Final answer:
The functions of the human reproductive system include hormone regulation, gamete production, and fertilization.
Step-by-step explanation:
The functions of the human reproductive system include:
- Hormone regulation: The gonads (testes and ovaries) produce sex hormones that control the development of sex organs before birth, sexual maturation at puberty, and reproduction.
- Gamete production: The gonads also produce gametes (eggs and sperm) through a process called gametogenesis.
- Fertilization: Fertilization is the process where a haploid sperm and a haploid egg combine to form a diploid zygote.
Therefore, the correct answer is d. All of the above.
