The correct Answer is:
To answer the question regarding which effects are all influenced by Follicle Stimulating Hormone (FSH), we need to analyze each of the listed effects: 1. **Promotion of sperm production**: FSH plays a crucial role in male reproductive physiology by stimulating the Sertoli cells in the testes, which support sperm production (spermatogenesis). Therefore, this effect is influenced by FSH. 2. **Stimulation of oestrogen production**: In females, FSH stimulates the ovarian follicles to produce oestrogen. Thus, this effect is also influenced by FSH. 3. **Development of corpus luteum**: The corpus luteum is formed after ovulation and is primarily maintained by Luteinizing Hormone (LH), not FSH. Therefore, this effect is not influenced by FSH. 4. **Maturation of Graafian follicle**: FSH is responsible for the growth and maturation of the Graafian follicle in females. Hence, this effect is influenced by FSH. 5. **Stimulation of progesterone production**: Progesterone is primarily produced by the corpus luteum, which is stimulated by LH. Therefore, this effect is not influenced by FSH. Now, we summarize the effects influenced by FSH: - **Effects influenced by FSH**: - Promotion of sperm production - Stimulation of oestrogen production - Maturation of Graafian follicle Thus, the effects that are all influenced by FSH are 1, 2, and 4. ### Final Answer: The effects that are all influenced by FSH are: 1. Promotion of sperm production 2. Stimulation of oestrogen production 4. Maturation of Graafian follicle
