What's the difference between superfetation and uterus?
Superfetation
Definition:
(n.) The formation of a fetus at the result of an impregnation occurring after another impregnation but before the birth of the offspring produced by it. This is possible only when there is a double uterus, or where menstruation persists up to the time of the second impregnation.
Example Sentences:
(1) Combined pregnancies rarely occur without treatment with ovulation inducing agents by superfecundation and superfetation.
(2) Suspected superfetation was investigated in a Glasgow hybrid stock of mice.
(3) Intervals between successive deliveries that are shorter than the normal duration of gestation do not necessarily indicate superfetation and this phenomenon may be rare among hares in captivity as well as in the wild.

(5) Those phases reviewed include ovulation, fertilization and tubal passage of sperm and fertilized ova, capacitation of spermatozoa, the spacing of ova along the uterus, preimplantation stages of the uterus and uterus-blastocyst interaction, decidualization, the zona pellucida, normal and delayed nidation, superfetation, and the parthogenetic activation of eggs.
(6) This observation reports a case of human superfetation.
(7) The possibility of inducing superfetation in hares by artificial insemination (AI) was investigated.
(8) Ovulation during pregnancy is hypothesized to be the cause of superfetation found in mares.
(9) The second gestation was of normal length and superfetation was not therefore considered to be the cause of the anomalous litters.
(10) In humans, superfetation has been recorded secondary to ovulation induced by clomiphene citrate.
(11) This case report should support earlier evidence that superfetation in the bovine can and does occur.
Uterus
Definition:
(n.) The organ of a female mammal in which the young are developed previous to birth; the womb.
(n.) A receptacle, or pouch, connected with the oviducts of many invertebrates in which the eggs are retained until they hatch or until the embryos develop more or less. See Illust. of Hermaphrodite in Append.
Example Sentences:
(1) In these bitches, a strain of E coli identical to the strain in the infected uterus was isolated.
(2) The combination of an over-distended uterus caused by a multiple-fetus pregnancy with therapeutic bed-rest may cause mechanical ileus.
(3) There was no significant difference in sialic acid concentration in the uterus during the proliferative and luteal phases of the menstrual cycle.
(4) In this study 470 bitches were inseminated; 405 with fresh semen into the cranial vagina and 65 with frozen semen transcervically into the uterus.
(5) The clinical and pathological features of a patient with giant cell arteritis of the uterus and ovaries are described.
(6) If deaths from ruptured uterus are to be avoided, early diagnosis is essential.

(10) Likewise, [3H]estradiol-receptor complexes from rabbit uterus, Squalus oviduct, or mouse testis bound minimally to Squalus testicular chromatin.
(11) We have studied the postnatal ontogeny of creatine kinase (CK) and the glycolytic enzymes phosphoglycerate kinase (PGK), phosphoglycerate mutase (PGM), enolase (En), and pyruvate kinase (PK) in rat brain and uterus.
(12) Compared with anteverted (N = 243) or axial (N = 149) locations, the retroverted uterus (N = 66) was associated with a lower mean sample weight per aspiration (22, 18, and 15 mg, respectively; P less than .01) and a greater frequency of multiple-pass procedures (23, 31, and 52%, respectively; P less than .0001).
(13) These plasmin-cleaved peptides are derived from the COOH terminus of C2b, and they induce the contraction of estrous rat uterus.

(20) LSN lesions in hypophysectomized rats have no effect on the ovary and uterus weights as compared to hypophysectomized ones, but decrease the size of mature ovarian follicles against a background of hypophysectomy or LSN lesions.
