A 39-year-old woman from Guangzhou, after four failed IVF cycles in mainland China, traveled to Hong Kong Sanatorium & Hospital for treatment. A comprehensive review revealed that none of her previously transferred embryos had undergone chromosomal screening. In the new cycle, PGT-A was applied — of 5 blastocysts, only 2 were chromosomally normal. Transfer of one normal embryo resulted in a successful pregnancy. Centering on this narrative, the article systematically analyzes the five major causes of recurrent IVF failure (embryonic chromosomal abnormalities, uterine environment, immune factors, sperm quality, and laboratory conditions), introduces Hong Kong's advantages in PGT application, advanced embryology laboratories, and personalized protocol adjustments, explains the principles and indications of PGT-A technology, compares major reproductive medicine centers in Hong Kong, and provides a complete treatment pathway and practical recommendations for patients seeking treatment in Hong Kong.

Gender-affirming hormone therapy and certain surgical procedures may temporarily or permanently affect sperm production, egg production and the ability to carry a pregnancy. Fertility should ideally be assessed and preserved before treatment. Transgender women commonly consider sperm freezing, while transgender men may consider egg freezing. Intersex people require an individual assessment based on their reproductive anatomy and hormone function. The Chinese mainland imposes substantial eligibility restrictions on egg freezing and subsequent assisted reproduction for unmarried people. The Hong Kong Special Administrative Region of China generally permits unmarried people to retrieve and store gametes, although their future use remains subject to applicable rules. Kyrgyzstan and Thailand may be considered as additional overseas options.

Gay male family building normally requires sperm, donor eggs, IVF and a gestational carrier. Surrogacy cannot lawfully be performed by medical institutions in mainland China, while Hong Kong’s current framework is generally unsuitable for male same-sex couples. Kyrgyzstan offers integrated fertility, egg-donation, embryo and pregnancy-related services and may be considered a priority destination. Thailand provides advanced reproductive medicine and an LGBT-friendly environment and may be evaluated for fertility assessment, sperm or embryo preservation and future treatment options.

Mainland China and Hong Kong impose marriage-based restrictions on assisted reproduction, so lesbian couples generally cannot access donor insemination, donor-sperm IVF or reciprocal IVF locally. Overseas options may include donor insemination, donor-sperm IVF and reciprocal IVF, but medical access does not automatically give both partners legal parenthood. Before choosing Kyrgyzstan or Thailand, confirm clinic licensing, donor rules, parentage, birth registration and travel-document arrangements. Surrogacy is usually unnecessary if one partner can safely carry the pregnancy.

Mainland China generally does not provide single women with artificial insemination, IVF, or elective egg freezing. Hong Kong permits single women to consult licensed centres about egg retrieval and storage, but they normally cannot use donor sperm for fertilisation and embryo transfer while unmarried. The United Kingdom, Spain, Canada, and certain other jurisdictions offer donor-sperm IUI, IVF, or egg freezing to eligible single women. Surrogacy is usually unnecessary when a woman has a healthy uterus and can safely carry a pregnancy. Any arrangement involving surrogacy, cross-border parentage, or birth registration requires a separate legal assessment.

Starting with a real case of a 34-year-old Shenzhen patient with congenital bilateral absence of the vas deferens (CBAVD) causing obstructive azoospermia, who successfully achieved biological parenthood through TESE surgery and ICSI at Hong Kong Sanatorium & Hospital, this article systematically covers: the classification and etiology of obstructive azoospermia, the principles of MESA/TESE surgical sperm retrieval and ICSI technology in Hong Kong, the required documents and complete process for mainland patients seeking treatment in Hong Kong, major reproductive medicine centers in Hong Kong, cost comparisons between public and private hospitals, legal provisions regarding surrogacy, and practical recommendations. The entire article centers on the theme of achieving biological parenthood through surgical sperm retrieval combined with ICSI, providing clear decision-making references for mainland patients considering treatment in Hong Kong.

Starting with a real case of a 38-year-old patient with severe oligoasthenoteratozoospermia who successfully achieved parenthood through ICSI, this article systematically covers: the definition and diagnostic criteria of oligoasthenoteratozoospermia, the principle of second-generation IVF (ICSI) technology and its differences from conventional IVF, the indications and success rates of ICSI, a comparative overview of ICSI services and costs at major reproductive medicine centers in Hong Kong, the complete treatment process, and practical advice for patients. The entire article revolves around the central theme of male infertility patients realizing their dream of parenthood through ICSI technology, providing clear decision-making references and action guides.

This article addresses the real-world challenges faced by older women in Hong Kong dealing with declining ovarian function. Starting with an explanation of AMH as a key indicator of ovarian reserve and its interpretation, it presents a real case of a 42-year-old woman who successfully conceived through a mild-stimulation IVF protocol. The article systematically covers: when older women in Hong Kong should undergo fertility assessments, the range of fertility options available when AMH is low, the role of IVF (particularly PGT-A / third-generation IVF) for advanced maternal age, a comparative overview of Hong Kong's major reproductive medicine centers with their success rates and cost ranges, and the legal framework governing surrogacy in Hong Kong. The guide aims to provide clear, actionable decision-making support for older women facing diminished ovarian reserve.

Ovulation disorders may result from PCOS, hyperprolactinaemia, thyroid dysfunction, hypothalamic factors, or diminished ovarian reserve. Treatment generally begins by identifying and correcting the underlying cause, followed by ovulation induction where appropriate. IVF may be considered after repeated ovulation induction or intrauterine insemination has failed, particularly when age or additional infertility factors are involved. Before IVF, ovarian reserve, uterine health, semen quality, and general medical fitness should be assessed. Success is influenced mainly by age, egg and embryo quality, and accompanying infertility factors. An isolated ovulation disorder does not normally require surrogacy. Commercial surrogacy is prohibited in Hong Kong, while non-commercial arrangements remain subject to strict medical, licensing, and parentage requirements.

Gamete transport disorders occur when blocked, absent, fluid-filled, damaged, or adherent fallopian tubes prevent sperm and egg from meeting normally or interfere with embryo transport to the uterus. The likelihood of natural conception depends on the severity of the tubal condition, age, ovarian reserve, uterine health, and semen quality. Mild or localised conditions may be managed with natural conception attempts, medication, or surgery. IVF may be considered when both tubes are completely blocked or absent, severe hydrosalpinx or extensive pelvic adhesions are present, or ectopic pregnancy has occurred repeatedly. A comprehensive fertility assessment should be completed before treatment, and patients in Hong Kong should choose an appropriately licensed reproductive technology centre.
