Summary[edit]
| Description | Figure 3. Summary of gamete interactions in the hermaphrodite during self-fertilization. (A) Spermatids (in pink) are crowded at the oviduct spermathecal junction by maturing oocytes. (B) Spermatids are pushed into the spermatheca by the first ovulation. (C) Spermatids undergo spermiogenesis to become spermatozoa and compete with each other to fertilize the oocyte. (D) The newly fertilized egg exits the spermatheca and pushes many sperm into the uterus. (E) The displaced sperm crawl from the uterus back into the spermatheca. (F) The second ovulation places an oocyte in the spermatheca and sperm compete to fertilize it. The cell body is pulled behind the pseudopod as spermatozoa crawl forward |
