The serum levels of FSH, LH, and testosterone were determined by radioimmunoassay in 63 men before, during, and after maximal and submaximal physical short- and long-term exercise (800-n running, climbing, 36-k cross-country skiing). In the 800-meter run, significant elevations of FSH, LH, and testosterone were observed, while in all other field and(More)
Typical possibilities of abnormal development in human oocytes cultured and fertilized in vitro were studied using phase-contrast microscopy. All oocytes were checked three times for maturity, fertilization and embryo development. A total of 180 non-cleaved oocytes and 30 embryos originating from polypronuclear oocytes are described. It is concluded that an(More)
The expression of HLA Ag on polyploid early human embryonic stages, obtained in an in vitro fertilization and embryo transfer program, was investigated by indirect immunofluorescence tests using a panel of mAb. Neither HLA class I Ag, beta 2-microglobulin, nor HLA class II molecules could be detected on blastomers. The zona pellucida also lacked these Ag,(More)
In a long-term follow-up study we compared preoperative testicular position, age at orchiopexy, and morphology of testicular biopsies investigated at orchiopexy to sperm analysis results, testicular volume, and serum follicle-stimulating hormone and luteinizing hormone levels at follow-up in 46 men with a history of surgical correction of cryptorchidism in(More)
30 patients with normogonadotrophic oligozoospermia from 1-20 mill/ml (group A) and 30 men with a sperm density from 210-40,0 mill/ml (group B) from the andrologic laboratory of the University Clinic for Gynecology and Obstetrics, Graz, Austria were treated with a 120 mg testosteron-undecanoate per os for 100 days. One randomized half of the patients(More)
Human spermatozoa from 87 donors with normal or pathologic semen specimen were examined for the expression of HLA-class I and class II antigens as well as beta 2-microglobulin (beta 2m) using a panel of monoclonal antibodies in an indirect immunofluorescence test. The results make it very unlikely that HLA-class I and class II molecules as well as beta 2m(More)
The development of a portable electronic gestation calculator enables the obstetrician for the first time to recall all relevant data for his daily routine work from an electronic memory. This is useful not only for the calculation of the duration of pregnancies or the determination of delivery data, but also includes all relevant information from(More)

Zusammenfassend belegen diese Ergebnisse erstmals die Existenz von OMI beim Kaninchen, zeigen, dab eine gonadotropininduzierte Stimulation der in vitro Luteinisation von Granulosazellen zu einer Verminderung der OMI-Produktion bzw.
