[Personal experience with in vitro fertilization and embryo transfer].

The causes of sterility could be better characterized in 49 so called complex laparoscopies with estimation of sperm ascension and extraction of oocytes following hormonal stimulation. Oocytes could be obtained in sterility operations. They have been fertilized and transferred into the tubes, with the result of 2 pregnancies after 49 such procedures. Up to now there is no late pregnancy after 115 in vitro fertilizations and 53 embryo transfer into the uterus.

Oocyte recovery, in vitro insemination, and transfer into the oviduct after its microsurgical repair at a single laparotomy.

A method combining recovery of a preovulatory oocyte, its in vitro insemination, and transfer into the oviduct with tubal microsurgery at a single laparotomy is described. Of four women in whom tubal microsurgery was clinically indicated and the accompanying tubal transfer of an oocyte inseminated in vitro was performed, two became pregnant. It is not clear whether fertilization occurred in vitro or in vivo. One of the pregnancies miscarried in the fifth week after surgery; the other pregnancy continued without any complications. A normal male infant was subsequently delivered at term. The proposed method is discussed as a possible alternative to in vitro fertilization and embryo transfer in some cases of infertility and as a suitable supplemental procedure in some cases in which tubal microsurgery is indicated.

[Diagnosis of the principle cause for sterility in a couple, based on laparoscopic examination].

A complex laparoscopical approach is demonstrated, whereby clinical failure of spermiogenesis, cervical, ovarian and tubal factor of the female sterility can be detected at a single examination. Spermatozoa are aspirated from the abdominal cavity and peritubal regions following sexual intercourse or artificial "ab uxore" insemination (A. I. D.). If spermatozoa are found, the cervical factor can be excluded and the spermatozoal vitality assessed. The surgery is planned at the periovulatory period after priming a patient with clomiphene (Gravosan Spofa) and HCG (Praedyn Spofa). Follicular fluid is aspirated from large preovulatory follicles and search is done for oocytes whose maturational stage is correlated with plasma hormone levels. The examination is completed with chromoperturbation of oviducts. Out of 23 such laparoscopic examinations, the diagnosis was set down in 18 cases and 6 women became pregnant after treatment.
