Protoss have both male and female genders and reproduce sexually. Their reproductive organs are very much analogous to Terrans, with the exception that male reproductive anatomy is internal. Females give birth after a gestation of 12 months.
Protoss are extremely resistant to fatigue and illness and are vulnerable only in extreme conditions. Wounds, fatigue, and poor sanitation combined only, can result in illness.
Although a Protoss's overall life-span is long, Protoss still physically mature in about the same amount of time as humans. While Protoss under 200 rarely have much social standing or rank, they are still physically adults.
