Seventy-two Large White x Landrace pigs born in Feb-Mar, May-Jun, Aug-Sep and Nov-Dec of 1975 through 1976 were slaughtered 1 to 9 months postpartum to study the effects of age, season of birth and body weight on the male reproductive organ weights. Age had highly significant (P/0. 001) effect on body and organ weights. Season of birth had highly significant effect on body weight (P/0.001) but not on organ weight. Positive quadratic regressions existed between age and body weight, age and epididymal weight and, age and vesicular gland weight. The weight of the testes and bulbourethral glands demonstrated cubic regressions. Weight of organs relative to body weight increased with age. Allometric regressions (Log Y=Log a+b Log X) between body and organ weights were positive and highly significant (P/0.001)
