Pregnancy

Getting Pregnant
To get pregnant in ATLust, you must have Female and Fertile enabled. Your compatibility score with male characters will determine your overall chance of becoming pregnant. The closer your species is in relation to the partner, the higher the compatibility.

There is always a small amount of compatibility, even when at 0% compatibility.

The over all percentage will be proportionate to the various species the character may have. So a 50% Fox, 50% Cat, would only have 50% compatibility with a 100% fox.

Fertility
Female fertility is calculated based on the fertility cycle, health, and status modifiers such as feline ovulation, heat and the fertility enhancer item. The fertility cycle is based on time, with the beginning and ending of the cycle being the least fertile times.

Pregnancy chance
Pregnancy chance is calculated by female fertility, species compatibility of the sperm, the sperms potency and the volume of the sperm. The chance is calculated every server cycle (Every minute). Each cycle, the volume of the sperm is lowered (Based on compatibility), and thus the chance goes down. The amount/volume of sperm has minimal impact on pregnancy chance.

For preventing pregnancy, obviously the first steps would be having the male pull-out or use a condom. The female has several options too. The spermicide item works by dramatically lowering the amount of time sperm can exist in the womb. Birth control lowers the overall pregnancy chance. Using both of these items simultaneously can effectively reduce your pregnancy chance to 0.

Impregnation
Once a character becomes pregnant, all of the sperm in the womb is removed. There will not be any immediate notifications about becoming pregnant, but if the character was in heat, a notification that heat has ended early will be sent. The character has a "Known pregnancy" flag that is not set until a pregnancy test is used, or they reach 40% progress. Once the known pregnancy flag is set, the character will have a visible pregnancy status in the character info page and summary.

There is a small chance that a character can become impregnated with babies from different fathers if they were inseminated by multiple males. This chance is extremely high when using the "Knock-Up" item.

Pregnancies
Pregnancy info is revealed in stages. *Father info will not be revealed if the sperm was from an anonymous source, such as broken condoms, sperm bank or if the character was inseminated by multiple fathers of the same species. In such cases, a paternity test will need to be used. Those can be used at the same percentage at which father info is normally revealed (80%). Paternity tests can always be used after the child is born (In the Children list), and even when activated (In the relations area of the character info). However, only a single test needs to be used during pregnancy, even if there are multiple offspring. But after they're born, they have to be used on each child if one was not used during the pregnancy.

Fathers will receive notifications at the same time that the father of the pregnancy is determined. They will also receive notifications when the mother gives birth.

Birth
Once a pregnancy reaches 100% progress, the mother gives birth and the children go into the children list. Currently, the birthing process does not require any action, and the mother and father are just sent notifications. The children will become visible in both the mother and fathers children list. Either parent can name the children, and use Growth-Spurt and activate the children (Activating a child turns them into a playable character). Anonymous fathers will not be able to do this unless a paternity test is used by the mother. If there are multiple fathers in the pregnancy, they will only see the children they fathered in their own Children list.
