Human Sexual Reproduction: Male and Female Roles

  • Daughter cells are born in humans, similar to parents but without beans and with two parents, one male and one female.
  • Human reproduction is sexual, involving male and female parents.
  • Reproduction involves parental contribution from both male and female parents.
  • Male and female symbols represent parents in reproduction.
  • Sexual dimorphism in humans allows for the recognition of male and female sexes based on visible features like facial hair and breast development.
  • Sexual dimorphism aids in identifying male and female cockroaches.
  • Sexual reproduction events include gamete formation, insemination, fertilization, and blastocyst formation.
  • Fertilization occurs when male and female gametes fuse to form a zygote.
  • Implantation follows fertilization, leading to gestation and organ development in the female body.
  • The male reproductive system includes primary sex organs like the testes, which descend from the abdomen to the scrotum before birth for sperm production.

"Understanding Castration: Testicular Anatomy and Function"

  • Surgical removal of testicles is known as castration.
  • Castration involves the longitudinal section of the testes.
  • Each testicular lobe contains 250 to 300 testicular lobes.
  • Seminiferous tubules are present inside the testicular lobes.
  • From each seminiferous tubule, a duct emerges to carry sperm.
  • The duct system is crucial for sperm transportation.
  • Proper notes are essential for comprehensive understanding and revision.
  • The testes are oval-shaped, measuring 4 to 5 centimeters in length and 2 to 3 centimeters in width.
  • The testes are surrounded by a layer of connective tissue called tunica albuginea.
  • Spermatogenesis occurs in the seminiferous tubules, where Sertoli cells and nurse cells play vital roles.

45:34

Sperm Formation and Male Reproductive System

  • Sertoli's Sartoli nurse cell is gone, leading to the need to create sperm.
  • The male germ cells, known as spermatogonia, are crucial for sperm formation.
  • Spermatogonia undergo cell division and meiosis to ultimately become sperm.
  • Sertoli cells play a vital role in nourishing and supporting the sperm.
  • Interstitial cells, also known as Leydig cells, are endocrine in nature and produce testosterone.
  • The pathway of sperm formation involves the seminiferous tubules, Vasa Efferentia, and epididymis.
  • The intratesticular system within the testis is where sperm formation occurs.
  • The extra testicular system, including the Vasa Efferentia, aids in transporting sperm out of the body.
  • The seminal vesicles, paired glands, contribute to the production of seminal fluid.
  • The duct of the seminal vesicle merges with the vas deferens to form the ejaculatory duct.

01:02:02

Male Reproductive System: Anatomy and Function

  • The duct containing seminal vesicle secretion is renamed ejaculate duct.
  • The gland found alongside the ejaculate duct is named prostate gland.
  • A paired gland called bulbourethra gland, also known as Cowper's gland, is found below the prostate gland.
  • The secretion from three glands, including fructose and citrate, is mixed with sperm to form semen.
  • The semen passes through the urethra, which is renamed uranogenital duct due to its dual function.
  • The external genitalia of males is referred to as the penis.
  • The urethra is divided into three parts: prostatic urethra, membranous urethra, and spongy urethra.
  • The ejaculatory duct transports sperm from the testis to the urethra.
  • The urethra extends from the urinary bladder through the penis to the external opening called the meatus.
  • The penis consists of three tissues: corpus cavernosa, corpus spongiosum, and the urethra.

Male Reproductive System: Anatomy and Function

  • The front side is considered ventral, while the rear side is dorsal.
  • Corpus cavernosa and spongy tissue are filled with blood during sexual excitement.
  • Blood vessels lead to erection during sexual excitement.
  • The tip of the penis is called glans penis and is covered by retracted foreskin.
  • Smegma is produced by the preputial gland or gland of Tyson.
  • Surgical removal of the foreskin is called circumcision.
  • Three types of glands in the male reproductive system provide nourishment and lubrication.
  • Seminal vesicle contributes 60 to 70% of the total seminal plasma.
  • Prostate gland releases alkaline secretion to neutralize acidity in the environment.
  • Semen is the combination of secretions from three glands and contains 200 to 300 million sperm in 2.5 to 3 ml.
