Male and Female Reproductive Systems

1
Male and FemaleReproductive Systems

• Humans and other organisms have complex
  reproductive systems that ensure the survival of
  the species.

2
Human Male Reproductive System

• Structure of male reproductive system, sperm and
  sperm production

Associated Hormones
Hormone Sent from Acts on Function
Gonadotrophic Hormone (GnRH) Hypothalamus Pituitary gland Tells pituitary gland to secrete LH and FSH
Follicle Stimulating Hormone (FSH) Pituitary gland Testis Stimulates production of sperm in seminiferous tubuules
Lutenizing Hormone (LH)(ICSH) Pituitary gland Testis Stimulates Leydig cells to produce testosterone
Testosterone Testis Body/ hypothalamus Helps to stimulate sperm production/ secondary sex characteristics and release of GnRH
Inhibitin Sertoli cells Pituitary gland Slows the release of FSH and GnRH

Human Male Reproductive System
Urinary Bladder Seminal Vesicle
Prostate Bulbourethral Gland Epididymis Vas
deferens Testis Scrotum Urethera
5
Human Male Reproductive System

• Urinary bladder collect and store urine for
  excretion.
• Seminal Vesicle add fluid to spermatozoa for
  nourishment (sugar rich)
• Prostate add fluid to spermatozoa (secrete fluid
  that neutralizes acids in the vagina)
• Bulbourethral Gland secrete alkaline fluid to
  neutralize acidic urine in urethra.
• Epididymis tube for storing and maturing
  spermatozoa before being released into the vas
  deferens
• Vas deferens tube leading to urethera in which
  sperm become active.
• Testes tissue in which spermatogenisis takes
  place.
• Urethera tube that leads from the urinary
  bladder to the outside.

6
Sperm

• Male haploid sex cell or gamete
• HAPLOID HALF THE GENETIC COMPLEMENT OF THE
  ORGANISM (23 chromosomes in human male).
• Produced in testes
• Ideal temperature for production is 34 degrees
  Celsius
• must be accompanied by fluids so that the sperm
  may move.

Associated Hormones
Hormone Sent from Acts on Function
Gonadotrophic Hormone (GnRH) Hypothalamus Pituitary gland Tells pituitary gland to secrete LH and FSH
Follicle Stimulating Hormone (FSH) Pituitary gland Ovary Stimullates the development of oocytes and maturation of follicles
Lutenizing Hormone (LH) Pituitary gland Ovary Simulate the migration of follicle in ovary
Estrogen Ovary Body/ uterus Forms secondary sex characteristics/ influence the forming of the endometrium
Proghesterone Ovary uterus Maintains the endometrium
9
Female Reproductive System

• Oviduct/ fallopean tube
• Fimbrae
• Ovary
• Uterus
• Cervix
• Vaginal canal
• Bladder
• Urethra

10
Organs

• Uterus protective structure that is the site of
  implantation and development
• Ovary Structure in which the ova are produced
  and developed into follicles
• Oviduct the tube which is the site of
  fertilization and sends the fertilized follicle
  to the uterus
• Fimbriae structures of oviduct that create
  currents to bring the ova into the oviduct
• Cervix muscular structure that is the entrance
  to the uterus and closes the uterus so that the
  developing fetus is protected
• Vagina the canal that leads the sperm to the
  uterus

11
Ovum

• Female gamete
• Haploid (23 chromosomes in human)
• Developed during embryonic stage
• Matured during puberty
• Menopause when follilces are no longer being
  formed
