Washed human spermatozoa were coincubated at a constant concentration of bradykinin (BK) (10(-8) M) with different concentrations of the bradykinin antagonists Hoe 140, (Thi5,8, D-Phe7)-BK, and D-Arg(Hyp3, D-Phe7)-BK. In the range between 10(-10) and

Vasoactive intestinal polypeptide (VIP) has been suggested to play a role as a nonadrenergic, noncholinergic neurotransmitter or neuromodulator involved in the process of erection. Until now, data about fluctuating concentrations of VIP in corpus cav

Washed human spermatozoa were incubated with different concentrations of bradykinin, des-arg9-bradykinin, and Ile-Ser-bradykinin (T-kinin). Bradykinin significantly increased the total motility of human spermatozoa at a very low concentration (10(-9)

Leucocytospermia has been associated with reduced sperm motility and decreased capacity for sperm-egg interaction. This effect could be mediated through reactive oxygen species (ROS), which, at high concentrations, induce lipid peroxidation and cellu

To date, two different zona binding assays have been described in the literature. Both assays, however, require a large quantity of human zonae which vary immensely in quality. Furthermore, an inverted microscope with micromanipulation equipment is n

alpha-glucosidase is found in human seminal plasma as an acid form, located in accessory glands, and as a neutral form secreted almost exclusively by the epididymis. Quantification of alpha-glucosidase activity is a marker of the secretory function o

The acrosome reaction, which is essential for fertilization, includes fusion and vesiculation of the plasma membrane with the outer acrosomal membrane of spermatozoa, thereby releasing the acrosomal content. Determination of the ability of spermatozo

Sperm functional tests as an addition to semen analysis have been used to study the fertilization ability of spermatozoa. Besides the usual variability of the seminal analysis an individual variability in the results of functional tests has been rece

Peritubular cells, Sertoli cells, and germ cells of the seminiferous tubule synthesize and secrete several proteases and protease inhibitors. Experimental evidence suggests that the complex network of proteolytic enzyme activity and their regulation
