Study Notes
Overview of Human Reproduction
Human reproduction is the process by which humans produce offspring. It involves the combination of genetic material from two individuals to form a unique offspring.
Male Reproductive System
-
Organs:
- Testes: produce sperm
- Epididymis: store and transport sperm
- Vas deferens: muscular tube that transports sperm
- Urethra: tube that carries sperm and urine out of the body
- Penis: external genital organ
-
Hormones:
- Testosterone: regulates development and maintenance of male reproductive organs
Female Reproductive System
-
Organs:
- Ovaries: produce eggs (oocytes)
- Fallopian tubes: transport eggs from ovaries to uterus
- Uterus: nurtures fertilized egg
- Cervix: lower part of uterus that opens into vagina
- Vagina: muscular canal that connects cervix to outside of body
-
Hormones:
- Estrogen: regulates development and maintenance of female reproductive organs
- Progesterone: prepares uterus for implantation of fertilized egg
Fertilization and Pregnancy
- Fertilization: fusion of sperm and egg to form a zygote
- Implantation: zygote implants in uterus
- Pregnancy: development of fetus from implantation to birth
- Gestation: approximately 40 weeks from fertilization to birth
Menstrual Cycle
-
Phases:
- Menstruation: shedding of uterus lining (endometrium)
- Follicular phase: growth of follicles in ovaries
- Ovulation: release of egg from ovary
- Luteal phase: preparation of uterus for implantation
- Hormonal regulation: estrogen and progesterone regulate menstrual cycle
