BACKGROUND Sperm motility is the reliable parameter that roles in success of intracytoplasmic sperm injection (ICSI), especially in azoospermia. Selection of appropriate culture duration, temperature and media for enhancing the sperm motility is an important issue in assisted reproduction program. The aim was to evaluate the sperm motion characteristics after culturing of testicular sperm extra...

BACKGROUND Isolation of sperm suitable for ICSI from fresh or frozen-thawed testicular sperm extraction (TESE) can be facilitated by mechanical or enzymatic processing of the samples. METHODS A retrospective multicentre study was initiated to compare these two approaches. Eleven German centres provided data on their TESE cycles performed during the period 1996/1997. Quality of retrieved sperm...

In males with nonobstructive azoospermia, one of the main histopathologic patterns of the testis is Sertoli cell-only syndrome (SCOS), in which no germ cells are present and only Sertoli cells are contained in the seminiferous tubules. There is not any formal treatment for this pathological condition. However, several studies reported the possibility to perform testicular sperm extraction in pa...

Abstract Study question What are predictors of successful sperm retrieval (SRR) with microdissection testicular extraction (mTESE) in men non-obstructive azoospermia (NOA) according to different etiologies? Summary answer Predictors for SRR were patients various etiologies and effects age on idiopathic NOA KS opposite. is known already due spermatogenic dysfunction, accounting about 60 percent ...

Men with congenital absence or bilateral partial aplasia of vas deferens, or those with failed or surgically unreconstructable obstructions or azospermic men with testicular failure or genetic cause can now be treated by using sperm retrieval techniques in conjunction with in vitro fertilization/intra cytoplasmic sperm injection (ICSI/ IVF). These techniques are: Microsurgical epididymal sperm ...

Testicular sperm extraction is a common procedure used to find spermatogenic cells in men with nonobstructive azoospermia. The laboratory processing of biopsied testicular tissues needs to be performed meticulously to acquire a high yield of cells. In this study, the effectiveness of mincing the tissues after testicular biopsy was assessed using histological evaluation, as was the possible adve...

This paper describes an unusual association of aspermia and untreatable, chronic testicular pain in a young man who underwent 14 surgical interventions for an imperforate anus. Physical examination and ultrasonography revealed left epididymal and vas enlargement, normal-sized testes, tubular ectasia of the left rete testis and a small intraprostatic paramedian left cyst. Retrograde ejaculation ...
