Abstract:
OBJECTIVESTo investigate possible abnormalities of the sperm neck in eight infertile painters observed by transmission electron microscope.
METHODSSpermatozoa from 8 infertile painters (21-32 years old) were observed by transmission electron microscope.
RESULTSThe abnormalities of the connecting piece could be divided into 6 types, among which the anomaly of the connecting piece concomitant with a true nuclemalamic condition was the most serious.
CONCLUSIONSThe abnormalities may be related to expression obstacles of nuclear genome and mitochondrial genome, and to anomalous cellular signal transduction during spermiogenesis as well.
