- sperm release defective
Any variation in the initial movement of sperm through the vas deferens, exiting the cloaca, compared to control.
- sperm transfer initiation defective
Any defect in the movement of sperm out of the seminal vesicle and into the vas deferens following tonic insertion of spicules into the mating partner compared to control.
- sperm transfer continuation defective
Any variation in the continued movement of sperm through the vas deferens, exiting the cloaca, compared to control. In C. elegans, when all sperm that exit the seminal vesicle have been released, the spicules retract into the male.
- proctodeum morphology variant
Animals exhibit variations in the structure and organization of the chamber in the male tail that extends from the termination of four canals (vas deferens, gut, and left and right spicule channels) to just before the cloaca, from that observed in control animals.
- proctodeum development variant
Any variation in the process whose specific outcome is the progression of the male proctodeum over time, from its formation to the mature structure, compared to control. The union of the vas deferens and the intestine give rise to the proctodeum which contains copulatory spicules.
- male somatic gonad development variant
Any variation in the progression of the components of the male gonad that are separate from the germline proper over time, from its formation to its mature structure compared to control. In C. elegans, the male somatic gonad consists of three tissues: distal tip cells (DTCs), the seminal vesicle, and the vas deferens (Wormatlas).
