Two successful pregnancies achieved by converting an fertilization cycle to an intrauterine insemination cycle in five cases with documented premature ovulation.

We here report two successful pregnancies obtained by converting an fertilization (IVF) cycle to an intrauterine insemination (IUI) cycle in five poor responder patients whose oocyte pick-up (OPU) procedures were canceled due to documented premature ovulation immediately before OPU. To our knowledge, this is the first article that demonstrates that switching an IVF cycle to an IUI cycle when premature ovulation occurs on the day of OPU can produce successful pregnancies, even in poor responder patients.

Outcome of intracytoplasmic sperm injection using fresh and cryopreserved-thawed testıcular spermatozoa in 83 azoospermic men with Klinefelter syndrome.

Aim: To report the outcome of intracytoplasmic sperm injection (ICSI) cycles using fresh or cryopreserved-thawed testicular spermatozoa of men with Klinefelter syndrome (KS).

Methods: Medical records of 83 azoospermic men with KS who underwent testicular sperm extraction (TESE) were reviewed. The clinical parameters for predicting sperm retrieval and fertilization, implantation, pregnancy and live birth rates of ICSI cycles in these patients were evaluated.

Birth of a healthy boy using fresh testicular sperm in a patient with Klinefelter syndrome combined with Kartagener syndrome.

Objective: To report a case of Klinefelter syndrome combined with Kartagener syndrome.

Design: Case report.

Setting: Private IVF center.

Smooth endoplasmic reticulum aggregations in all retrieved oocytes causing recurrent multiple anomalies: case report.

Objective: To document the relationship between smooth endoplasmic reticulum (SER) aggregations and recurrent fetal anomalies.

Design: Case report.

Setting: Private IVF center.

Efficiency of follicle-stimulating hormone, commenced in the luteal phase, for overcoming a poor response in assisted reproduction.

Aim: The efficacy of commencement of recombinant follicle-stimulating hormone (recFSH) during the luteal phase in the long-protocol gonadotropin-releasing hormone (GnRH) agonist regimen in poor responders was compared with the conventional protocol in a prospective, randomized, controlled study.

Methods: Forty-two women who responded poorly to previous conventional controlled ovarian hyperstimulation were included in the study. Recombinant FSH (150 IU) was started simultaneously with the GnRH agonist long protocol in the study group.

Effect of heat-induced hypermotility on pregnancy rate in intrauterine insemination for male factor infertility associated with asthenospermia: a prospective, randomized, controlled study.

Objective: To assess the effect of mild heat for the enhancement of sperm fertilizing capacity in intrauterine insemination for male factor infertility associated with asthenospermia.

Material And Method: Prospective, controlled, clinical study. Male factor infertility associated with asthenozoospermia was the criteria for inclusion.

Intrauterine insemination with double ejaculate compared with single ejaculate in male factor infertility: a pilot study.

The aim of this study was to compare the efficiency of using a double ejaculate with the efficiency of using a single ejaculate for intrauterine insemination in male subfertility. Eligibility for the study was a total motile sperm count between 1 x 10(6) and 5 x 10(6) on postwash sperm analysis. Thirty-nine couples were randomized to the study group, while another 50 couples were randomized to serve as the control group.

Clinical pregnancies and livebirths achieved by intracytoplasmic injection of round headed acrosomeless spermatozoa with and without oocyte activation in familial globozoospermia: case report.

We report the successful outcome of intracytoplasmic sperm injection (ICSI) treatment in two siblings with familial globozoospermia. After controlled ovarian hyperstimulation and oocyte pick-up, retrieved oocytes were mechanically activated before ICSI and a fertilization rate of 33.3% was achieved in the first case.

Luteal start of exogenous FSH in poor responder women.

Purpose: To compare the effectiveness of using recFSH commenced in the luteal phase with a long GnRH agonist protocol or in the early follicular phase with a short GnRH agonist protocol, in infertile women designated as poor responders undergoing treatment with assisted reproduction in a prospective, randomized, controlled study.

Materials And Methods: Forty-two couples undergoing an ICSI cycle of whom female partner diagnosed as poor responder were included in the study. Recombinant FSH was given daily from day 21 of the previous cycle upon initiation of GnRH agonist in the study group.

The effect of retained embryos on pregnancy outcome in an in vitro fertilization and embryo transfer program.

Objective: The purpose of this study was to determine the incidence of retained embryos and its impact on pregnancy outcome in the absence of known risk factors like blood and mucus in the transfer catheter. The factors that could be associated with embryo retention were also investigated.

Study Design: The results of all embryo transfer procedures performed at Ankara IVF Center between January 2003 and December 2005 were analyzed retrospectively.

Genetic aspects of human male infertility: the frequency of chromosomal abnormalities and Y chromosome microdeletions in severe male factor infertility.

Objective: The main purpose of this study is to detect the frequency and type of both chromosomal abnormalities and Y chromosome microdeletions in patients with severe male factor infertility and fertile control subjects. The association between the genetic abnormality and clinical parameters was also evaluated.

Methods: This study was carried out in 208 infertile and 20 fertile men.
