Predictive value of FSH, testicular volume, and histopathological findings for the sperm retrieval rate of microdissection TESE in nonobstructive azoospermia: a meta-analysis.

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-stimulating hormone (FSH), testicular volume, and testicular histopathological findings which included three patterns: hypospermatogenesis (HS), maturation arrest (MA), and Sertoli-cell-only syndrome (SCOS).

[Changes of contractility and relaxation of corpus cavernosum in hyperlipidemic rabbit in vitro].

Objective: To investigate the mechanisms of erectile dysfunction induced by hyperlipidemia through studying the changes of contractility and relaxation of corpus cavernosum in hypercholesterolemic rabbit in vitro.

Methods: New Zealand white rabbits were randomly divided into control and experiment groups. The control group (n = 20) received a regular diet for 8 weeks while the experimental group (n = 20) were fed a 1% cholesterol diet for 8 weeks.

[Differentiation of rat adipose-derived stem cells into smooth-muscle-like cells in vitro].

Objective: To study the feasibility of inducing the differentiation of rat adipose-derived stem cells (ADSCs) into smooth-muscle-like cells in monolayer culture in vitro.

Methods: ADSCs were obtained from the adipose of the inguinal region of the SD rat. A growth curve of the ADSCs was drawn.
