Since the conclusion of data collation from previously published work, a further 352 inseminations using frozen-thawed dog semen by endoscopic-assisted transcervical insemination (EIU) have been performed by the author. Insemination was performed on the second day in which crenulation of the anterior vagina was detected in conjunction with a progesterone concentration of >10 ng/ml. All semen sa...

OBJECTIVE To identify prognostic factors influencing the outcome of infertility treatment using intrauterine insemination with donor semen (IUI-D). DESIGN Retrospective study of all patients undergoing IUI-D between August 1st, 1990 and July 31st, 1998. SETTING University-affiliated infertility clinic. PATIENTS Three hundred and five couples undergoing 1131 IUI-D treatment cycles. MAIN ...

A total of 415 fat tailed ewes were randomly assigned to two groups to assess the effect of duration of melengestrol acetate (MGA) (9 versus 12d) administration on reproductive parameters associated with laparoscopic artificial insemination. At the end of MGA treatment, ewes in each group were subdivided and inseminated with one of two different insemination doses (10×10(7) or 20×10(7) sperm pe...

Sperm transfer through the epididymis, a prerequisite for insemination of cat fleas, Ctenocephalides felis (Bouché) was stimulated by exposure of unfed male fleas to juvenile hormone III residues for 3 d at 25 degrees C or exposure of unfed fleas to 37 degrees C for 6 d. Sperm transfer was completed at least three times faster in unfed males held at 37 degrees C than in those held at 25 degrees...

Gonorrhoea is now pandemic throughout the world with about 150 million cases occurring annually. In the United States alone, the annual incidence of gonorrhoea has been estimated by the Public Health Service at 21 million, and this sharp increase has resulted in many physicians becoming reacquainted with this interesting and complex disease from both the clinical and the epidemiological viewpoi...

Intrauterine insemination (IUI) as a type of artificial insemination involves the placement of sperm directly into the uterus at the time of ovulation, either in a natural menstrual cycle or following ovarian stimulation. The process allows the concentration of sperm in a small volume of culture media and then the concentrated sperm is placed into the uterus through a transcervical catheter. IU...
