Dr. Chih-Ting Chang

About

Dr. Chih-Ting Chang is Director of Reproductive Surgery at NUWA Fertility Center Taipei and a Ministry of Health and Welfare approved ART physician — the registration a physician in Taiwan needs in order to perform assisted reproduction procedures. NUWA describes the clinic as an approved assisted-reproduction institution, so the physician-level approval and the institution-level one sit under the same roof.

Medical training came from Fu Jen Catholic University’s School of Medicine. Postgraduate work took place at Kaohsiung Medical University Chung-Ho Memorial Hospital, in the obstetrics and gynaecology department’s reproductive division, first as a resident physician and then as attending physician in the same unit. In Taiwan that progression through a university hospital’s reproductive division is the main supervised path toward specialist practice in assisted reproduction, and it covers stimulation protocols, endocrine workup and the surgical side of the field rather than one of them alone.

Care spans three modes of treatment at once: medication-led (IVF, IUI, ovulation induction in PCOS), laboratory-adjacent decision-making (PGT-A and PGD), and operative work (hysteroscopic surgery, management of endometriotic cysts, adenomyosis and fibroids). Structure-bound disease sits alongside hormonal causes rather than being delegated elsewhere.

Clinical Expertise

• Fertility preservation for cancer patients (oncofertility): arranging egg, embryo or sperm freezing before chemotherapy, radiotherapy or surgery, so the patient can use own gametes later. The timing has to be negotiated with the oncology schedule, which compresses the window for stimulation and retrieval.
• IVF and IUI: protocol design and cycle execution at two different levels of intervention, chosen against diagnosis, age and ovarian reserve.
• PGT-A and PGD: PGT-A screens embryos for chromosome number, used with advanced maternal age, repeated failure or recurrent loss; PGD tests for a specific known single-gene condition in couples trying to avoid passing it on. Different indications, different lab workflow, different counselling.
• Egg freezing: vitrification for patients deferring pregnancy, medical or otherwise.
• Premature ovarian failure, menstrual irregularity and endocrine disorder: assessment of ovarian reserve and hormonal status, addressing the endocrine reasons a cycle will not progress.
• Recurrent pregnancy loss: systematic review across embryo chromosome status, uterine cavity anatomy, endocrine factors and immune contribution, then a changed strategy for the next attempt rather than a repeat of the last one.
• Endometriotic cysts (chocolate cysts) and adenomyosis: both affect egg recruitment and implantation, and both require weighing what surgery can improve against what it costs in ovarian tissue.
• Uterine fibroids: position and size judged against cavity shape and pregnancy outcome, before deciding whether to operate.
• Hysteroscopic surgery: entering through the cervix to remove polyps, adhesions, submucosal fibroids and correct cavity shape, which is the step that prepares the transfer environment.
• PCOS: managing the wide individual variation in response to ovulation induction, and the ovarian hyperstimulation risk that comes with it.

Why Choose Dr. Chang

The ART physician approval, held in plain terms. In Taiwan the right to run assisted reproduction procedures is administered by the Ministry of Health and Welfare, and a clinic description can convey nothing more than a job title. Dr. Chang holds the approval itself, at a clinic NUWA describes as an approved assisted-reproduction institution.

Oncofertility as a stated commitment, not an implication. Fertility preservation before cancer treatment is one of the more coordination-heavy parts of reproductive medicine: the stimulation and retrieval have to fit inside the interval before oncology therapy starts, and the laboratory has to be ready for the material on a date someone else controls. Egg freezing for cancer patients and egg freezing in general are both part of this practice, and the former Supervisory Board role at the Taiwan Academy of Tumor Ablation connects the two.

Both PGT-A and PGD in one consultation. Count screening and single-gene diagnosis are separate questions with different eligibility, different biopsy targets and different cost, and a patient deciding between them — or deciding neither applies — gets a clearer answer from a physician who works in both.

Continuous training in one academic reproductive unit. Resident physician followed by attending physician at Kaohsiung Medical University Chung-Ho Memorial Hospital means the supervised years and the independent years were spent in the same department, with the same case mix and the same protocols.

Professional Affiliations

Membership of the Taiwan Society for Reproductive Medicine, with a term on the Supervisory Board of the Taiwan Academy of Tumor Ablation and membership of the Taiwan Association for Minimally Invasive Gynecology. The first of these is the specialty society for reproductive medicine in Taiwan; the third matches the hysteroscopic and operative side of the practice.

Dr. Chang studied at Fu Jen Catholic University’s School of Medicine, earning a Bachelor’s Degree, then trained and practised as resident physician and subsequently attending physician in the Reproductive Division of the Department of Obstetrics and Gynaecology at Kaohsiung Medical University Chung-Ho Memorial Hospital. The Ministry of Health and Welfare ART physician approval belongs to the same professional history.

Suitable For

Cancer patients needing fertility preservation before treatment: chemotherapy and radiotherapy can damage ovarian reserve and sperm production, and the work has to be finished before therapy begins. The oncofertility practice plus the tumor ablation society role map onto the scheduling negotiation this requires.

Premature ovarian failure or endocrine and menstrual disorder: falling reserve or an irregular cycle changes both the protocol and the expectation, so hormone status and follicle count come before any decision about stimulation.

Recurrent pregnancy loss needing a re-planned cycle: causes spread widely enough that repeating the previous approach does not reliably improve the outcome. Recurrent loss and PGT-A are both part of this practice, which makes screening one option inside the workup rather than an outside referral.

Endometriotic cysts or adenomyosis alongside infertility: each case turns on the trade between surgical improvement and tissue loss. Endometriosis, adenomyosis and hysteroscopic surgery are covered by one physician, so the decision can be argued within one assessment instead of across three consultations.

Couples deciding between PGT-A and PGD: advanced age, repeated failure or a known inherited condition each point somewhere different, and the choice shifts both the timeline and the cost of the cycle.
