Study Notes
Male Reproductive System
- Consists of:
- Testes (produce sperm)
- Epididymis (stores sperm)
- Vas deferens (transports sperm)
- Ejaculatory ducts (transport sperm and seminal fluid)
- Urethra (transport sperm and urine)
- Penis (delivers sperm during ejaculation)
Sperm
- Produced in the testes through a process called spermatogenesis
- Consists of:
- Head (contains genetic material)
- Neck (connects head to tail)
- Tail (propels sperm during ejaculation)
- Capacitation: process by which sperm become capable of fertilization
Female Reproductive System
- Consists of:
- Ovaries (produce eggs)
- Fallopian tubes (transport eggs)
- Uterus (supports fetal development)
- Cervix (connects uterus to vagina)
- Vagina (receives sperm during intercourse)
Ova (Eggs)
- Produced in the ovaries through a process called oogenesis
- Released from the ovaries during ovulation
- Fertilization: the process by which a sperm fertilizes an egg
Fertilization and Conception
- Occurs in the fallopian tube
- Resulting zygote undergoes several cell divisions before implanting in the uterus
- Implantation: the process by which the zygote attaches to the uterine lining
Hormonal Regulation
- Hypothalamic-pituitary-gonadal axis:
- Hypothalamus regulates hormone production
- Pituitary gland stimulates hormone production in the gonads (ovaries and testes)
- Key hormones involved in human reproduction:
- Follicle-stimulating hormone (FSH)
- Luteinizing hormone (LH)
- Estrogen
- Progesterone
- Testosterone
Male Reproductive System
- Testes produce sperm through a process called spermatogenesis
- Epididymis stores sperm, and Vas deferens transports them to the ejaculatory ducts
- Ejaculatory ducts combine sperm with seminal fluid, and the urethra transports the mixture
- The penis delivers sperm during ejaculation
Sperm Structure and Function
- Composed of a head, neck, and tail
- Head contains genetic material, neck connects the head to the tail
- Tail propels sperm during ejaculation
- Sperm undergo capacitation to become capable of fertilization
Female Reproductive System
- Ovaries produce eggs through a process called oogenesis
- Fallopian tubes transport eggs to the uterus
- Uterus supports fetal development, and the cervix connects the uterus to the vagina
- Vagina receives sperm during intercourse
Ova (Eggs)
- Produced in the ovaries through oogenesis
- Released from the ovaries during ovulation
- Fertilization occurs when a sperm fertilizes an egg
Fertilization and Conception
- Fertilization occurs in the fallopian tube
- The resulting zygote undergoes several cell divisions before implanting in the uterus
- Implantation is the process by which the zygote attaches to the uterine lining
Hormonal Regulation of Human Reproduction
- The hypothalamic-pituitary-gonadal axis regulates hormone production
- Hypothalamus regulates hormone production, and the pituitary gland stimulates hormone production in the gonads (ovaries and testes)
- Key hormones involved in human reproduction include FSH, LH, estrogen, progesterone, and testosterone
