Fertility & IVF
In Vitro Fertilization (IVF)
In vitro fertilization (IVF) is the cornerstone of advanced reproductive medicine, designed to treat infertility—defined by the World Health Organization (WHO) as the failure to achieve pregnancy after 12 months or more of regular, unprotected intercourse. The procedure involves manually extracting eggs from an individual's ovaries, fertilizing them with sperm in a specialized laboratory setting, and transferring the resulting embryo directly back into the uterus to establish a pregnancy.
Key Indications: Why IVF is Performed
According to clinical overviews from the Mayo Clinic and NIH StatPearls, IVF is highly effective for treating several underlying causes of infertility:
Tubal Factors: Damaged, blocked, or completely missing fallopian tubes that prevent natural sperm-egg interaction.
Ovulation Disorders: Irregular or absent ovulation cycle issues, such as Polycystic Ovary Syndrome (PCOS).
Endometriosis: Severe uterine lining abnormalities affecting egg quality or pelvic anatomy function.
Severe Male-Factor Infertility: Significantly low sperm count, poor sperm motility, or structural blockages.
Unexplained Infertility: Persistent failure to conceive despite all standard diagnostic tests yielding completely normal results.
Advanced Maternal Age: Declining egg quantity and quality associated with being over the age of 35 to 40.
The Step-by-Step IVF Medical Process
The standard clinical journey of a single IVF cycle typically spans several weeks and involves high-precision medical milestones:
Ovarian Stimulation: Self-administered hormonal medications are taken for 8–12 days to stimulate the ovaries into growing multiple mature eggs.
Follicle Monitoring: Regular transvaginal ultrasounds and blood estrogen tests are performed to accurately track egg development.
Egg Retrieval: A minor surgical procedure performed under light sedation, where a thin, ultrasound-guided needle retrieves eggs directly from the ovarian follicles.
Fertilization (and ICSI): The retrieved eggs are combined with sperm in a petri dish. If male factor infertility is present, an advanced technique called Intra-Cytoplasmic Sperm Injection (ICSI) is used to inject a single healthy sperm straight into a mature egg.
Embryo Culture: The fertilized eggs are monitored carefully inside an incubator for 3 to 5 days until they develop into multi-celled blastocysts.
Embryo Transfer: A soft, flexible catheter is gently guided through the cervix to implant one or more select embryos directly into the uterus.
