We all know that men and women are different from each other. And many of those differences stem from our biology. Physically and mentally, the males and females are different. Females are more emotional and express the great intensity of emotion when compared to males. Females have puberty changes about two years earlier to males. While fertility in females decreases as they age, particularly after 35 years and it ends with menopause, males are fertile even in their old age.

Difference between male and female:

Male –

  • Chromosomal sex: XY chromosome.
  • Gonadal sex: Testes.
  • Reproductive Organs: Primary reproductive organs in the testes. Others: epididymis, vas deference, seminal vesicles, ejaculatory duct, and penis. Accessory: Prostate, bulbourethral gland. There are also spermatic cord and a scrotum.
  • Cycle in Reproductive life:
  • Secondary sexual character: Different from a female.
  • Gametogenesis: Spermatogenesis begins at puberty.
  • Gonadotropin secretion: Noncyclic secretion in male reproductive life.
  • Sex hormone: From testes testosterone, dihydrotestosterone, androstenedione – collectively called androgen.

Female

  • Chromosomal sex: XX chromosome.
  • Gonadal sex:
  • Reproductive Organs: the Primary reproductive organ in the ovary. Others, uterine tubes uterus, vagina. External – The mons pubis, labia majors, labia majora, bulb of vestibular glands.
  • Cycle in Reproductive life: Shows cyclical changes that regarded as periodic preparation for fertilization and pregnancy.
  • Secondary sexual character: Different from the male.
  • Gametogenesis: Ogenesis begins in intrauterine life. After birth, no oocyte is formed.
  • Gonadotropin secretion: Cyclical gonadotropin secretion.
  • Sex hormone: From Anterior pituitary, FSH and LH. From ovary: Estrogen, progesterone, Relaxin, inhibin.
