Implantation in the lower half of the uterine cavity and decreased trophoblastic thickness can predict subsequent miscarriage: a prospective cohort study.

Abstract: Embryo implantation is vital for successful conception but remains to be fully understood. Trophoblast invasion is key for implantation, with anchorage and depth of placentation determined by its extent. There is a dearth of synchronous information regarding IVF, implantation site, and trophoblastic thickness (TT).

Hormone therapy for uterine and endometrial development in women with premature ovarian insufficiency.

Background: Premature ovarian insufficiency (POI) is a clinical syndrome resulting from loss of ovarian function before the age of 40. It is a state of hypergonadotropic hypogonadism, characterised by amenorrhoea or oligomenorrhoea, with low ovarian sex hormones (oestrogen deficiency) and elevated pituitary gonadotrophins. POI with primary amenorrhoea may occur as a result of chromosomal and genetic abnormalities, such as Turner syndrome, Fragile X, or autosomal gene defects; secondary amenorrhoea may be iatrogenic after the surgical removal of the ovaries, radiotherapy, or chemotherapy.

Emergency intrauterine device insertion in teenagers: an informal retrospective study.

Background: Widespread and increased availability of oral emergency contraception (EC) over the past 10 years has made little difference to rates of unintended pregnancy, abortion and repeat abortion amongst teenagers. The insertion of an intrauterine device for EC (EC-IUD) is 98-99% effective compared with 85% for oral methods and can be used for ongoing, long-term reversible contraception. However this method is seldom used for teenagers, a group with a high risk of unintended pregnancy, and there is little published data on the use of EC-IUD in this group.
