“…In other mammals the uterus responds by increasing uterine tone (and intraluminal pressure) for a prolonged period in the form of one long contraction. Cows (VanDemark & Hays, 1952), sheep (van derWeyden, 1983, dogs (Evans, 1933) and some primates (Goldfoot et al, 1980) show this pattern. In every case yet reported, the uterus responds to mating.…”

“…Mating-associated stimulation is known to alter the rate and strength of uterine contractions in several species (e.g. cows: VanDemark & Moeller, 1951;VanDemark & Hays, 1952, 1954women: Masters & Johnson, 1966;rabbits: Krehbiel & Carstens, 1939;macaques: Goldfoot, Westerborg-vanLoon, Groeneveld & Slob, 1980). Moreover, without stimulation that induces uterine contractions, the females of some species cannot achieve pregnancy (e.g.…”

“…Neither the class of ewe nor the management imposed at mating appeared to affect the mean numbers of spermatozoa present in the cervix at any time after coitus. In dairy cattle, uterine activity is increased for a short period after coitus but fear or injection of adrenaline inhibit uterine motility (Van Demark and Hays 1952;Hays and Van Demark 1953). In addition.…”

SummaryObservations were made on the distribution of spermatozoa in the genital tract of the ewe at 15 min, and at 4, 24, and 48 hr after coitus. A total of 60 animals was used. The number of spermatozoa in t,he cervix wa.s highest at 15 min and in the uterus the maximum number was recorded at 24 hr. Stress decreased the number of spermatozoa present in the fallopian tubes at 15 min after coitus but did not influence the transport of spermatozoa into the cervix, the distribution of spermatozoa within the genital tract at 4, 24, and 48 hI', the number of spermatozoa on the zona pellucida of recovered eggs, or the proportion of eggs fertilized.Results indica.te that slow passage of spermatozoa. from the cervix to the fallopian tube of the ewo may eontinue for many hours inespective of the occurrence or failure of rapid transport.

“…Rapid transport of spermatozoa appears to be a result of strong uterine contractions such as are induced by mating (Reynolds 1930;Millar 1952;Van Demark and Hays 1952) or by mechanical stimulation of the cervix or the external genitalia (Beshlebnov 1938;Krehbiel and Carstens 1939). During this phase of transport, spermatozoan motility probably contributes little toward the passage of spermatozoa through the genital tract of the ewe since inert particles were found in the fallopian tubes of some ewes within 15 min after suspensions of such particles were deposited in the anterior vagina (Mattner and Braden 1963).…”

“…During this phase of transport, spermatozoan motility probably contributes little toward the passage of spermatozoa through the genital tract of the ewe since inert particles were found in the fallopian tubes of some ewes within 15 min after suspensions of such particles were deposited in the anterior vagina (Mattner and Braden 1963). However, the response of the uterus to the stimulation of mating or manipulation of the cervix is only transient and uterine activity returns to the prestimulation level within a few minutes (Van Demark and Hays 1952). It is likely, therefore, that spermatozoan motility may then be of greater importance in the passage of spermatozoa through the genital tract.…”

SummaryLaparotomy was performed on 28 oestrous ewes and either live or dead spermatozoa were deposited in the fallopian tubes or in one uterine horn.Dead spermatozoa appeared to be transported from the cranial extremity of one uterine horn to the body of the uterus and into the contralateral uterine horn as readily as were live spermatozoa but did not pass from the uterus to the fallopian tubes as freely as did the latter. Live spermatozoa passed from the uterus into the cervical canal more freely than did dead spermatozoa but only a small number, relative to the number present in the uterus, was recovered from the caudal portion of the cervix.Mter spermatozoa were deposited in both fallopian tubes, small numbers were recovered from the uteri when live (but not dead) spermatozoa were introduced.The importance of the cervix and the uterotubal junction in limiting the number of spermatozoa that pass in either direction is discussed in relation to the continuity of transport from the cervix to the fallopian tubes in the vaginally insemi· nated ewe. Observations On the survival of spermatozoa in the uterus and fallopian tubes are also presented.
