The rates of successful pregnancy for artificial insemination are 10-15% per menstrual cycle using ICI, [40] and 15–20% per cycle for IUI. [41] In IUI, about 60 to 70% have achieved pregnancy after 6 cycles.
IUI success rates depend on elements like sperm quality, timing of the procedure and age of the people involved, Wright says. However, success rates are usually quoted between 5% and 15% per cycle.
The time with the highest likelihood of pregnancy resulting from sexual intercourse covers the menstrual cycle time from some 5 days before until 1 to 2 days after ovulation. [10] In a 28‑day cycle with a 14‑day luteal phase, this corresponds to the second and the beginning of the third week. A variety of methods have been developed to help ...
An unsuccessful implantation can result from problems with the mother or with the embryo. It is essential that the mother and embryo are able to communicate with each other during all stages of pregnancy, and an absence of this communication can lead to an unsuccessful implantation and a further unsuccessful pregnancy.

The average user reports 16 days of bleeding or spotting in the first month of use, but this diminishes to about four days at 12 months. [51] [52] Cramping and pain: many women feel discomfort or pain during and immediately after insertion. Some women may have cramping for the first 1–2 weeks after insertion. [53]
Thus, if a clomiphene treatment has a chance to establish a pregnancy in 8% of cycles and costs $780, the expected cost is $9,400 to establish a pregnancy, compared to an IVF cycle (cycle fecundity 40%) with a corresponding expected cost of $46,800 ($18,700 × 40%). [citation needed]
In ovarian hyperstimulation combined with IUI, women aged 38–39 years appear to have reasonable success during the first two cycles, with an overall live birth rate of 6.1% per cycle. [12] However, for women aged ≥40 years, the overall live birth rate is 2.0% per cycle, and there appears to be no benefit after a single cycle of COH/IUI. [12]
Implantation bleeding occurs between 7 and 14 days after fertilization, [57] and is a small amount of light vaginal bleeding or spotting that can occur in early pregnancy due to the blastocyst penetrating the lining of the uterus during implantation.
