Micro-Dissection sperm retrieval (TESE)

Mr Minhas has performed a large number of micro-dissection sperm retrievals and has recently published his data in European Urology 2010 and The British Journal of Urology, International. His overall sperm retrieval rates in men with non-obstructed azoospermia are in the region of approximately 50%.  This data is summarised in the table below

Series	n	Overall SR (%)	SCOS SR (%)	MA SR (%)	Hypospermatogenesis SR (%)
Minhas	89	49.4	41.2	26.7	82.6
Okada 2002	74	44.6	33.9	75	100
Colpi 2009	28	48.3	27.5	85.7	100
Ramasamy 2005	460	57	41	44	81

This technique is based upon that described by Schlegel in New York.  Under a general anaesthetic an incision is made on the scrotum and both testes are delivered and each testis has an incision made transversely.  Under the microscope, any tubules which contain sperm appear to be more dilated and opaque.  It is these tubules which are given to the embryologists at the time of the micro-dissection. 

Mr Minhas is an accomplished micro-Surgeon and currently data seems to indicate that the micro-dissection sperm retrieval technique is the optimum technique in terms of sperm retrieval rates, and also reducing post-operative complications.

Before any patients undergo micro-dissection sperm retrieval they will undergo full evaluation with genetic tests and hormone profile.
