Dr. Hsin-Yi Ho

About

Two of Dr. Hsin-Yi Ho’s published studies ask questions about stimulation cycles rather than about cells in a dish: what an estradiol reading on day 9 of controlled ovarian hyperstimulation predicts about the risk of an over-response, and how an ovary that has already had an endometrioma removed responds to stimulation afterwards. Both appeared in the Journal of Assisted Reproduction and Genetics, and both describe decisions a physician makes at the monitoring ultrasound rather than in a laboratory. A further cycle-side paper addresses strict sperm morphology criteria as a prognostic factor in intrauterine insemination.

The doctorate itself is not in obstetrics or gynecology. It came from the Institute for Stem Cell Research at the University of Edinburgh, with research interests spanning reproductive endocrinology, embryology, developmental biology, embryonic stem cell biology and the in vitro neural differentiation of embryonic stem cells. Alongside it sits the medical degree from the School of Medicine at Taipei Medical University. Clinical years in Taipei ran through Mackay Memorial Hospital, where a trainee appointment was followed by an attending one in the reproductive endocrinology and infertility division, and then by attending work in the reproductive medicine and infertility department of Tai-An Hospital.

The current post is Deputy Medical Director of Reproductive Medicine at NUWA Fertility Center, where the practice runs from infertility diagnosis and reproductive endocrinology through IUI, IVF and egg freezing. NUWA names single embryo transfer separately rather than folding it into embryo transfer. Early-career publications in developmental biology — on the homeodomain protein Pitx3 in midbrain dopaminergic progenitors and in lens epithelial cells, and a review of embryonic stem cells as a route to cell therapy in Parkinson’s disease — sit underneath the reproductive work, together with a cross-sectional Taiwan study relating blood lead, cadmium and arsenic levels to female infertility risk factors.

Clinical Expertise

• Single embryo transfer: choosing to place one embryo rather than two, which trades a lower chance per transfer against the substantially higher maternal and fetal risk of a twin pregnancy. The clinic’s own patient story on this point documents a second child conceived after a single embryo was transferred.
• Controlled ovarian stimulation and IVF: writing the protocol, watching follicles on scan, timing the trigger and retrieval, and following the embryo through to transfer, with response risk read during monitoring rather than only explained after a poor cycle.
• IUI: induced ovulation paired with prepared semen placed into the uterus, positioned as the step before IVF, with semen morphology read as part of the decision on whether insemination is likely to work.
• Polycystic ovary syndrome: ovulation induction in patients whose response to medication varies widely between cycles, and where the hyperstimulation risk is highest.
• Reproductive endocrinology: hormone assessment and correction across ovulation, endometrial preparation and the metabolic conditions that sit behind anovulation.
• Egg freezing: vitrification for patients postponing pregnancy or facing treatment that can damage the ovaries, where the calendar is set by the other therapy rather than by the fertility plan.
• Infertility diagnosis and treatment: workup of both partners — ovulation, tubal patency, uterine cavity and semen analysis — before deciding which level of intervention the case needs.

Why Choose Dr. Ho

A stem cell doctorate behind a stimulation practice. Embryonic stem cell work and embryo handling share the same technical problems: culture conditions, timing of division, and whether a cell survives being frozen and thawed. A doctorate from an institute dedicated to that research, carried alongside a cycle-running practice, is the uncommon combination here, and research interests in reproductive endocrinology and embryology join the two directly.

Published on the specific questions a difficult cycle raises. Rather than general laboratory science, the reproductive work addresses hyper-response risk during stimulation and the poor response of ovaries previously operated for endometrioma. A third study, with Dr. Ho among the co-authors, tests strict sperm morphology criteria as a prognostic factor for insemination. Those are the points at which a plan usually has to change mid-cycle.

Society office at the executive level, twice. Dr. Ho has held Secretary-General and Vice Secretary-General of the Taiwan Society for Reproductive Medicine, plus a Vice Secretary-General term at the Taiwan Association of Obstetrics and Gynecology. These are executive positions inside the national bodies for the two specialties rather than membership lines.

One stated position on embryo number. Single embryo transfer is a named practice area in its own right, not an incidental choice, and the patient story NUWA publishes on the subject frames it explicitly as maternal and infant safety.

An English-language academic background. The Edinburgh doctorate and the international publications sit behind a practice whose cases include an overseas couple using donated eggs, and Dr. Ho also carries an assistant professorship designation at Mackay Junior College of Medicine, Nursing, and Management.

Professional Affiliations

Taiwan Society for Reproductive Medicine, served at both Secretary-General and Vice Secretary-General, and the Taiwan Association of Obstetrics and Gynecology at Vice Secretary-General. Both are national specialty bodies, one for reproductive medicine and one for obstetrics and gynecology. An assistant professorship was also designated at Mackay Junior College of Medicine, Nursing, and Management.

Degrees: Ph.D. from the Institute for Stem Cell Research, University of Edinburgh; M.D. from Taipei Medical University’s School of Medicine. Hospital appointments: trainee physician and then attending physician in the reproductive endocrinology and infertility division of Mackay Memorial Hospital, followed by the reproductive medicine and infertility department of Tai-An Hospital. Fourteen papers date from 1993 to 2015.

Suitable For

Infertility driven by PCOS and endocrine disorder: ovulation induction in this group needs dose adjustment against follicle response from scan to scan, because the same protocol can produce nothing in one cycle and an over-response in the next. Both PCOS and reproductive endocrinology are named specialties.

Deciding how many embryos to transfer: the question has a different answer for a first cycle with several good embryos than for a patient with one, and it turns on age, embryo quality and the obstetric risk of a multiple pregnancy. Single embryo transfer is a named practice area, so the number is a stated position rather than an assumption.

Gamete freezing before cancer treatment: preservation has to be scheduled against the date oncology therapy starts, which compresses the stimulation window and requires coordination with the treating team. Egg freezing is a named service, and NUWA publishes a case of sperm cryopreserved before chemotherapy and used ten years later.

Advanced age with poor stimulation response: fewer recruited follicles means every cycle is a decision about protocol, and about whether to keep stimulating or change route. The published work on hyper-response prediction and on previously operated ovaries addresses exactly this class of cycle planning.

English-speaking couples treated in Taipei: counseling, consent and laboratory reporting all cross a language line in a donor-egg or embryo-testing cycle. The Edinburgh doctorate and the publications are in English, and the patients treated here have included a Japanese couple using donated eggs.
