OBJECTIVE To identify whether sperm characteristics after washing and/or ovulation induction cycle characteristics can predict the occurrence of multiple conception in patients undergoing ovarian stimulation and IUI. DESIGN Retrospective study. SETTING A gynecology clinic and an andrology laboratory at a tertiary care facility. PATIENT(S) One hundred patients with single pregnancies and 2...

In this study, quantitive characteristics and chemical composition of in roach (Rutilus rutilus caspicus) sperm were investigated. Sperm traits included sperm movement duration, percentage of motile spermatozoa, sperm density, spermatocrit and sperm volume. Some seminal plasma characteristics (sodium, potassium, calcium, magnesium and chloride) were investigated. In addition, some metabolites o...

This study was conducted to determine whether pentoxifylline has an in vitro effect on sperm motion characteristics in normozoospermic men. The subjects of the study were 15 male volunteers. After the spermatozoa were washed with mBWW medium, the sperm suspension was divided into two aliquots: one was treated with 1 mg/ml pentoxifylline, the other was used as a control. The sperm motion charact...

OBJECTIVE To determine whether peritoneal fluid from women with endometriosis contributes to infertility by impairing sperm motion and functional characteristics. METHODS Women with endometriosis (n = 20) underwent laparoscopy for infertility or pelvic pain. Patients undergoing tubal ligation served as controls (n = 14). Peritoneal fluid was aspirated from women with endometriosis, or from wo...

Background: Intra-cytoplasmic sperm insemination, the ICSI, is considered as the one most routine treatment of male infertility. Although the genetic inheritance of an individual is based on the genetic contribution from both the oocyte and sperm, considering the fact that ICSI by passes all the barriers to natural fertilization much emphasis was given to oocyte quality to improve the ICSI outc...

background: pentoxifylline (px) is a methyl xanthine derivative that influences the sperm motion characteristics and l-carnitine (l-c) is an amino acid that is naturally produced in the body. in general, separate administration of px and l-c has been reported to be effective on preserving sperm motility in vitro, and also when is consumed orally by the idiopathic oligoasthenoteratozoospermia (i...

Black Bengal goat is the heritage and one of the potential genetic resources of Bangladesh. Genetic and phenotypic parameters for semen characteristics and their relationships with scrotal circumference in Black Bengal bucks were estimated in this experiment. Genetic parameters were estimated by residual maximum likelihood procedure, fitting an animal model ignoring maternal genetic or permanen...
