We measured FSH, LH, PRL and Testosterone levels in serum and seminal fluid of 100 patients, 30 fertile and 70 infertile. Plasma Testosterone was similar in different groups of patients, while seminal fluid concentrations were higher in plasma as compared to the seminal fluid. Plasma Prolactin did not show any significant variation among the different groups, whereas seminal Prolactin was always found to be higher than that in plasma. The values of plasma FSH were significantly increased in the patients with testicular hypoplasia. Seminal and plasma LH values did not show any significant variation among the different groups.

Vitrification of human spermatozoa without cryoprotectants.

The aim of our study was to investigate the effects of vitrification (cooling rate approximately 10000(C/min) without cryoprotectants on swim-up prepared human spermatozoa in comparison to standard conventional freezing with cryoprotectants. Motility, morphology, rate of viability and acrosome reaction of spermatozoa were evaluated. The described method of cryopreservation of human spermatozoa by direct plunging into liquid nitrogen slush without cryoprotectants was effective and could be recommended for routine IVF.
