This study aimed to evaluate the impact of a short insemination procedure on embryo development, assess the reliability of a fertilization check prior to the appearance of pronuclei and elucidate the role of rescue intracytoplasmic sperm injection (R-ICSI). Patients who had ≥9 eggs, were aged <38 years and had normal semen samples were included. The sibling eggs of each patient were divided int...

Insemination at the uterotubal junction is a practical technique that can be used to decrease the number of spermatozoa used per insemination. Video endoscopic insemination allows one to visualize the uterotubal papilla during the insemination and provide higher pregnancy rates than a flexible AI catheter. Further studies are needed to determine if a consistent technique can be developed for de...

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...

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...

OBJECTIVE We evaluated the efficacy of fresh versus frozen sperm in therapeutic donor insemination. STUDY DESIGN Fifty-seven women underwent 72 courses of treatment (a maximum of six therapeutic donor insemination cycles--three fresh and three frozen) totaling 198 cycles. Each woman served as her own control and was prospectively randomized to receive a single, timed insemination of either fr...

Optimised insemination strategies on pig farms aim at reducing the number of inseminations, without reducing reproductive performance. At the moment, one insemination with good quality semen can result in good fertilisation results when insemination takes place in a 24 h period before ovulation. However, knowledge of this optimal period is not sufficient to limit the number of inseminations to ...
