Ovarian tissue cryopreservation and transplantation is a formof fertility preservation offered to youngwomenathigh riskof losing ovarian function after cancer treatment.While therehavebeen successful births resulting fromorthotopic site grafts,we report the first caseof an ongoing pregnancy from a heterotopic graft in a patient who had previously undergone bilateral oopherectomy for a granulosa...

We start by showing that (1) is injective. Take an u ∈ Hom (A,B)⊗ Zl that maps to zero in HomΓ (Tl(A), Tl(B)). Write u = ∑∞ j=0 l uj , uj ∈ Hom(A,B), and [u]n for ∑n j=0 l uj . Note that since Hom (A,B) is a Z-module [u]n is in Hom (A,B). Now (since u maps to zero) [u]n is the zero morphism A[l ] → B[l], so it kills the ltorsion. As it is well known, this implies the existence of a certain ψn ∈...

BACKGROUND In both in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI), selection of the most competent embryo(s) for transfer is generally based on morphological criteria. However, many women fail to achieve a pregnancy after transfer of good quality embryos. One of the presumed causes is that such morphologically normal embryos show an abnormal number of chromosomes (aneu...

BACKGROUND The goal of this study was to assess the association between endometrial thickness on the chorionic gonadotropin (hCG) day and in vitro fertilization and embryo transfer (IVF-ET) outcome in normal responders after GnRH antagonist administration. METHODS A retrospective cohort study was performed in normal responders with GnRH antagonist administration from January 2011-December 201...

BACKGROUND General concern is that the pregnancy rate is higher with GnRH-agonist as a protocol of pituitary suppression. GnRH-antagonist protocol provides a shorter period of administration and an easy flexible protocol. OBJECTIVE In this study, the outcomes of GnRH agonist and antagonist in ICSI cycles are compared in normo responder patients. MATERIALS AND METHODS In this randomized clin...
