We assessed the rates of sperm retrieval and intracytoplasmic sperm injection outcomes, including the neonatal profile of infants conceived, in men with testicular failure. Three-hundred and sixty-five men with testicular failure who underwent micro-dissection testicular sperm extraction were included in this study. We compared their outcomes with 40 men with testicular failure who used donor s...

PURPOSE We evaluated the retrieval rates and reproductive outcomes of percutaneous sperm retrieval according to the cause of obstructive azoospermia. MATERIALS AND METHODS We retrospectively studied the records of 146 men with obstructive azoospermia who underwent sperm retrieval for intracytoplasmic sperm injection. Patients were grouped by the cause of obstruction, including 32 with congeni...

Successful sperm retrieval from ejaculates of nonmosaic Klinefelter's syndrome (KS) patients by using semen cytology examination was described in this report. The clinical parameters of KS patients with sperm compared to patients without sperm were described. One hundred and fifty-one patients were proven to suffer from KS by chromosomal analysis using G-banding. Spermatozoa were obtained from ...

Male factor is the sole reason or a component for infertility in 20 and 30% of cases respectively. The management of the disease may be via medical or surgical treatment. The surgical approach is classified as techniques which improves sperm production and delivery in order to achieve spontaneous pregnancy or sperm retrieval techniques prior to assisted reproductive techniques (ART). Varicocele...

Azoospermia in men requires microsurgical reconstruction or a procedure for sperm retrieval with assisted reproduction to allow fertility. While the chance of successful retrieval of sperm in men with obstructive azoospermia approaches >90%, the chances of sperm retrieval in men with non-obstructive azoospermia (NOA) are not as high. Conventional procedures such as fine needle aspiration of the...

Spinal cord injury (SCI) occurs most often in young men at the peak of their reproductive health. The majority of men with SCI cannot father children naturally. Three major complications contribute to infertility in men with SCI: erectile dysfunction, ejaculatory dysfunction, and abnormal semen quality. Erectile dysfunction can be managed by regimens available to the general population, includi...

BACKGROUND Different sperm retrieval procedures can help retrieve sperms that can be used for Intracytoplasmic Sperm Injection (ICSI) in azoospermic men. The objective was to compare the Intracytoplasmic sperm injection outcome, through different sperm retrieval procedures in azoospermic men. METHODS A Retrospective Study was carried out at Islamabad Clinic Serving Infertile Couples from Sept...

Testicular sperm extraction (TESE) was performed on patients with non-obstructive azoospermia using the conventional or microdissection technique. First, conventional TESE was attempted on all patients. If the sperm was retrieved successfully, the TESE procedure was terminated. Microdissection TESE was indicated only for patients for whom the conventional sperm retrieval was unsuccessful. Sperm...

The introduction of the technique of intracytoplasmic sperm injection to achieve fertilization, especially using surgically retrieved testicular or epididymal sperm from men with obstructive or non-obstructive azoospermia, has revolutionized the field of assisted reproduction. The techniques for the retrieval of spermatozoa vary from relatively simple percutaneous sperm aspiration to open excis...
