Spermatophore

A sperm-containing package transferred from a male to a female during mating in many animals. It may also provide nutrients or protect sperm during transfer.

Spermatogenesis: The process by which germ cells develop into sperm cells. Spermatophores carry sperm produced through this process.
Sperm: The male reproductive cell that can fertilize an egg. Sperm are the essential contents that distinguish a spermatophore.
Cephalopod reproduction: Reproductive processes in octopuses, squids, cuttlefish, and their relatives. Many male cephalopods transfer spermatophores, sometimes using a specialized arm.
Artificial insemination: The deliberate introduction of sperm into a female reproductive tract to achieve fertilization. Handling spermatophores can enable controlled insemination in animal breeding and research.
Sperm storage: The retention of sperm within a reproductive tract or specialized organ before fertilization. Females may store sperm received in a spermatophore for later fertilization.
Semen: A fluid containing sperm and secretions from male reproductive glands. Semen is a fluid mixture, whereas a spermatophore is a transferred package.
Salamander reproduction: Reproductive processes in salamanders, including courtship and sperm transfer. Many salamanders transfer a spermatophore that the female picks up with her cloaca.
Aquaculture: The farming of aquatic organisms, including fish, shellfish, and algae. Spermatophore transfer matters to reproduction and breeding in some cultured aquatic animals.
Sperm competition: Competition among sperm from different males to fertilize an egg. Spermatophore design and transfer can affect a male’s success amid rival sperm.
Accessory gland: A reproductive gland that contributes secretions to gametes or mating-related materials. Secretions from accessory glands can form the spermatophore’s casing or matrix.
