satisfactory approximation of the free ends of vas exert very important effect upon the successful anastomosis as the splinting material does. Consecutive four successful anastomosis of human cases are highly satisfactory results and are very encouraging even in a small series of cases of the present study.

About 60,000 men were undergone voluntary sterilization by the 497 designated doctors during the period from 1962 to October 1965 by the government subsidy program. Besides these numbers more than 15,000 private cases were sterilized by private doctors during the period from 1960 to 1964 in Korea. A general comprehension of the sterilization operation for motivation of customers was illustrated. An analysis of the social history and background of the sterilized men were made on the author's private group and the subsidized group. The most common occupation of the private group was commerce and that of the subsidized group was africulture. The duration intervening between marriage and sterilization indicated 13.6 years in the private group and 16.7 years in the subsidized group. An average age of the sterilized men showed 40 and that of their wives 35. An average number of children of the private group showed 4.7 while that of subsidized group indicated 5.3. Sexual drive following the sterilization was not changed in 81 per cent of the private group and in 71 per cent of the subsidized group. Decrease in sexual activity was revealed in 5 per cent of the private group but in 11 per cent of the subsidized group. General health after the sterilization was not changed in 83 per cent of the private group and in 70 per cent of the subsidized group. Decrease in general health was noted in only 6 per cent of the private group but in 11 per cent of the subsidized group. Frequency of sexual intercourse per week of the private group indicated 1.95 times preoperatively and 1.88 times postoperatively whereas that of the subsidized group revealed 2.27 times preoperatively but 1.99 times postoperatively. In regarding the sexual feeling of their wives, more than 87 per cent of the private group showed no change before and after the operation while 71 per cent of the wives of the subsidized group were not changed. Very few wives of the private group complained of some decrease, but 10 per cent of the subsidized group complained decrease. The time lost from work after the sterilization was about 2 days in the private group while about 8 days in the subsidized group. About 93 per cent of the private group were satisfied with the sterilization but 2 per cent of them did not feel happy after the operation. In the subsidized group 88 per cent were satisfied with the operation but 10 per cent were not satisfied. All of the private group and 80 per cent of the subsidized group would recommend the sterilization method to their friends. Untoward effects on sexual drive and general health are found to be higher in the subsidized group than in the private group. These outcomes are partly due to low edcation and low income of the subsidized group compared with the private group and partly due to unsatisfactory operative technique of the designated doctors. Psychological studies by means of MMPI conducted on 20 sterilization neurosis patients and the results were compared with the control nonvasectomized group. The sterilized group had definite psychological instability so that a preoperative psychological interview is found to invariably be necessary to prevent the sterilization neurosis. It is concluded by this preliminary clinical survey of the vasectomized cases through the author's private system and the government subsidy program that the few who told to decrease in sexual capacity and general health were outnumbered by those reporting an increase. The majority of the cases told of no change. The changes noted by a small proportion of patients appeared to be chiefly of psychological origin because there was no physiologic reason why the operation of vasectomy should causes sexual excess or decrease.

An anastomosis of the vas deferens was performed on 17 patients since 1963.Semen specimens were examined repeatedly in 15 cases of the series after periods from 2 to 24 weeks following removal of the splint. The fifteen were found to have viable sperm in their ejaculates but one of these patients subsequently became azoospermic again. Three of the fifteen cases had some degree of deteriorated effects after the previous vasectomy but they were free of the complications following the successful anastomosis of the vas deferens. Operative rechnics were discussed. In this series 2-0 dermalon was used as a splint in 15 cases and stainless steel wire was used in 2 cases. Liothyronine was given to 16 of 17 patients at or before the operation for periods from 1 to 6months. Over-all successful results would indicate about 65 per cent of the cases operated in the literature. The author's small series indicates that more than 90 per cent of the operated cases could be successful in this operative procedure from the cytological point of view.

