National trends and outcomes of autologous in vitro fertilization cycles among women ages 40 years and older

Abstract

The NASS allows for a comprehensive description of IVF cycles in women ≥40 years in the USA. Although live birth rate is less than 20%, identifying factors associated with IVF success can facilitate treatment option counseling.

Subfertility: philosophy and methodology of the problem. Part II

“…Напротив, уровень антимюллерова гормона в плазме крови выше 0,8 нг/мл в сочетании с наличием не менее пяти в одном или как минимум шести антральных фолликулов диаметром более 5 мм в обоих яичниках сохраняет надежду на успех при проведении контролируемой гиперстимуляции яичников и ОИВ [109,110]. В начале обследования тактически правильным будет изучение овуляции, особенностей формирования овуляторной стигмы, размеров овулирующего фолликула и желтого тела, а также соответствия структуры эндометрия стандартам нормы.…”

Effectiveness of seminal plasma in in vitro fertilisation treatment: a systematic review and meta‐analysis

“…With in vitro fertilization (IVF) techniques, only 20–25% of the transferred embryos lead to a pregnancy . Besides embryo quality, endometrial receptivity plays an important role in the establishment of a pregnancy .…”

“…With in vitro fertilization (IVF) techniques, only 20–25% of the transferred embryos lead to a pregnancy . Besides embryo quality, endometrial receptivity plays an important role in the establishment of a pregnancy . Around implantation, a feto–maternal dialogue and a unique state of maternal immune tolerance is needed to avoid an immune attack on the implanting and developing semi‐allograft conceptus .…”

“…Endometrial function is highly sensitive to a number of factors including supraphysiological concentrations of estrogen in conventional gonadotropin‐stimulated IVF. Accordingly, several studies have revealed functional alterations of the endometrium in IVF therapies, including endometrial immune cell signaling …”

“…Seminal plasma (SP), fluid without sperm, has been shown to stimulate the expression of pro‐inflammatory cytokines in vivo in animal studies and in humans in vitro . SP and semen have therefore been suggested to support implantation through their beneficial effects on endometrial function and the maternal immune system .…”
