What Is the Cystic Duct?

Capsule catheter refers to the catheter that extends from the vulva to the mating sac in female Lepidoptera insects. Mating sacs are also known as mating sacs. They are helminths, molluscs, and insects. The vagina does not directly bind to the fallopian tube. When mating, it is the part of the female genital organ that first receives sperm. In addition, the rear end of the male of the nematode swells to the left and right, forming a wing-like structure that covers the female body during mating. ^[1]
