The objective of this retrospective study was to evaluate the factors influencing developmental stage of bovine embryos recovered from superovulated dairy cattle 7 d after estrus. From 217 superovulated dairy cows and heifers, 2,211 eggs were recovered, of which 1,495 were classified as transferable embryos based on morphological evaluation of developmental stage and quality. From the evaluated...

BACKGROUND Pseudomonas aeruginosa may cause venereal disease and infertility in horses. A Pseudomonas aeruginosa - carrier stallion, often unresponsive to artificial vagina collection, was used to naturally breed mares. Semen collected from the same stallion was also used to perform artificial inseminations. Pregnancy rates, embryo quality and incidence of uterine infection were compared betwee...

Background To compare the pregnancy outcomes after two embryos versus three embryos transfers (ETs) in women undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles. MaterialsAndMethods This retrospective study was performed on three hundred eighty seven women with primary infertility and with at least one fresh embryo in good quality in order to transfer at each ...

embryo culture were used to produce inter specific walnut hybrid plants between juglans nigra l. and j. regia l. developed ovaries were collected from j. rejia female flowers which were pollinated with j. nigra pollen grain by high dusting on a mature tree. in order to isolate embryos, exocarps were aseptically removed. isolated embryos from ovules at different developmental stages were transfe...

Embryonic midbrain micromass cultures were exposed for five days to ochratoxin A (OTA) at seven concentrations (ranging from 0.16 to 10 microg/mL). Cell viability was assessed in neutral red uptake test (NRU), and differentiation - by immunoenzymatic determination of structural proteins (beta(III)-tubulin, MAP2, GFAP) expression level as well as by computer image analysis. Dose dependent decrea...

The purpose of this study was to determine the effect of heparin-binding epidermal growth factor (HB-EGF) on human embryo development in vitro from days 2 to 14 post-insemination. Embryos were cultured in a complex serum-free medium (CSFM3) in the absence and presence of 1 nM and 100 nM HB-EGF. Development to the blastocyst stage of A-C-grade embryos (A grade = highest quality) was improved in ...

Intracytoplasmic sperm injection is more being used for non-male factor indications, although it was developed overcoming infertility of males because pregnancy rate in vitro fertilization still < 40%. This work aims at evaluating the injecting cycle fertilization/ efficiency infertile women and factors that predicting clinical rate. Al-Nahrain University High Institute Infertility Diagnosis...

A cycle of IVF was begun for her. After an antagonist cycle, 10 oocyte have been retrieved by puncture and three 8-cell grade 1 embryos have been freshly placed in the uterus. Four weeks after transferring the embryo, transvaginal ultrasound (TVS) was performed in which a gestational sac of about 4 mm without fetal pole and yolk sac were reported in the uterine cavity. No abnormality was report...
