On the other hand, in women who have had previous unsuccessful treatment, IVF achieves a live birth rate approximately 2–3 times greater than ovarian stimulation combined with IUI. [8] IUI and ICI has higher pregnancy rates when combined with ovarian stimulation in couples with unexplained infertility, for IUI being 13% unstimulated and 15% ...
Recurrent IVF failure is a much more broad term and includes all repeated failures to get pregnant from IVF. Repeated implantation failure specifically refers to those failures due to unsuccessful implanting to the uterus wall. [1] An unsuccessful implantation can result from problems with the mother or with the embryo.
IUI is an economic option for same-sex couples and can be done without the use of medication. [36] According to a study from 2021, lesbian women undergoing IUI had an average clinical pregnancy rate of 13.2% per cycle and 42.2% success rate giving the average number of cycles at 3.6. [37]
Thus, if a clomiphene treatment has a chance to establish a pregnancy in 8% of cycles and costs $800, the expected cost is $9,700 to establish a pregnancy, compared to an IVF cycle (cycle fecundity 40%) with a corresponding expected cost of $48,300 ($19,300 × 40%). [citation needed]
A first-of-its-kind case study has highlighted the ways in which the brain changes throughout pregnancy, including decreases in gray matter volume, and increases in white matter.
For optimal pregnancy chance, there are recommendations of sexual intercourse every 1 or 2 days, [14] or every 2 or 3 days. [15] Studies have shown no significant difference between different sex positions and pregnancy rate, as long as it results in ejaculation into the vagina . [ 16 ]
The World Health Organisation also adds that 'women whose pregnancy spontaneously miscarries, or whose pregnancy results in a still born child, without ever having had a live birth would present with primarily infertility'. [16] Secondary infertility is defined as the difficulty in conceiving a live birth in couples who previously had a child. [16]
When used to avoid pregnancy, the standard days method has been estimated [22] to have perfect-use efficacy of 95% and typical-use efficacy of 88%. [ 20 ] [ 21 ] These figures are based on a 2002 study in Bolivia, Peru, and the Philippines of women of reproductive age having menstrual cycles between 26 and 32 days, [ 20 ] [ 23 ] : 505 and on a ...
