45. Which two of the above promote increased uterine contractions and shedding of the fetus during labor?

Answer 1

1) Answer is Correct

The path by which sperm travel are seminiferous tubule, epididymis , vas deferens , seminal vesicle , prostate gland, bulbourethral gland , spongy urethra

2) corpus luteum is not the part of the pe-nis . it is the part of female reproductive system

3) interstitial ( leydig) cells secrete testosterone . These are found inside the seminiferous tubules

4) seminal vesicle supply most of the fluid in the semen . It contributes 60% of the semen
