Tandem Cycle

Tandem Cycle

Tandem Cycle, which gives women the opportunity to use their own eggs as well as healthy eggs donated for pregnancy, is an important technique especially for women with reduced egg number and quality or for women of advanced age. In tandem treatment, the mother candidate and the donor are prepared at the same time and both eggs (mother candidate and surrogate) are fertilized with the sperm of the couple’s male partner. Finally, the better developed embryos of the two are transferred to the mother.

Many expectant mothers can be sensitive and indecisive at the stage of consenting to this procedure. With an advanced tandem IVF cycle that guarantees to reach healthy embryos by the use of donor eggs is recommended as an effective method, when the patient’s eggs fail. Tandem IVF cycle, which is applied in very few clinics in the world, guarantees a high success rate thanks to the opportunity it offers in selecting embryos by our expert staff and complete infrastructure in our clinic.

FSH supports the growth and development of follicles in the ovaries. These follicles produce the hormone estrogen. The hormone estrogen promotes the thickening of the endometrium (the inner lining of the uterus) and the maturation of the egg.

The LH hormone starts the ovulation process. During this process, the matured egg is released from the follicle and moves towards the fallopian tube. Under the influence of the LH hormone, the follicle turns into corpus luteum. Corpus luteum prepares the endometrium for pregnancy by producing progesterone hormone.

If pregnancy does not occur, the corpus luteum regresses and progesterone levels decrease. In this case, the upper layer of the endometrium is shed and menstruation occurs. The Tandem cycle begins again and a new follicle begins to mature.

The balance of the Tandem Cycle is affected by many factors, including nutrition, stress, hormonal disorders and age. Therefore, understanding the Tandem Cycle is of great importance in matters such as fertility planning and birth control.
