Angiotensin II type 2 receptor is expressed in human sperm cells and is involved in sperm motility

Tuesday, March 1, 2016
Angiotensin II type 2 receptor is present in human spermatozoa and is associated with basic sperm parameters, especially motility.

Interferometric phase microscopy for label free morphological evaluation of sperm cells

Monday, June 29, 2015
Sperm imaging is typically performed using label-based bright-field microscopy, which cannot be used for intracytoplasmic sperm injection. Interferometric phase microscopy was used to evaluate sperm cell morphology without labeling.

DNA fragmentation in brighter sperm predicts male fertility independently from age and semen parameters

Thursday, June 4, 2015
Detecting sperm DNA fragmentation by means of TUNEL/PI predicts male fertility status independently from age and semen parameters, providing additional information in routine semen analysis.

Acute epididymitis induces alterations in sperm protein composition

Sunday, June 1, 2014
A single episode of acute epididymitis is associated with significant alterations in sperm protein composition, with several molecules known to be involved in sperm maturation, function, and fertility.

The treatment of hypogonadism in men of reproductive age

Friday, March 1, 2013
Testosterone therapy has a reversible suppression of spermatogenesis. Selective estrogen receptor modulators represent an alternative therapy for men who desire to maintain future potential fertility. Human chorionic gonadotropin therapy may be considered.

Voltage dependent anion channels are a key factor of male fertility

Monday, February 4, 2013
The abnormal regulation of voltage-dependent anion channels (VDACs) negatively affected sperm function. Thus, VDACs may be key regulators of the fertilization ability of spermatozoa.

Autocrine regulation of human sperm motility by the met-enkephalin opioid peptide

Friday, June 8, 2012
A novel role of the opioid system in the regulation of sperm function is demonstrated that shows that both exogenous and endogenous met-enkephalin can modulate sperm motility.

Proteomic approach in the identification of fertility pattern in seminal plasma of fertile men

Thursday, May 31, 2012
We present a proteomic approach to identify a panel of common proteins in fertile men by using the LTQ-Orbitrap mass spectrometer.

Male fertility: psychiatric considerations

Friday, May 25, 2012
Male infertility may be influenced by psychologic stress and psychotropic agents. Available literature is heterogeneous, and further studies are needed to demonstrate the relationship between stress, antidepressants, and male fertility.
