1. The mean concentration of BBSP in the seminal bull plasma is 1.53 + 0.30 mg/ml. This con­ centration decreases about 40% after 14 days storage at 4 °C. 2. There is only a small correlation between the concentration of BBSP in the seminalplasma and its fertilization capacity. 3. An artificial doubling of the normal BBSP concentration does not change the results of an artificial insemination. ...

OBJECTIVE To investigate: 1) the impact of clinical varicocele on reactive oxygen species (ROS) levels in neat and washed semen in a proven fertile population; and 2) the correlation between ROS levels, testicular volume, and varicocele grade in the same population of fertile men. DESIGN Prospective controlled clinical study. SETTING Andrology laboratory at tertiary-care hospital. PATIENT...

Background: Intrauterine insemination (IUI) is a common reproductive treating for unexplained infertility (UI). To achieve conception, washed sperm put into the uterine cavity. The success rate of IUI with simultaneous ovulation induction hot topic discussion. In cases infertility, hydrotubation has resulted in significantly higher conception rate. Aim study: to compare effect simple 20 ml sali...

Abstract Study question Do the in vitro motility characteristics of sperm collected using a microfluidic device (ZyMot) differ from those by density gradient centrifugation (DGC)? Summary answer ZyMot-collected had longer-lasting than DGC, but head beat-cross frequency was inferior due to absence washing vitro. What is known already ZyMot (DxNow, Inc., USA) can sort highly motile with low react...

Remains of large marine animals that wash onshore can be difficult to identify due to decomposition and loss of external body parts, and in consequence may be dubbed "sea monsters." DNA that survives in such carcasses can provide a basis of identification. One such creature washed ashore at St. Bernard's, Fortune Bay, Newfoundland, in August 2001. DNA was extracted from the carcass and enzymati...

Artificial insemination with homologous (AIH) or donor semen (AID) is nowadays a very popular treatment option for many subfertile women worldwide. The rationale for the use of artificial insemination is to increase gamete density at the site of fertilisation. The main reason for the renewed interest in artificial insemination is undoubtly the refinement of techniques for the preparation of was...

Objective. There is an asymmetric allocation of technology and other resources for infertility services. Intrauterine insemination (IUI) is a process of placing washed spermatozoa transcervically into the uterine cavity for treatment of infertility. This is a review of literature for the potential use of IUI as a basic infertility treatment in technology-limited settings. Study design. Review o...

Artificial insemination with homologous (AIH) or donor semen (AID) is nowadays a very popular treatment procedure used for many subfertile women worldwide. The rationale behind artificial insemination is to increase gamete density at the site of fertilisation. The sequence of events leading to today's common use of artificial insemination traces back to scientific studies and experimentation ma...

BACKGROUND Assisted reproductive technology with semen washing can offer a significant reduction in risk of sexual and vertical transmission of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) in serodiscordant couples with infected male partner. METHODS Among couples coming to our centre for reproductive problems from January 2001 to December 2003, we selected 43 couples with s...
