The intrauterine inseminator (IUI) was developed to provide the method of depositing dog semen into the uterine body instead of the vagina. The IUI consists of a vaginal endoscope, a balloon sheath, and injection catheter. When the endoscope is inserted into the vagina and the balloon expanded with air, the cervical os becomes visible so a injection catheter can be inserted through the cervix f...

OBJECTIVE To determine the effect on fertility of large-volume uterine lavage with lactated Ringer's solution (LRS) performed immediately prior to insemination in mares. DESIGN Prospective randomized controlled study. ANIMALS 20 mares. PROCEDURE Control mares (n = 10) were inseminated with 1 billion (estimated before cooling) progressively motile spermatozoa that had been cooled in a pass...

Acetylcholine, injected im into does immediately after natural mating, significantly increased the number of sperm recovered 1 h later from the vagina and cervices but not from the oviducts. Acetylcholine caused immediate increases in the frequency and amplitude of uterine contractions as measured by strain-gauge force transducers attached to the serosa and recorded by physiograph; contraction ...

Background & aim: Inability in childbearing is considered a deviation from the norms; therefore, the stigmatized women need to develop some effective strategies to meet this tough challenge. The present study was conducted to determine the effect of infertility counseling programs on perceived stigma among infertile women who were candidates for intrauterine inseminati...

1. Because studies of the metabolic problems of the human intra-uterine growth-retarded neonate are limited by ethical considerations we have used the intra-uterine growth-retarded piglet as an animal model. Total body-glucose kinetics were measured in 16 intra-uterine growth-retarded and 11 normal piglets from the same litters with [3H]glucose as a tracer. 2. The intra-uterine growth-retarded ...

Introduction Recently, a new procedure for intrauterine insemination (IUI) in sows has been established (1,2). The procedure consists of a specially designed catheter that can be passed through the cervix allowing the deposition of sperm in the uterus. Using this technique, the number of spermatozoa per dose can be reduced by up to 1 billion spermatozoa. It has been demonstrated that the IUI te...

The aim of the study was to determine whether neutrophil numbers (PMN), trypsin-inhibitor capacity (TIC), lysozyme, N-acetyl-beta-D-glucosaminidase (NAGase), beta-glucuronidase (B-Gase), total protein, and plasmin in uterine lavage fluid of postpartum (p.p.) mares, either at the time of foal heat insemination or around the time of arrival of the embryo in the uterus, could be used in predicting...
