This may require planting deeper than 1.5 inches under dry soil conditions. If you must plant deeper than 1.5 inches in order to place the seed into uniform moisture, make sure the variety has an excellent emergence score or long hypocotyl. Also, consider seed size when deciding how deep to plant.
Sperm is made in the testes, but stored in the epididymis, a gland where it is also matured. Sperm from the testes cannot yet move on their own.
The male gonads, or testes, produce sperm within the seminiferous tubules; the sperm are housed here until they are nearly mature, at which point they enter the epidydimis for full maturation. The testes are housed in the scrotum, an external sac that keeps the sperm at a temperature lower than that of the body.
