OBJECTIVE Melatonin is a scavenger agent that has been used to promote in vitro embryo development. This study was designed to show the effects of melatonin on the quality and quantity rate of preimplantation mouse embryo development and pregnancy. MATERIALS AND METHODS In this experimental study, super ovulated, mated mice were killed by cervical(More)
BACKGROUND It is important to protect oocytes and embryos from oxidative stress in the culture medium. Melatonin has been shown to be a direct free radical scavenger. OBJECTIVE Effect of melatonin during in vitro oocyte maturation, fertilization and embryo development of mouse oocytes was evaluated. MATERIALS AND METHODS Oocytes from supper-ovulated(More)
BACKGROUND AND OBJECTIVE Sperm morphology analysis (SMA) is an important factor in the diagnosis of human male infertility. This study presents an automatic algorithm for sperm morphology analysis (to detect malformation) using images of human sperm cells. METHODS The SMA method was used to detect and analyze different parts of the human sperm. First of(More)
Background. Attention-deficit hyperactivity disorder (ADHD) is one of the most common psychiatric disorders among children. The aim of this study was to evaluate risk factors for ADHD in children. Method. In this case-control study, 404 children between 4 and 11 years old were selected by cluster sampling method from preschool children (208 patients as(More)
Caudal epidural anesthesia is commonly utilized in veterinary medicine to allow diagnostic, obstetrical, and surgical intervention, in the perineal region of large animal. The aim of this study is to directly compare the time of onset and duration of analgesia produced by a tramadol and lidocaine-tramadol combination with that produced by lidocaine(More)
BACKGROUND AND OBJECTIVE Aspiration of a good-quality sperm during intracytoplasmic sperm injection (ICSI) is one of the main concerns. Understanding the influence of individual sperm morphology on fertilization, embryo quality, and pregnancy probability is one of the most important subjects in male factor infertility. Embryologists need to decide the best(More)
BACKGROUND Abnormal oocyte morphology has been associated with the hormonal environment to which the gametes are exposed. OBJECTIVE In this study, we evaluated the oocytes morphology, fertilization rate, embryos quality, and implantation rate resulted of retrieved oocytes in different times after human chorionic gonadotrophin (HCG) administration. (More)
BACKGROUND We designed this study to detect the cryoinjury rate on human sperm after serial freezing and thawing, taking into consideration the effects of using cryovials and straws. MATERIALS AND METHODS In this experimental study, semen specimens obtained from 15 subjects were divided into normozoospermic and oligozoospermic groups. Each of the(More)
