A 32 year old female presented with a history of 2 miscarriages at 6 weeks of pregnancy followed by 10 years of infertility. A bilateral wedge resection for polycystic ovaries had been carried out 8 years ago and had resulted in regular periods. A post-surgical laparoscopy revealed a blocked left tube and a tortuous right tube with multiple adhesions, which were partially freed. An unsuccessful...

introduction: sperm viability test is important in diagnosis and treatment of male infertility. the common test is e&n; and host which they are based on membrane permeability and integrity. the aim of this study was to evaluate mtt assay as a sperm viability test based on mitochondrial activity. materials and methods: washed sperm samples were co-incubated with mtt in different media and differ...

Problem statement: The ability of a blast cyst to hatch, or escape, from the Zona Pellucida (ZP) that surrounds and protects the embryo during its first few days of development is one of many critical events that must occur for successful reproduction. Implantation of the embryo in the uterine lining is impossible unless hatching occurs. Hard or thick ZP will therefore impaire the implantation ...

BACKGROUND There has been an increase in number of obese infertile females booked for advanced infertility treatment procedures like in vitro fertilization (IVF) and intra cytoplasmic sperm injection (ICSI). The knowledge of impact of body mass index (BMI) on reproductive outcome can help to counsel these patients. OBJECTIVE To compare reproductive outcome in females of different BMI after IC...

The aim of this report has been evaluating protamine content and DNA integrity of two patients with globozoospermia undergoing Intra Cytoplasmic Sperm Injection (ICSI). Semen analysis was carried out according to WHO criteria. Protamine deficiency and DNA fragmentation was assessed using Chromomycin A3 and sperm chromatin dispersion assay respectively. ICSI and chemical activation were carried ...

BACKGROUND Irradiation is one of the major causes of induced sperm DNA damage. Various studies suggested a relation between sperm DNA damage and fertilization rate after intra-cytoplasmic sperm injection (ICSI). OBJECTIVE In this study, fertilization rate and premature chromosome condensation (PCC) formation after ICSI of hamster oocytes with irradiated sperms from normal and oligosperm indiv...

OBJECTIVE Melatonin, the chief secretory product of the pineal gland, regulates dynamic physiological adaptations that occur in seasonally breeding mammals as a response to changes in daylight hours. Because of the presence of melatonin in semen and the mem- brane melatonin receptor in spermatozoa, the impact of melatonin on the regulation of male infertility is still questionable. The aim of t...
