Sperm contribution clinic

Sperm donation is the provision by a man of his sperm with the intention that it be used in the artificial insemination or other 'fertility treatment' of a woman or women who are not his sexual partners in order that they may become pregnant by him. The man is known as a 'sperm donor' and the sperm he provides is known as 'donor sperm' because the intention is that the man will give up all legal rights to any child produced from his sperm, and will not be the legal father. However conception is achieved, the nature and course of the pregnancy will be the same as one achieved by sexual intercourse, and the sperm donor will be the biological father of every child born from his donations. Sperm donation enables a man to father a child for third-party women, and is therefore, categorized as a form of third party reproduction.

Non-genetic contributions of the sperm nucleus to embryonic development

This study was performed to evaluate and compare threshold sperm parameters and sperm DNA fragmentation index DFI , and further analyzed whether sperm DFI could be predicted from sperm parameters in men with varicocele. A total of semen samples underwent both semen analysis and sperm DNA fragmentation SDF testing in men with varicocele. Sperm parameters were assessed using the World Health Organization guidelines. SDF testing was performed using the Halosperm kit. Sperm parameters and sperm DFI results were compared.

Sperm bank

Human sperm samples are very heterogeneous and include a low amount of truly functional gametes. Distinct strategies have been developed to characterize and isolate this specific subpopulation. In this study we have used fluorescence microscopy and fluorescence-activated cell sorting to determine if mitochondrial function, as assessed using mitochondrial-sensitive probes, could be employed as a criterion to obtain more functional sperm from a given ejaculate.
