The aim of this paper was to measure the concentration of spermatic ATP and acrosin in a group of patients with polyzoospermia, and to compare these values with those found in a group of normozoospermic men. The general characteristics of the semen, the ATP and the acrosin, were measured in a group of 46 men with polyzoospermia, who consulted in our clinic(More)
Prostaglandin (PG) E and 19-OH PGE, now considered to be the most important of the human seminal prostaglandins, were assayed in infertile and normal men. In the 15 volunteers PGE and 19-OH PGE levels were 23-89 microgram/ml, respectively. In the 4 groups of infertile patients in whom either PGE or 19-OH PGE levels were increased or decreased with respect(More)
A single-blind study on the effects of kallikrein in idiopathic oligozoospermia was carried out. 8 of the 16 patients admitted to the trial were treated with kallikrein 100 K.U. t.i.d., the remaining patients received vitamin E 100 mg t.i.d. Treatment lasted 120 days in both groups. Kallikrein led to an increase in sperm concentration, total sperm count and(More)
To further investigate the effectiveness of pentoxifylline (trental) treatment in male infertility, we studied 22 young men (mean age 28.4 years) with "idiopathic" oligo-asthenozoospermia treated for 6 months with the drug (1200 mg daily orally). Sperm concentration and sperm motility were determined before therapy, as well as after 3 and 6 months of(More)
A therapeutic trial based on pharmacologically induced azoospermia followed by the administration of corticosteroids was carried out in 48 patients with infertility due to spermagglutinins. Three types of responses were observed: type A, no modifications in the blood and spermagglutinating (SA) titer (19 cases); type B, disappearance or significant decrease(More)
Vesiculodeferentography (VDG) plays an important role in diagnosing male infertility and staging of prostatic cancer; the techniques of performing the examination are, today, well codified: 1) retrograde, by endoscopic cannulation of ejaculatory ducts; 2) anterograde, by cannulation of the deferent duct surgically prepared at the scrotum. In order to avoid(More)
The aim of the present paper was to study the effect of forced lipid peroxidation upon human spermatozoa and its relation with motility, velocity, linearity and ATP content. Forty-three pools of semen samples were studied one hour after liquefaction. After washing, normal and pathological spermatozoa presented no variations in motility, velocity or(More)
