The effect of paternal age on outcome in assisted reproductive technology using the ovum donation model.

Objective: To determine the effect of paternal age (PA) on implantation and live birth rates in an ovum donation program.

Design: Retrospective study.

Methods: A total of 237 ovum donor cycles were reviewed.

Obstetric implications for and identification of women with a normal clomiphene citrate challenge test result who have a poor response to gonadotropins.

Objective: To determine the incidence and obstetric implications and to identify prospectively women with a poor response to hMG with a normal clomiphene citrate challenge test (CCCT) result.

Design: Retrospective chart review.

Setting: Tertiary fertility center.

Use of a gonadotropin-releasing hormone antagonist for endometrial maturation and synchronization in an ovum recipient.

Objective: To report the novel use of hMG and the GnRH antagonist for endometrial preparation and synchronization in a woman participating in an ovum donation program who was resistant to endometrial preparation with estrogen replacement.

Design: Case report.

Setting: Tertiary fertility center.

Ultrasound detection of pyometra at the time of embryo transfer after ovum retrieval for in vitro fertilization.

Objective: To report the detection of pyometra after ovum retrieval for IVF with the routine use of ultrasound-guided embryo transfer.

Design: Case report.

Setting: Tertiary fertility center.

Elevated serum progesterone-to-estradiol ratio during gonadotropin stimulation for intrauterine insemination or in vitro fertilization is not associated with diminished ovarian reserve.

Objective: To determine whether an elevated serum P:E2 ratio on the day of hCG administration during gonadotropin stimulation for intrauterine insemination (IUI) or IVF is associated with diminished ovarian reserve.

Design: Retrospective chart review.

Setting: Tertiary fertility center.
