The effects of prognostic factors on pregnancy success among women 39 years or older having intracytoplasmic sperm injection

Intracytoplasmic Sperm Injection – Factors Affecting Fertilization

The ICSI has become method of choice to achieve fertilization. Fertilization is possible in cases in which the sperm motility and ability to penetrate the zona pellucida are impaired. Injection is possible with sperm obtained from ejaculation, microsurgical epididymal sperm aspiration (MESA), percutaneous epididymal sperm aspiration (PESA), or testicular sperm extraction (TESE). In addition, in...

Intracytoplasmic Sperm Injection

Intracytoplasmic Sperm Injection (ICSI) is an assisted reproductive technique [4] (ART) initially developed by Dr. Gianpiero D. Palermo [5] in 1993 to treat male infertility [6]. It is most commonly used in conjunction with in vitro [7] fertilization [8] (IVF) or a less commonly used technique called zygote intrafallopian transfer [9] (ZIFT). In natural fertilization [8], the sperm [10] must pe...

Intracytoplasmic sperm injection, results in women older than 39, according to age and the number of embryos replaced in selective or non-selective transfers.

The aim of this study was to assess the results of intracytoplasmic sperm injection (ICSI) in a large cohort of women older than 39 according to age and to embryo transfer policy. In all, 736 ICSI cycles were analysed retrospectively. In 576 (78.3%) cycles an embryo transfer was carried out. The embryo transfer was defined as non-selective when all the available embryos were transferred, and as...

Intracytoplasmic sperm injection (ICSI)

IVF has become a well-established treatment for certain types of infertility, including long-standing infertility due to tubal disease, endometriosis, unexplained infertility or infertility involving a male factor. Soon it became clear that certain couples with severe male-factor infertility could not be helped by conventional IVF. Extremely low sperm counts, impaired motility and/or abnormal m...
