When considering assisted reproduction treatments, the two most common options are Artificial Insemination (AI) and In Vitro Fertilization (IVF). Although both aim to achieve pregnancy, their success rates and complexity levels differ greatly. Below we break down their differences so you can make the best decision for your situation. Quick takeaway: IVF usually offers higher success rates and is the ideal choice if you want to maximize your chances. What is AI and how does it work? Artificial Insemination (AI) is a low-complexity procedure. It involves placing processed sperm (0.5–1 mL) into the uterine cavity during ovulation to facilitate fertilization. It’s perfect for couples with mild infertility or single women desiring motherhood. Never self-medicate: always consult a specialist. Types of AI Intravaginal (IV): sperm placed near the cervix. Intracervical (IC): deposited in the cervical canal. Intrauterine (IU): the most common: direct injection into the uterus. Tuboperitoneal (TP): a mix of uterine and peritoneal deposition. Intratubal (IT): placed in the fallopian tube. Intrafollicular (IF): injected into ovarian follicles. Who can benefit? Women under 35 with good ovarian reserve, couples with mildly reduced sperm motility, or those seeking a less invasive option. Success rates range from 10% to 20% per cycle in women under 35 and decrease with age or additional factors. What is IVF and why consider it? In Vitro Fertilization (IVF) is an advanced treatment with over 40 years of development. Eggs and sperm are fertilized in the lab, the best embryos are selected, and genetic testing can be performed if needed. Its success rates far exceed those of AI. Steps of IVF Ovarian stimulation: gonadotropin injections to produce multiple follicles. Egg retrieval: ultrasound-guided aspiration under sedation. Fertilization: eggs and sperm combined in culture medium. Embryo culture: 3–5 days monitored in an incubator. Transfer: placement of 1–2 embryos into the uterus. Ideal candidates Blocked fallopian tubes Endometriosis Polycystic ovary syndrome (PCOS) Poor sperm quality Advanced maternal age (35+) Consult a reproductive specialist before making any decisions. Comparison: AI vs. IVF Invasiveness: AI is minimal; IVF involves injections, retrieval, and transfer. Success rates: AI 10%–20% per cycle (
