Ms. Zhang, from Shanghai, 35, a mid-level manager at Apple, frequently travels between Shanghai and California.

As she grew older without meeting the right person, she realized that if she didn't have a child soon it would only get harder. With her family's support, she decided to have a child on her own. lelaiwa advised her to plan her time well and, between work commitments, undergo egg retrieval and transfer at a California fertility clinic.

After smooth pre-checks, she stimulated and retrieved 14 healthy eggs, using donor sperm from a U.S. sperm bank. Through the clinic's embryo culture, 7 blastocysts were formed, 4 of which passed PGS screening — 3 boys and 1 girl among the 4 healthy embryos. Ms. Zhang was especially happy, as she wanted a boy first and a girl later. The transfer went smoothly; she gave birth to a baby boy and enjoyed the wonderful experience of motherhood.

For a woman wanting a baby, it is truly hard work, but the process gave me a very different life, a different experience, and a fulfilling sense of life — well worth doing. — Ms. Zhang
