The author illustrates various techniques to be applied in preparation for diagnostic and therapeutic procedures for sterility, such as perflation, hysterosalpingography, endometrial biopsy, culdoscopy and laparotomy.

The sex-ratio was established on the basis of the fertility index (F.I.), i.e. the total number of forwards motile and morphological normal spermatozoa in ejaculate. It was stated that the fecundation of a boy needed a higher F.I. The age of the father was not interesting. The F.I. was lower after hormonal treatment, this means: a higher fertilizing capacity on the basis of the treatment. This fact explains, why it is possible to fecundize with lower F.I.

The first four cases of oviduct transplantation are described. In the first case, it consisted in the substitution of an oviduct that could not be recanalized after previous sterilization; two further patients had undergone salpingectomy for ectopic pregnancy, and one had been salpingectiomized for salpingitis. Donor oviducts preserved in liquid nitrogen at--196 degrees C were used as grafts. Rejection was prevented by countersensitization according to Theurer, also a first instance of the use of this method to be recorded in the literature.

There is an ever-present possibility that the children or husband of a sterilized woman may die. In the latter case, and after remarriage, she and her new husband may want children of their own, which presents difficulties, as the low success rate of reconstructive surgery in the sterilised woman is well known. A case history is presented of the first sterilized woman to undergo Fallopian tube transplantation.

The author describes the diagnostic possibilities of plate thermography according to Tricoire in the area of the male external genitalia. This technique enables early detection of tumors and varicosities. The application of plate thermography is recommended for diagnosis in urology and andrology.
