Counts were made of the numbers of spermatozoa in the Fallopian tubes of ewes 24 hr after mating or after insemination with either sheep or goat semen. Spermatozoa were recovered from all five mated ewes (10/10 tubes), from all eight ewes inseminated with sheep semen (13/15 tubes) and from four of eight ewes inseminated with goat semen (7/16 tubes). The calculated mean numbers of spermatozoa pe...

WHAT are vasectomy and tubal ligation? These are two surgical procedures for permanent birth control. Vasectomy is sterilization in men, where the vas deferens (two tiny tubes, one connected to each testicle) are cut to prevent the semen from being ejaculated. Tubal ligation is sterilization for women, where the fallopian tubes are ligated (tied by sutures) to prevent the ova (eggs) from being ...

Recently, the distal Fallopian tube has attracted considerable attention not only as site of origin for serous cancer in women with BRCA mutations, but also as the anatomical location where the majority of serous ovarian cancers apparently develop. Consequently, the Fallopian tube may be the unique location where early ‘ovarian’ cancers can be found—which would contradict the long-standing impr...

BACKGROUND The physiological regulation of ciliary beat frequency (CBF) within the fallopian tube is important for controlling the transport of gametes and the fertilized ovum. Progesterone influences gamete transport in the fallopian tube of several mammalian species. In fallopian tubes isolated from cows, treatment with 20 micromolar progesterone caused a rapid reduction of the tubal CBF. The...

Background The current research to the best of my knowledge is the first to compare the pregnancy outcome between ultrasound-guided tubal recanalization (UGTR) using a special fallopian tubal catheter, and office-based micrhysteroscopic ostial dilatation (MHOD) using the same tubal catherter in infertile women with previously diagnosed bilateral proximal tubal obstruction (PTO).

OBJECTIVES This study is aimed at determining the pattern of abnormalities in the Hysterosalpingograms of patients who attended the Radiology Unit of Ebonyi State University Teaching Hospital, Abakaliki. METHOD The 188 hysterosalpingograms conducted between January 2002 to December 2005 were analysed.. RESULTS The mean age in this study was 31 years. Forty-one (21.8%) Hysterosalpingograms w...

Background Transfer of micro-Injected oocytes into fallopian tubes is an alternative procedure for IVF-ET with a similar success rate. This could be either done immediately after ovum pick-up microinjected oocytes intrafallopian transfer (MIFT) or after a time interval zygote intrafallopian transfer (ZIFT). This study was designed to compare the outcomes of the two procedures. MaterialsAndMetho...

A large library of hen oviduct cDNA-pCR1 recombinant plasmids has been established in Escherichia coli X1776. From this library, ovomucoid cDNA and lysozyme cDNA-bearing plasmids have been identified. One of these plasmids, pMu7, yielded the sequence of the 3'-untranslated region of ovomucoid mRNA.
