The Creighton Model FertilityCare System (Creighton Model, FertilityCare, CrMS) is a form of natural family planning which involves identifying the fertile period during a woman's menstrual cycle. The Creighton Model was developed by Thomas Hilgers, the founder and director of the Pope Paul VI Institute .
The technique, first attempted by Steptoe and Edwards [1] and later pioneered by endocrinologist Ricardo Asch, allows fertilization to take place inside the woman's uterus. [ 2 ] With the advances in IVF the GIFT procedure is used less as pregnancy rates in IVF tend to be equal or better and do not require laparoscopy when the egg is put back.

[29] Assisted reproductive technology procedures performed in the U.S. has over than doubled over the last 10 years, with 140,000 procedures in 2006, [30] resulting in 55,000 births ...
The World Health Organization considers the rhythm method to be a specific type of calendar-based method, and calendar-based methods to be only one form of fertility awareness. [2] More effective than calendar-based methods, systems of fertility awareness that track basal body temperature, cervical mucus, or both, are known as symptoms-based ...
The effectiveness of fertility awareness, as of most forms of contraception, can be assessed two ways. Perfect use or method effectiveness rates only include people who follow all observational rules, correctly identify the fertile phase, and refrain from unprotected intercourse on days identified as fertile.
A woman's fertility is affected by her age. The average age of a girl's first period is 12–13 (12.5 years in the United States, [4] 12.72 in Canada, [5] 12.9 in the UK [6]), but, in postmenarchal girls, about 80% of the cycles are anovulatory in the first year after menarche, 50% in the third and 10% in the sixth year.

The first activated embryo by ICSI was produced in 1990, [15] but the first successful birth by ICSI took place on January 14, 1992, after an April 1991 [16] conception. [ 17 ] Sharpe et al comment on the success of ICSI since 1992 saying, "[t]hus, the woman carries the treatment burden for male infertility, a fairly unique scenario in medical ...
In vitro fertilisation (IVF) is a process of fertilisation in which an egg is combined with sperm in vitro ("in glass"). The process involves monitoring and stimulating a woman's ovulatory process, then removing an ovum or ova (egg or eggs) from her ovaries and enabling a man's sperm to fertilise them in a culture medium in a laboratory.
