The objective was to determine whether granulocyte-macrophage colony-stimulating factor (GM-CSF) stimulates development of bovine embryos. In each experiment, oocytes were fertilized in vitro, GM-CSF was added to embryo culture medium at 8-10 h or 5 days after insemination, and development was monitored as the proportion of oocytes that formed blastocysts. Addition of recombinant bovine GM-CSF ...

This paper presents the findings of the third phase of a longitudinal study of families created by assisted reproduction. The quality of parent-child relationships was examined close to the adolescent's 18th birthday in 26 in vitro fertilization (IVF) families and 26 donor insemination (DI) families in comparison with 38 adoptive families and 63 natural conception families matched for demograph...

There are many studies on the storage of honey bee semen. Due to its unique structure, semen varies according period but is suitable for short-term conditions. However, in terms long-term conditions, developments mammals have not been caught. It known that more needed this subject. The great advantages effective role eliminating problems inbreeding after a while pure breed enterprises, increasi...

Over the past decade, there has been increasing interest in the application of reproductive technology to the conservation and management of natural populations of deer. The application of assisted reproduction technologies within natural population of deer is in its infancy. However, its future potential is enormous, particularly in relation to genetic management or conservation. This paper re...

Background: To compare the effect of GnRH agonist administration with vaginal progesterone on serum progesterone in Luteal phase in control ovarian hyper stimulation and intrauterine insemination cycles Materials and Methods: In this clinical trial, 242 infertile patients because of UEI (unexplained inferetility candidate for ovarian stimulation and intrauterine insemination reffering to infert...

Intrauterine laparoscopic insemination is diffuse in sheep breeding, yet requires veterinary expertise and expensive equipment. Our aim was to evaluate the time required, reproductive outcome post-operative complications of mini invasive laparotomic intrauterine insemination, as an alternative approach laparoscopy. A total 115 Sopravvissana breed ewes were enrolled, including 75 adults 40 lamb ...
