Science

• In sexual reproduction, there would be a union of gametes known as spermatozoa or sperm cells and ova or egg cells.
• Both reproductive systems, male and female, have primary and accessory reproductive organs.
• Primary organs in the male reproductive system are those who produce sex cells, while accessory organs are those who transport the sex cells into different parts of the reproductive system.
• GnRH, LH & FSH, Estradiol, Estradiol are hormones involved in the Mestrual Cycle.
• Hypothalamus, Anterior Pituitary, Ovaries, Follicle, Uterus, Endometrium are topics in the Mestrual Cycle.
• Follicular Phase, Ovulation are phases in the Mestrual Cycle.
• Spermatogenesis is the production of spermatozoa which happens at the seminiferous tubules located inside the testes.
• Copulation is the transfer of sperm to the female reproductive tract during intercourse.
• Testosterone is a male hormone produced at the Leydig cells of the testes.
• The scrotum is a sac of skin that holds the testicles and maintains an optimal temperature for sperm production, a process called thermoregulation.
• The testes or testicles are the sites of spermatogenesis and testosterone production.
• Inside the testes are the seminiferous tubules which help with sperm production.
• Semen is transported from the seminiferous tubules to the rete testis which goes to the epididymis.
• The epididymis is where sperm matures and is stored for several months.
• The vas deferens transports the mature sperm cells to the urethra in preparation for ejaculation.
• The seminal vesicles are yellowish finger shaped structures found slightly posterior and inferior to the bladder that produce fluids that 60% of them comprises of the semen.
• The prostate gland is a chestnut shaped structure enveloping the urethra inferior to the bladder that secretes thin and milky fluid through a series of ducts.
• The bulbourethral gland or Cowper’s gland secretes clear, mucus fluid which neutralizes acidic urine along the urethra and provides natural lubrication for intercourse.
• The urethra transports urine and semen out of the tract.
• The penis is the copulatory organ of the male reproductive system, providing the channel which semen and urine leaves the body.
• During Luteal Phase, Pituitary Hormone Effect involves LH and FSH stimulating growth of a corpus luteum from follicular tissue left behind after ovulation.
• Endometrium lining would increase.
• Arterior pituitary hormone production would go down.
• Progesterone would reach it’s highest production.
• Body Temperature greatly increased.
• GnRH stands for Gonadotropin releasing hormone.
• At Day 13, Lutenizing Hormones has an uphill production.
• Ovulation (Day 14): The release of ova from the follicle.
• Endometrium lining would continuously increase.
• LH stands for Luteinizing Hormone.
• P, P4 stands for Progesterone.
• Estrogen continues to grow in production.
• Ovarian Hormone Effect involves the corpus luteum secreting estradiol and progesterone that blocks GnRH production by the hypothalamus and LH and FSH production by the pituitary and causes the endometrium to further develop.
• Estrogen greatly depletes in production.
• During Ovulation, Pituitary Hormone Effect involves LH and FSH stimulating maturation of one of the growing follicles.
• The Vulva is the external female genitalia which runs from the pubic area downward the rectum, featuring the Labia majora, Labia minora, Clitoris, Urethral opening, Vaginal opening, Vaginal vestibule, and Bartholin’s Gland.
• During Menstruation, Follicular Phase, Pituitary Hormone Effect involves LH and FSH stimulating several follicles to grow.
• Oogenesis is the production of sex cells in the form of ova or egg cells in the ovary.
• High Body Temperature but would go down on the 28th day.
• The Follicular Phase of the Menstrual Cycle continues with the follicle continuing to grow, body temperature remains constant, and there would be a higher production of Lutenizing hormones than Follicle-stimulating hormones.
