The use of artificial insemination (AI) with fresh semen has resulted in many benefits for the management of dog breeding, but there are disadvantages that can sometimes be overlooked. Furthermore, poorer quality semen arising as a result of cryopreservation necessitates uterine insemination, which raises the potential for surgical insemination. A number of significant ethical concerns have bee...

A 26-year-old patient presented at the emergency department because of uterine bleeding for the previous 3 days. She had undergone voluntary termination of pregnancy by curettage 2 months before. Upon clinical examination, metrorrhagia was moderate, with heart rate: 90/min, blood pressure: 110/80 mmHg and temperature: 36.9°C. Intra-vaginal ultrasound examination showed a heterogeneous intra-ute...

Although premature separation of normally implanted placenta is considered the most serious complication of pregnancy, knowledge of uterine behaviour during this con­dition is meager, on the basis of electronic recording of intra-uterine pressure two type of contraction pattern has been identified.  In type I uterine tonus has values below 30mmHg  with a frequency of 4-9 contractions per 10 m...

Background: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders, affecting 5-10% of reproductive aged women. High levels of androgen hormone can be accounted as the most important symptoms in PCOS. Androgen is the precursor of steroid biosynthesis in ovary. The transport of cholesterol to the inner mitochondrial membrane through StAR protein is also necessary for andr...

Background: Follicle stimulating hormone (FSH) receptor plays an important role in FSH signaling during reproductive development. Any changes in FSHR gene is resulted in alteration of amino acid in protein chain, consequence to affect the binding affinity, intracellular signaling and expression levels of FSHR. FSHR polymorphisms can be involved in etiology of many reproductive disorders such as...

In this study we evaluated the value of short-time insemination and early rescue intra-cytoplasmic sperm injection (ICSI) in preventing the occurrence of complete fertilisation failure for mild or moderate male infertility patients. A total of 866 couples with borderline semen who underwent in vitro fertilisation treatment in 2010 were included. Regular insemination was performed between Januar...

Background: Urinary human chorionic gonadotropin is the most widely used medicine for ovulation in ovarian stimulation cycles. Recently however, recombinant HCG has also become commercially available. This study presents compare the use of recombinant hCG with urinary hCG during controlled ovarian hyperstimulation and intra uterine insemination (COH-IUI ) cycles Materials and Methods: This is s...

The objective of this study was to compare the number of recovered spermatozoa, in different parts of the uterine horn and oviduct in gilts, after insemination with fractionated (experiment) and non-fractionated (control) liquid stored semen. The number of spermatozoa and volume of backflow was also investigated. Twenty three cross-bred gilts were used in the study. They were divided into 2 gro...
