PCOS can make fertility treatment look deceptively straightforward. Many people with polycystic ovary syndrome produce a high number of follicles during stimulation, so IVF cycles may retrieve plenty of eggs. Yet the final outcome can still be uncertain because egg maturity, embryo quality, implantation, miscarriage risk, and metabolic health all sit in the same equation. That is where the IVF versus ICSI question becomes more complex. Intracytoplasmic sperm injection, or ICS

A human embryo can look “good” under the microscope and still fail to implant. Another may appear less perfect yet lead to a healthy birth. This gap between appearance and outcome is one of the hardest problems in in-vitro fertilisation, and it is why embryologists keep searching for visible, non-invasive clues that tell us more about embryo potential. One of the more intriguing clues is the presence of cytoplasmic strings, also called cytoplasmic threads or cellular bridges,

A positive pregnancy test after a fresh embryo transfer brings relief, but it also brings close monitoring. If a doctor then mentions a “decidual polyp”, the term can sound alarming. In many cases, it describes a pregnancy-related change in a cervical or endometrial polyp rather than a cancerous or aggressive condition. Still, in assisted reproduction, even small findings can matter because early pregnancy is already under careful observation. Decidual polyps sit at the inter

Infertility is often discussed through hormones, ovulation, age, and reproductive organs. A growing body of research suggests another player deserves attention: low-grade inflammation linked with blood lipids, especially high-density lipoprotein, commonly known as HDL.

The placenta grows in a narrow biological window. Too little oxygen, too much oxygen, or the wrong oxygen signal at the wrong time can alter how trophoblast cells invade, remodel maternal blood vessels, and support fetal growth. In pregnancies conceived through assisted reproductive technologies, this oxygen-sensitive programme has particular clinical relevance because implantation, early placentation, embryo culture, ovarian stimulation, and endometrial preparation may all i

Oocyte donation is often described in medical terms, but the decision to donate is deeply human. It can involve generosity, money, grief, curiosity, family history, and a careful weighing of personal risk. For some donors, it feels like a meaningful way to help someone build a family. For others, it is also a practical financial choice. Many hold both feelings at once. That mix matters. When clinics, counsellors, recipients, and policymakers understand why people donate, they

In vitro fertilization (IVF) has transformed the possibilities for couples facing infertility. Yet, the protocols used to stimulate the ovaries remain a critical factor in treatment success and patient experience. Orvieto R.'s recent study on the Stop GnRH-agonist/GnRH-antagonist protocol offers fresh insights into ovarian stimulation, challenging traditional approaches and opening new avenues for IVF care. This post explores the key findings of the study, compares the new pr

Ovarian hyperstimulation syndrome (OHSS) remains a significant concern in fertility treatments, especially for women undergoing assisted reproductive technologies like in vitro fertilization (IVF). This condition can cause serious complications, ranging from mild discomfort to life-threatening symptoms. Recent research by Elia EM et al. sheds light on how metformin, a common medication primarily used for diabetes, might reduce the risk and severity of OHSS. This blog post exp

Polycystic Ovary Syndrome (PCOS) affects millions of women worldwide, yet its diagnosis and management have often been inconsistent. The 2023 International Evidence-based Guideline for the Assessment and Management of PCOS offers a comprehensive update, aiming to improve care quality and patient outcomes. This blog post summarizes the key findings and recommendations from this guideline, highlighting practical implications for healthcare providers and patients alike. Insights

Polycystic ovary syndrome (PCOS) affects millions of women worldwide, presenting a complex challenge for both patients and healthcare providers. This hormonal disorder disrupts normal ovarian function and leads to symptoms such as irregular menstrual cycles, excess androgen levels, and metabolic issues. Among the various treatment options, metformin has gained attention for its potential to improve both metabolic and reproductive outcomes in women with PCOS. This article expl

Assisted reproductive technology (ART) has transformed the landscape of fertility treatments, offering hope to many couples facing challenges in conceiving. Among the many factors influencing ART success, the role of medications administered during the peri-implantation phase—the critical window when an embryo attaches to the uterine lining—has drawn increasing attention. A recent study by Boomsma et al. sheds light on how glucocorticoids, a class of steroid hormones, affect

Luteal phase support plays a crucial role in the success of frozen-thawed embryo transfer (FET) cycles. The study by Zareii et al. explores an important question in reproductive medicine: does adding gonadotropin-releasing hormone (GnRH) agonists to vaginal progesterone improve outcomes in FET cycles? This post examines the study’s objectives, methods, key findings, and their implications for clinical practice. We also compare the effectiveness of combined treatment versus va

In assisted reproductive technologies like IVF (in vitro fertilization) and ICSI (intracytoplasmic sperm injection), the luteal phase plays a crucial role in embryo implantation and pregnancy success. While progesterone has long been recognized as essential for luteal phase support (LPS), the role of estrogen during this phase is gaining attention. This post explores the significance of estrogen as luteal phase support, differences in its effects on normal versus poor respond

Assisted reproductive technology (ART) continues to evolve, offering hope to many couples facing infertility. One critical aspect of ART success is luteal phase support (LPS), which helps prepare the uterus for embryo implantation. The recent study by Greenbaum et al. sheds new light on how luteal phase support affects outcomes in fresh and frozen embryo transfers. This blog post explores the key findings of their research, the importance of luteal phase support, differences

Embryo transfer marks a critical step in assisted reproductive technology (ART), yet many factors influence its success. One procedure gaining attention is diagnostic hysteroscopy before the first embryo transfer. This minimally invasive technique allows direct visualization of the uterine cavity, potentially identifying abnormalities that could affect implantation and pregnancy outcomes. A recent retrospective study by Fang JY et al sheds light on the value of this approach,

In vitro fertilization (IVF) offers hope to many couples facing infertility, but success rates remain a challenge. One intervention that has attracted attention is endometrial injury, sometimes called "endometrial scratching," which involves intentionally causing a small injury to the uterine lining before embryo transfer. The idea is that this injury might improve the chances of embryo implantation and pregnancy. The 2021 Cochrane review by Lensen et al. provides a comprehen

Embryo transfer is a critical step in assisted reproductive technology (ART), directly influencing the success rates of in vitro fertilization (IVF). The technique used during embryo transfer can affect implantation and pregnancy outcomes. A meta-analysis by Sallam HN and Sadek SS examined the role of ultrasound guidance during embryo transfer and its impact on fertility treatment success. This blog post explores their findings, summarizes the randomized controlled trials (RC

In vitro fertilization (IVF) remains a cornerstone of assisted reproductive technology, yet success rates vary widely. One procedural step that has drawn attention is the mock embryo transfer (MET), performed before the first IVF cycle to simulate the actual embryo transfer. The randomized controlled trial by Borkar A, Shah A, Gudi A, and Homburg R offers valuable insights into how MET influences IVF outcomes. This article examines their study’s methodology, key findings, and
