Endometriosis Affects Oocyte Morphology in Intracytoplasmic Sperm Injection Cycles?

OBJECTIVE To identify associations between presence of endometriosis and oocyte defects, embryo developmental potential, and cycle outcomes. METHODS This study looked into the impact of endometriosis on oocyte and embryo quality, and blastocyst formation probability. Endometriosis was also correlated with cycle characteristics. In order to avoid age-related bias, in the first analysis only pa...

Subclinical hypothyroidism: Is it important in intracytoplasmic sperm injection cycles?

OBJECTIVE To compare intracytoplasmic sperm injection (ICSI) outcomes of women with subclinical hypothyroidism with those of euthyroid women. MATERIALS AND METHODS A retrospective case-control study was conducted. Out of 2529 ICSI cycles evaluated, 41 women with hypothyroidism, 28 women with hyperthyroidism, and 128 women with subclinical hyperthyroidism were excluded, and 2336 cycles were an...

Testicular versus epididymal spermatozoa in intracytoplasmic sperm injection treatment cycles.

BACKGROUND Normal fertilization and ongoing pregnancy can be achieved using intracytoplasmic sperm injection (ICSI), even with severely immature spermatozoa. However, the published literature documents conflicting results as to the outcome of ICSI. METHODS Surgical extraction of spermatozoa in 111 ICSI treatment cycles performed over five years at the Assisted Conception Unit (ACU), Universit...

Intracytoplasmic sperm injection (ICSI).

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...
