background: echinococcus granulosus cultivation is very important for improvement of different aspect of medical and veterinary researches. despite many advances in this case, there is a missing link for in vitro life cycle of adult worms and it is fertili-zation. regarding the researchers’ observations, self-fertilization can be done in worms living in dog intestine, but despite all sorts of e...

background: conventional ivf and icsi are two common techniques to achieve fertilization. ivf has long been used for treatment of infertility, although it is not an effective treatment in severe male infertility. the use of icsi has been expanded in severe male factor and fertilization failure after ivf cycle. in spite of the widespread use of icsi in patients with non-male factor infertility, ...

BACKGROUND Minimal stimulation in vitro fertilization (mini-in vitro fertilization) is an alternative in vitro fertilization treatment protocol that may reduce ovarian hyperstimulation syndrome, multiple pregnancy rates, and cost while retaining high live birth rates. OBJECTIVE We performed a randomized noninferiority controlled trial with a prespecified border of 10% that compared 1 cycle of...

Fertilizer efficiency directly affects the production of continuous cropping greenhouse cucumber. So analyzing the fertilizer efficiency is of great significance in providing decision-making support for fertilization of greenhouse cucumber. By establishing the DEA models of continuous cropping greenhouse cucumber and taking existing data samples as study objects, the problems of fertilizer effi...

Birth of babies through in vitro fertilization procedures has Tenewed interest by clinicians as well as laymen in the phenomenon of fertilizatien.

The purpose of this study was to examine: 1) whether caffeine in the fertilization medium under mineral oil is essential for bovine in vitro fertilization by fully capacitated spermatozoa, 2) the minimum concentration of caffeine that shows an adverse effect on the motility of preincubated spermatozoa. Cumulus-oocyte complexes with heterogeneous-appearing ooplasm were matured in in vitro cultur...

In vitro fertilization (IVF) is a process by which an egg is fertilised by sperm outside the body: in vitro . The process involves monitoring and stimulating a woman's ovulatory process, removing an ovum or ova (egg or eggs) from the woman's ovaries and letting sperm fertilise them in a liquid in a laboratory. The fertilised egg (zygote) is cultured for 2–6 days in a growth medium and is then i...

INTRODUCTION Some unexplained infertile couples may have fertilization failure; the in vitro fertilization (IVF) with high insemination concentration (HIC) and intracytoplasmic sperm injection (ICSI) were reported to give better fertilization rate when compared to standard IVF procedure. OBJECTIVE To compare the fertilization rate, abnormal fertilization rate, total fertilization failure rate...
