  • Title: Sperm transport and distribution in the mare.
    Author: Parker WG, Sullivan JJ, First NL.
    Journal: J Reprod Fertil Suppl; 1975 Oct; (23):63-6. PubMed ID: 1060855.
    Abstract:
    Fifty mares were inseminated on Days 2, 4, 7, 11 or 17 of the oestrous cycle with spermatozoa from one of three stallions to observe the distribution of the spermatozoa in various parts of the reproductive tract 12 hr later (Days 3, 5, 8, 12 and 18). Only 0-06 to 2-21% of inseminated spermatozoa were recovered from the tract. More (P less than 0-05) spermatozoa were recovered from the cervix and uterus on Day 12 than on Days 3, 5, 8 and 18. The mean number of spermatozoa recovered from either or both oviducts was significantly greater (P less than 0-10) on Days 5 and 8 than on Days 3, 12 and 18. More spermatozoa were recovered from the right than the left oviduct and the number recovered from the oviducts was significantly (P less than 0-05) influenced by the stallion.
