In hazards evaluations, the MCE, from a hypothesized accidental explosion, fire, or toxic chemical agent release (with explosives contribution) is the worst single event that is likely to occur from a given quantity and disposition of ammunition and explosives (AE).
A male organism is the physiological sex which produces sperm. Each spermatozoon can fuse with a larger female gamete, or ovum, in the process of fertilization. A male cannot reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and asexually.
Condoms are a barrier method of contraception. A male condom is a thin sheath (usually made of latex, a type of rubber) that is worn on the penis. A female condom is a polyurethane sheath with a flexible ring at either end.
