Explain howICSI is performed in the IVF lab, why it is used, what steps it involves, andwhat it can - and cannot - solve.

In this episode of Inside the IVF Lab, we focus on intra-cytoplasmic sperm injection, or ICSI - the micro-manipulation technique in which a single sperm isselected and injected directly into a mature oocyte. We explore why ICSI is used, how oocytes are denuded and assessed, how the injection dish and micromanipulators are set up, how sperm are immobilised and injected, and whattechnical or biologic factors can still limit success. This episode explainsone of the most precise and iconic procedures in modern embryology.

In this episode of Inside the IVF Lab, we focus on conventional IVF insemination - the standard fertilisation method in which prepared sperm are added to oocytes and allowed to fertilise without micro-manipulation. We explore when this method is used, how the lab prepares sperm and oocytes for co-incubation, what sperm must still do on their own to achieve fertilisation, and why failed fertilisation or abnormal fertilisation can still occur. This episode explains the biology and practical workflow behind one of the foundational techniques in assisted reproduction.

Before fertilisation can happen in the IVF lab, sperm must be carefully prepared. In this episode, we explore the andrology workflow: semen collection, sample identification, basic semen assessment, density gradient centrifugation, swim-up, sperm washing, and how samples are prepared differently for conventional IVF and ICSI. We also look at severe male factor cases, surgical sperm samples, and the limits of what sperm processing can achieve.

After eggs are recovered in the lab, the next question is not just how many were collected, but how many are actually mature and suitable for fertilisation. In this episode, we explore oocyte assessment in IVF: denudation, maturity staging, metaphase II identification, common morphologic features, and the limits of what embryologists can infer from egg appearance alone. This episode bridges the gap between retrieval and fertilisation by focusing on one of the most important cells in reproductive medicine.

A detailed walkthrough of what happens in the IVF lab during ovum pick-up, from receiving follicular fluid to recovering and preparing oocytes for fertilisation.

What does the embryologist actually do when eggs are collected? In this episode, we focus on ovum pick-up from the laboratory side: receiving follicular aspirates,identifying cumulus-oocyte complexes under the microscope, handling and washingoocytes, documenting recovery, and preparing them for insemination or ICSI.This episode unpacks one of the most time-sensitive and foundational steps inthe IVF lab.

A step-by-step guide to embryology, IVF lab techniques, and the science behind embryo creation.

What really happens inside the IVF lab? In this opening episode, we walk through the entire embryology journey - from ovum pick-up and sperm preparation to insemination,ICSI, fertilization checks, embryo culture, blastocyst development, freezing,and embryo transfer. This episode is designed as a full lab orientation, givinglisteners the big picture before later episodes unpack each technique indetail.
