Abstract

Purpose

To explore sperm chromosomal aneuploidy, sperm membrane and DNA integrity in infertile patients with anejaculation.

Methods

Semen samples were collected from 18 infertile men with spinal cord injury (SCI) by penile vibratory stimulation (PVS) and from 14 psychogenic anejaculation (PA) patients by percutaneous vasal sperm aspiration (PVSA). These semen samples as well as samples from 16 donors were analyzed using the hypo-osmotic swelling (HOS) test, the sperm chromatin dispersion (SCD) test and multi-color fluorescence in situ hybridization (FISH) with probes specific for chromosomes 13, 18, 21, X and Y.

Results

There were significant differences in the percentages of motile sperm, normal morphologic sperm and sperm DNA fragmentation between the infertile men with SCI and the control group (P < 0.05 and P < 0.01). The sperm motility was significantly greater in the PA-PVSA group than in the SCI-PVS group (P < 0.01). The number of round cells per mL of semen obtained from the 18 SCI patients by PVS was between 1 and 8 million. The rate of sperm DNA fragmentation in the SCI-PVS group was higher than that of the PA-PVSA group (P < 0.05). The aneuploidy rates for the SCI patients were 2.4-fold higher for chromosomes 13, 18 and 21 and 2.2-fold higher for chromosomes X and Y than for patients in the control group (P < 0.0001).

Conclusions

The semen quality is poorer, sperm DNA fragmentation and sperm chromosomal aneuploidies are seen at a higher rate for SCI patients compared to healthy, fertile and normospermic men. Whether the difference in yield is due to increased scrotal temperature, genitourinary infection, or other reasons requires further study.

Ambulantisierung: Erste Erfahrungen mit dem Hybrid-DRG

02.05.2024 DCK 2024 Kongressbericht

Die Hybrid-DRG-Verordnung soll dazu führen, dass mehr chirurgische Eingriffe ambulant durchgeführt werden, wie es in anderen Ländern schon länger üblich ist. Die gleiche Vergütung im ambulanten und stationären Sektor hatten Niedergelassene schon lange gefordert. Aber die Umsetzung bereitet ihnen doch Kopfzerbrechen.

Frauen mit Belastungsinkontinenz oder Organprolaps sind nach einer Netz-Operation keineswegs beschwerdefrei. Vielmehr scheint die Krankheitslast weiterhin hoch zu sein, sogar höher als von harninkontinenten Frauen, die sich nicht haben operieren lassen.
