Does the process of embryo implantation during the daytime in Ramadan invalidate the fast, and is expiation due for that day?

Artificial insemination is the fertilization of a woman's egg with a man's sperm without intercourse. This can be internal, by injecting sperm into the uterus, or external (IVF), by taking the sperm and egg, fertilizing them in a tube, and then transferring them to the uterus.

Regarding its effect on fasting: 1. Taking sperm from a man through masturbation during the day in Ramadan is considered a fast-breaker by the majority of scholars and must be avoided. 2. Taking an egg from a woman for external insemination is not considered a fast-breaker. 3. Introducing a man's semen into a woman's vagina via a catheter is not considered a fast-breaker, as it is neither eating nor drinking. The vagina is not connected to the digestive system, and what enters the vagina is not considered a fast-breaker, according to the resolution of the Islamic Fiqh Academy. Moreover, this insertion is not considered intercourse that would necessitate ghusl (ritual purification) for the woman.

Based on this, the process of artificial insemination and embryo implantation does not invalidate a woman's fast. However, it is preferable to avoid this in Ramadan if possible, to preserve the fast and distance oneself from doubt.
