Testicular sperm extraction by Trucut needle and milking of seminiferous tubules: A technique with high yield and patient acceptability


, : Testicular sperm extraction by Trucut needle and milking of seminiferous tubules: A technique with high yield and patient acceptability. Fertility & Sterility 74(2): 380-383, August

Objective: To assess the sperm yield and patient acceptability of Trucut needle testicular biopsy followed by seminiferous tubule milking. Design: Prospective case analysis. Setting: The Regional Fertility Center, Royal Maternity Hospital, Belfast, Northern Ireland, United Kingdom. Patient(s): Forty-one males with obstructive azoospermia (normal testicular volume and FSH and LH levels). Intervention(s): Trucut needle testicular biopsies under local anesthetic with milking of the seminiferous tubules. Main Outcome Measure(s): Quantitation of sperm retrieved per biopsy core and patient follow-up by questionnaire. Result(s): A mean of 105,634 sperm (range, 5,000-427,800) were retrieved, and the mean biopsy weight was 9.17 mg. Twenty-six subjects found the biopsy painless and 15 were pain-free after biopsy. Conclusion(s): The Trucut needle can be used in combination with seminiferous tubule milking to obtain large numbers of sperm in men with obstructive azoospermia.

The physiological meaning of the coexpression of adenosine A2A receptors and group I metabotropic glutamate receptors in gamma- aminobutyric acid (GABA)ergic striatal neurons is intriguing. Here we provide in vitro and in vivo evidence for a syner...
