Boar sexual activity was analysed based on the libido index and intensity of ejaculation. The libido index was calculated as the ratio between the duration of ejaculation and time of preparation until ejaculation. The intensity of ejaculation was the volume of ejaculate mL secreted in the unit of time min. Impact assessment was carried out by applying the General Linear Model procedure. Libido and intensity of ejaculation varied under the impact of photoperiod and the breed of boars. With the increase in age, the boar libido weakened, while the volume of ejaculate and intensity of ejaculation increased. Boars manifested better libido when the daylight lasted longer than 12 h in both photoperiod intervals. Different from libido, the volume of ejaculate and intensity of ejaculation were highest when the daylight was shorter than 12 h, but only in the decreasing photoperiod interval.
The boar penis contains the penile urethra and is a common passageway for both semen and urine. However, the boar penis when extended is quite long Minimum — 9 inch , Average inch , Maximum 18 inch. When the boar is not sexually stimulated, the muscle is contracted and forms an S-shaped bend in the penis. Once the boar is excited, neural stimulation causes the retractor muscle to relax and the S-bend unfolds, and the penis extends. One unique feature of the boar is the presence of a preputial pouch.

Boar taint is the offensive odor or taste that can be evident during the cooking or eating of pork or pork products derived from non-castrated male pigs once they reach puberty. Skatole may also be detected in gilts , but this is linked with faecal contamination of the skin. Boar taint is caused by the accumulation of two compounds — androstenone and skatole — in the fat of male pigs. Androstenone a male pheromone is produced in the testes as male pigs reach puberty, while skatole a byproduct of intestinal bacteria, or bacterial metabolite of the amino acid tryptophan is produced in both male and female pigs. However levels are much higher in intact boars because testicular steroids inhibit its breakdown by the liver.
