In this article, we report a case of pregnancy obtained in an infertile couple diagnosed with severe male factor infertility. The couple attended for fertility examination reporting a history of 10 years of infertility. The cause of infertility was obstructive azoospermia. The treatment consists of in vitro fertilization (IVF). The ovarian stimulation of female patient was done with antagonist ...

Leiomyomata of the urinary and male genital tract are extremely rare. They have been reported throughout the genitourinary male tract and the most common localization is the renal capsule. However, leiomyomas of the epididimis, spermatic cord, tunica albuginea and testis have been reported. We report diagnostic confirmation of a paratesticular leiomyoma in an azoospermic patient undergoing a te...

As tecnologias digitais cada vez mais fazem parte do nosso cotidiano, estando presentes em todos os lugares. As abordagens tradicionais de design faziam sentido quando a computação era direcionada e centrada em atividades bem específicas. As bases que designers antes seguiam para direcionar seus esforços tinham por referência os conceitos de usabilidade e acessibilidade. Mais recentemente, esse...

Varicoceles are an abnormal dilation of the pampiniform plexus of veins within the scrotum. Varicoceles are highly prevalent and can result in a myriad of deleterious effects on male reproduction. Numerous therapeutic options are available for correcting varicoceles, including surgical varicocelectomy radiographic venous embolization. The current literature is reviewed in an effort to answer th...

This finding has caused great concern with round spermatid enthusiasts. A major complaint is that “one should not restrict the label of round spermatid only to those cells in which an acrosomal vesicle is visible” (p. 2977) (4). However, our observation is based not only on phase-contrast evaluation of TESE microdroplets but also on detailed stained histology of many hundreds of testis specimen...

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...

Different surgical methods such as PESA, MESA, TESA, TESE and micro-TESE have been developed to retrieve spermatozoa from either the epididymis or the testis according to the type of azoospermia, i.e., obstructive or non-obstructive. Laboratory techniques are used to remove contaminants, cellular debris, and red blood cells following collection of the epididymal fluid or testicular tissue. Surg...

The purpose of this study was to determine the relationships between monitors of spermatogenesis and predictors of the intracytoplasmic sperm injection (ICSI) outcome in patients with non-obstructive azoospermia (NOA) undergoing testicular sperm extraction (TESE). Seventy-nine patients with NOA (mean age: 43.6±5.2 years), each of whom yielded (97 000±3040) spermatozoa with conventional TESE, we...

We performed this meta-analysis to evaluate the predictive value of different parameters in the sperm retrieval rate (SRR) of microdissection testicular sperm extraction (TESE) in patients with nonobstructive azoospermia (NOA). All relevant studies were searched in PubMed, Web of Science, EMBASE, Cochrane Library, and EBSCO. We chose three parameters to perform the meta-analysis: follicle-stimu...
