Study Notes
Male and Female Gametes
- Gametes are reproductive cells, formed from primordial germ cells
- Spermatogenesis is the process in males; oogenesis is the process in females
- Male gametes are formed in the testes
- Female gametes are formed in the ovaries
- Sperm formation begins at puberty and continues throughout life
- Ovum formation begins in the uterus in utero, and resumes at puberty, continuing until menopause
Sperm Morphology
- A human sperm is 55 microns long
- Head (4 microns): contains a condensed nucleus with 22 autosomes and an X or Y sex chromosome; covered by an acrosomal cap, containing enzymes for fertilization
- Neck: narrow part between the head and middle piece
- Middle piece (6 microns): contains mitochondria, providing energy for sperm motility
- Tail (45 microns): formed of an axial filament; the tail directs sperm movement towards the ovum and helps in fertilization
Ovum Morphology
- The diameter of a mature ovum is approximately 120 microns
- Consists of a nucleus with maternal genetic material (22 autosomes and X chromosome)
- Large cytoplasm (initial source of nutrition for the zygote)
- Zona pellucida: glycoprotein coat; contains sperm receptors (for attraction)
- Corona radiata: outer layer of follicular cells (derived from the ovary)
Fertilization
- Definition: Union of male (sperm) and female (ovum) gametes to form a zygote
- Location: ampulla of the uterine tube
- Mechanism (Steps):
- Sperm capacitation: removal of glycoprotein coat from sperm acrosomal regions (takes about 7 hours)
- Corona radiata penetration: only 300-500 sperms out of 200-300 million will reach the ovum and start corona radiata dispersion
