Explanation:

• Nocturnal emissions (Option A): These are involuntary ejaculations that occur during sleep, often the first form in which boys experience spermache (the first ejaculation).
• Delayed phase preference (Option B): Refers to a circadian rhythm disorder where individuals prefer to sleep and wake up later, not related to spermache.
• Sexual maturity (Option C): A broader concept encompassing physical and emotional development related to sexuality, not the specific form of spermache.
• Secular trend (Option D): Refers to long - term changes in a population (e.g., changes in age of puberty onset over generations), not the form of spermache.

A. Nocturnal emissions
