Casting for determinants of blastocyst yield and of rates of implantation and of pregnancy after blastocyst transfers.

Objective: To identify determinants of blastocyst yield, implantation rate, and pregnancy outcome.

Design: Retrospective analysis of outcomes of 1,653 cycles of IVF.

Setting: Private infertility clinic.

Management of Asherman's syndrome.

Intrauterine adhesions (IUA) or Asherman's syndrome is a multifaceted condition which is being diagnosed with increasing frequency. Although it usually occurs following curettage of the pregnant or recently pregnant uterus, any uterine surgery can lead to IUA. Most women with IUA have amenorrhoea or hypomenorrhoea, but some have normal menses.

Asherman's syndrome.

Asherman's syndrome is being diagnosed with increasing frequency. Although it usually occurs following curettage of the pregnant or recently pregnant uterus, any uterine surgery can lead to intrauterine adhesions (IUA). Most women with IUA have amenorrhea or hypomenorrhea, but up to a fourth have painless menses of normal flow and duration.

The rate at which serum total beta-subunit human chorionic gonadotropin increases after embryo transfer is a predictor of the viability of pregnancy and an identifier of determinants of pregnancy.

Objective: To determine whether elements of treatment associated with faster doubling times of total beta-hCG in serum (beta-t2) in pregnant patients are also associated with a higher likelihood of pregnancy in all patients.

Design: Retrospective analysis of beta-t2 values, elements of ovarian stimulation (COH), and outcomes.

Setting: Private assisted reproductive technology (ART) center.
