OBJECTIVES We evaluated outcomes in couples treated for infertility with natural procreative technology (NaProTechnology [corrected] NPT), a systematic medical approach for optimizing physiologic conditions for conception in vivo, from an Irish general practice. METHODS All couples receiving treatment from 2 NPT-trained family physicians between February 1998 and January 2002 were studied. Th...
BACKGROUND One-third of subfertile couples have no identifiable cause for their inability to conceive. In vitro fertilisation (IVF) is a widely accepted treatment for this condition; however, this treatment is invasive and expensive and is associated with risks. OBJECTIVES To evaluate the effectiveness and safety of IVF compared with expectant management, unstimulated intrauterine inseminatio...
BACKGROUND Clomiphene is the current first-line infertility treatment in women with the polycystic ovary syndrome, but aromatase inhibitors, including letrozole, might result in better pregnancy outcomes. METHODS In this double-blind, multicenter trial, we randomly assigned 750 women, in a 1:1 ratio, to receive letrozole or clomiphene for up to five treatment cycles, with visits to determine ...
OBJECTIVE To evaluate, retrospectively, the roles of endogenous and exogenous luteinising hormone (LH) activity on live birth rate in ovulation induction cycles. METHODS Associations between LH activity at baseline, end of stimulation and live birth rate were analysed in relation to patient characteristics, baseline and end of stimulation variables in WHO group II anovulatory women (n = 155) ...
CONTEXT To maximize birth rates, physicians who perform in vitro fertilization (IVF) often transfer multiple embryos, but this increases the multiple-birth risk. Live-birth and multiple-birth rates may vary by patient age and embryo quality. One marker for embryo quality is cryopreservation of extra embryos (if embryos are set aside for cryopreservation, higher quality embryos may have been ava...
Sperm DNA damage has a negative impact on pregnancy rates following assisted reproduction treatment (ART). The aim of the present study was to examine the relationship between sperm DNA fragmentation and live-birth rates after IVF and intracytoplasmic sperm injection (ICSI). The alkaline Comet assay was employed to measure sperm DNA fragmentation in native semen and in spermatozoa following den...
OBJECTIVE To assess the efficiency of a "freeze-all" embryo strategy after immature oocyte retrieval (OR) and in vitro maturation (IVM) in patients with polycystic ovary syndrome (PCOS). DESIGN Retrospective case series. SETTINGS University-based tertiary referral center. PATIENT(S) Seventy-nine consecutive PCOS patients undergoing IVM followed by vitrified-warmed embryo transfer (ET) ove...
