if one ovary releases an egg for the first pregnancy the other ovary release it for the next pregnancy or only the first one will be release

Typically, each ovary takes turns releasing eggs on alternate menstrual cycles. The release of eggs from the ovaries is known as ovulation. However, it is possible for both ovaries to release an egg during the same cycle, resulting in a possibility of fraternal twins.

During pregnancy, ovulation does not occur as the body prepares for the development of a fertilized egg rather than releasing new eggs. Therefore, in subsequent pregnancies, it is not the ovary's turn to release an egg.

It's important to note that there can be variations and exceptions to this pattern, as every woman's reproductive system is unique. Consultation with a healthcare professional can provide more specific information based on an individual's circumstances.

Each ovary is capable of releasing an egg for fertilization during a woman's reproductive years. During each menstrual cycle, one ovary may release an egg, while the other remains dormant. The ovary that releases the egg can alternate each month. So, if one ovary releases an egg for the first pregnancy, it is entirely possible for the other ovary to release an egg for a subsequent pregnancy. The release of eggs from the ovaries is not limited to just the first pregnancy.

During a woman's reproductive years, she typically has two ovaries - one on each side of the uterus. Each ovary contains multiple immature eggs, called follicles. Each menstrual cycle, one dominant follicle develops and is released from one of the ovaries. This process is called ovulation.

In general, only one ovary releases an egg during each menstrual cycle. The ovaries do not take turns releasing eggs from one cycle to another. Once the egg is released, it travels through the fallopian tube and into the uterus. If the egg is fertilized by sperm, it may result in a pregnancy.

It's important to note that after an egg is released, the remaining follicles in both ovaries undergo a process called atresia, which essentially involves the shrinking and re-absorption of those follicles. Therefore, once an egg is released from an ovary, it does not get replaced by another egg in the same menstrual cycle.

However, during subsequent menstrual cycles, the other ovary has the opportunity to release an egg if it develops a dominant follicle. Each ovary has the potential to release eggs independently in different cycles, depending on various factors such as hormonal balance and ovarian function.

So, in conclusion, each ovary has the potential to release an egg, but typically only one ovary releases an egg during each menstrual cycle.
