Motility characteristics (assessed subjectively and with computer-assisted semen analysis) and membrane status (after staining with chlortetracycline) of washed and non-washed frozen-thawed ram spermatozoa were evaluated after incubation in buffer and buffer containing autologous whole seminal plasma or one of its two fractions: the pellet of membrane vesicles obtained by ultracentrifugation (a...

Transgenic nonhuman primate models are an increasingly popular model for neurologic and neurodegenerative disease because their brain functions and neural anatomies closely resemble those of humans. Transgenic Huntington's disease monkeys (HD monkeys) developed clinical features similar to those seen in HD patients, making the monkeys suitable for a preclinical study of HD. However, until HD mo...

PURPOSE More than 30 million couples throughout the world are using vasectomy as a method of birth control. It is estimated that up to 6% of men who undergo voluntary sterilization will eventually request reversal, despite the high cost and relatively low success rate of the procedure. We identified characteristics that predict which vasectomy patients may request reversal. We also examined the...

The objective of the study was to compare embryo development rates after transfer of oocytes collected 22 or 33 h after hCG injection into recipients inseminated within the uterus or the oviduct. Oocytes were collected at approximately 22 or 33 h after hCG injections and incubated for approximately 16 or 1.5 h, respectively, before transfer. Intrauterine inseminations using 1 x 10(9) progressiv...

Infertility management has become more substantial and relevant with an increase in the number of infertile patients as well as advances in the science of reproduction. The objective of our study was to assess the factors predicting the treatment outcome of a new assisted reproductive technique, intrauterine tuboperitoneal insemination (IUTPI) in the treatment of infertile patients. 118 cases, ...

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 ...

The use of the GnRH antagonists during ovarian stimulation for intrauterine insemination is relatively recent. The primary aim was to improve the timing of the inseminations on working days. However, according to published data, the consequences on pregnancy rate remain uncertain. Moreover, the impact of this strategy on stimulation's parameters, specifically on the size of the follicle cohort,...

Background: Every human being, especially a married couple, wants children. Obstacles to obtaining children are called infertility. One of the Assisted Reproductive Technology (ART) procedures used for treating infertility is intrauterine insemination (IUI), non-invasive procedure with affordable costs. The success IUI influenced by many factors, one which sperm agglutination.
 Objective: ...
