[10] Pregnancy test: after two weeks, a period known as the two-week wait it can be determined if the embryos had been properly implanted and will result in a pregnancy. [11]
This is possibly because gestational carriers tend to be healthier and more fertile than women who use oocyte donation. Gestational carriers also have low rates of placenta previa / placental abruptions (1.1–7.9%). [12]
A pregnancy may end in a live birth, a miscarriage, an induced abortion, or a stillbirth. Childbirth typically occurs around 40 weeks from the start of the last menstrual period (LMP), a span known as the gestational age. [4] [5] This is just over nine months.

In order to optimise pregnancy rates, there is significant evidence that a morphological scoring system is the best strategy for the selection of embryos. [14] Since 2009 where the first time-lapse microscopy system for IVF was approved for clinical use, morphokinetic scoring systems has shown to improve to pregnancy rates further. [15]
Pregnancy rate is the success rate for getting pregnant.It is the percentage of all attempts that leads to pregnancy, with attempts generally referring to menstrual cycles where insemination or any artificial equivalent is used, which may be simple artificial insemination (AI) or AI with additional in vitro fertilization (IVF).
According to a study from 2021, lesbian women undergoing IUI had a clinical pregnancy rate of 13.2% per cycle and 42.2% success rate given the average number of cycles at 3.6. [33] IUI has been reported to be more effective than ICI [ 34 ] [ 35 ] but this has been contested with some citing no strong evidence to confirm a significant difference ...