The development of immuohistochemistry and the application of electron microscopy have revolutionized our understanding of the pathopysiology of pituitart adenoma. The clinical value of functional characterization of pituitary adenoma has been realized. Immunohistochemical stains using polyclonal antibodies to six pituitary hormones (GH, PRL, ACTH, TSH, FSH & LH) were performed to classify the pituitary adenoma and to investigate the relationship between the results of the immunohistochemical study and pared to the serum hormone level. The results are summarized as follows: The Most common clinical type of pituitary adenoma was prolactinoma and the second was nonfunctioning adenoma. However, the most common immunohistological type of pituitary adenoma was null cell adenoma, the second one, lactotrope adenoma and the third one, mixed sommatotrope & lactotrope adenoma. In the clinically nonfunctioning adenoma cases, null cell adenoma were present in 75%; gonadotrope adenoma and corticotrope adenoma were present in 25%, while the serum prolactin level was increased in ten of the twenty cases(50%) of the null cell adenoma. When the serum prolactin level was increased above the 150ng/ml, the tumor cells gave positive reactions in 95.2% of cases immunohistochemically. But in the cases of GH, FSH & LH, the tumor cells gave positive reactions in 100%, 75%, and 66.7%, respectively. In the case of increased serum prolactin level, more than 50% and 30% proportion of tumor cells showed positive reactions in the micro- and macroadenoma, respectively.

Some investigators suggest that the pancreatic proteinase kallikrein plays an important role in the regulation of spermatozoal motility. Particularly, oral kallikrein therapy exerted a favorable effect on Sperm motility in oligozoospermia and asthenozoospermia. We have carried out a similar clinical investigation of the efficacy of kallikrein, taken orally 60 kU per day for 3-9 months, on the quantitative and qualitative motility of spermatozoa in normogonadotropic infertile men. with 15 idiopathic oligozoospermia and 18 idiopathic asthenozoospermia. Number of spermatozoa increased more than double number of basic levels (over 40 x 10(6)/ml) in the 5 patients (33%) and pregnancy occurred in the 3 patients (20%) out of the 15 patients with idiopathic oligozoospermia (less than 20 x 10(6)/ml) after the kallikrein therapy. In these responded 5 patients, the sperm concentration changed from 13.6 x 10(6)/ml to 54.0 x 10(6)/ml, Motility and viability of spermatozoa improved more than 30% in the 5 patients (28%) and pregnancy occurred in the 2patients (11%) out of the 18 patients with idiopathic asthenozoospermia (less than 20% of sperm motility) after the therapy. In these. improved 5 patients, the sperm motility changed from 9.0% to 45.0%. No remarkable side effect was detected.

This study was carried out to investigate the response of interphase Y chromosome to some drugs and toxins by observing the rate of leukocytes showing Y-body in the peripheral blood. The interphase Y chromosomes of blood leukocytes were stained with quinacrine mustard and the animals used were rabbits, rats and guinea pies. Y-bodies of leukocytes were studied in the animals as well as in man. Changes in positive rate of Y-body in leukocytes and total leukocyte count were observed in the rabbits administered with drug or toxin. The results concerning the rate of Y-body were as follows: 1. Y-bodies were present in the blood leukocytes of the animals. However positive rates in mononuclear and polymorphonuclear leukocytes were lower in animals that in man. The positive rate of Y-body was higher in mononuclear leukocytes than in polymorphonuclear leukocytes in the animals as in man. 2. Bacterial toxins such as typhoid, D.P.T. and cholera vaccines and anticancer drugs such as busulfan and endoxan reduced the positive rates of Y-body both in mononuclear leukocytes and in polymorphonuclear leukocytes. 3. Benzene known as bone marrow toxin reduced the positive rate of Y-body in mononuclear leukocytes, but not that in polymorphonuclear leukocytes. Quinine known as general protoplasmic poison reduced the positive rate of Y-body not only in mononuclear leukocytes but also in polymorphonuclear leukocytes. 4. Antibiotics such as tetracycline and chloramphenicol and steroid hormones such as estrogen, testosterone and prednisolone had no effects on the positive rate of Y-body both in mononuclear leukocytes and in polymorphonuclear leukocytes.
