A randomized controlled, non-inferiority trial of modified natural versus artificial cycle for cryo-thawed embryo transfer
Human reproduction (Oxford, England) ·doi:10.1093/humrep/dew120

STUDY QUESTION: Are live birth rates (LBRs) after artificial cycle frozen-thawed embryo transfer (AC-FET) non-inferior to LBRs after modified natural cycle frozen-thawed embryo transfer (mNC-FET)? SUMMARY ANSWER: AC-FET is non-inferior to …

Prevention of multiple pregnancies in couples with unexplained or mild male subfertility: randomised controlled trial of in vitro fertilisation with single embryo transfer or in vitro fertilisation in modified natural cycle compared with intrauterine insemination with controlled ovarian hyperstimulation
BMJ (Clinical research ed.) ·doi:10.1136/bmj.g7771

OBJECTIVES: To compare the effectiveness of in vitro fertilisation with single embryo transfer or in vitro fertilisation in a modified natural cycle with that of intrauterine insemination with controlled ovarian hyperstimulation in terms of…

Risk of borderline and invasive ovarian tumours after ovarian stimulation for in vitro fertilization in a large Dutch cohort
Human reproduction (Oxford, England) ·doi:10.1093/humrep/der322

BACKGROUND: Long-term effects of ovarian stimulation for IVF on the risk of ovarian malignancies are unknown. METHODS: We identified a nationwide historic cohort of 19,146 women who received IVF treatment in the Netherlands between 1983 an…

The addition of GnRH antagonists in intrauterine insemination cycles with mild ovarian hyperstimulation does not increase live birth rates--a randomized, double-blinded, placebo-controlled trial
Human Reproduction ·doi:10.1093/humrep/der033

BACKGROUND: This multicenter, double-blinded RCT investigated the efficacy of GnRH antagonists in cycles with mild ovarian hyperstimulation (MOH) followed by IUI in subfertile women. METHODS: Couples diagnosed with unexplained, male factor…

A randomized clinical trial of clomiphene citrate versus low dose recombinant FSH for ovarian hyperstimulation in intrauterine insemination cycles for unexplained and male subfertility
Human Reproduction ·doi:10.1093/humrep/del441

BACKGROUND: Controlled ovarian hyperstimulation with intrauterine insemination (IUI) is a widely accepted treatment for unexplained and male subfertility. No consensus exists about the drug of first choice to be used as hyperstimulation. Th…
