Males of inbred strains were orally given lead acetate water solution during 150 days. Changes were found in the structure of the seminiterous tubules and in spermatozoa. The pathological changes in Leydig cells brought about a decline in levels of androgens.

Improvements in the single photon counting method have made it possible to measure total emission intensity to monitor its kinetics and to make measurements (using cut-off filters) of the spectral distribution of electromagnetic radiation emitted from spermatozoa of three farm animals species. The association between peroxidation processes in cell membranes and the accompanying photon emission and sperm viability, sperm motility and metabolic processes was identified and further explored. The application part of the studies concerned the effect of stress factors on bull, ram and boar spermatozoa and the possibility of using ultraweak luminescence as a new biophysical method for evaluation of semen biological value. The obtained results indicate that measurements of ultraweak luminescence can prove useful for solving problems related to the evaluation, conservation and use of farm animal semen.
