Intrauterine insemination
- Intrauterine insemination is the process of extracting sperm either from husband or a sperm donor and depositing it in the uterine cavity.
- IUI is successful in women who have ovulatory cycles but have trouble conceiving. Other indications are oligospermia, cervical stenosis or unexplained infertility.[1]
- For IUI to be successful, the sperm count in the husband/donor must be >1 million.
- Since the released oocyte only survives for 12-24 hours, the process of insemination might be repeated 2-3 times over the period of 2-3 days.
- Some recommend controlled ovarian hyperstimulation with clomiphene for better results.[2]
In vitro fertilization and embryo transfer
- In vitro fertilization is indicated in patients with disease of the fallopian tube, unexplained infertility, endometriosis, failure of ovulation induction, mullerian agenesis.[3]
- The first step in IVF is down regulation of pituitary to prevent LH surge with GnRH agonists.
- Once Luteinizing hormone surge is prevented and adequate down regulation is achieved, controlled ovarian hyper stimulation is done with exogenous gonadotropins.
- Growth of follicles is measured with sonography. When 2 or more follicles of adequate size are seen, 5000-10,000 IU human chorionic gonadotropin is given intramuscularly, following which oocyte is retrieved.
- Retrieved oocyte is placed in culture and washed sperm is placed in the same culture media. The oocyte is then watched for signs of fertilization.
- The ova which is fertilized and at 6-8 blastomere stage is placed into the uterine cavity.
- Excess oocytes and embryos can be cryopreserved for the future.
Gamete intrafallopial transfer
- In this procedure, both thr sperm and unfertilized oocytes are transferred into the fallopian tubes.[4]
- This procedure requires that the woman have patent tubes and a normal uterine cavity.
- Ovarian hyperstimulation is done as in IVF and the collected oocytes along with sperm are placed laparoscopically into the distal end of the fallopian tube.
- This procedure is more expensive than IVF but has a better success rate.
Zygote intrafallopial transfer
- The fertilized oocyte is placed in the fallopian tube one day after in vitro fertilization.[5]
- Placement is done either laparoscopically or via uterine ostium.
- The risk of ectopic pregnancy is higher in this procedure compared to IVF.
Intracytoplasmic sperm injection
- This procedure is indicated in oligospermia, asthenospermia, congenital absence of vas deferens, unexplained infertility etc.[6]
- A single spermatid or spermatozoon is injected directly into the cytoplasm of an oocyte by puncturing the zona pellucida through an operating microscope.
- ICSI is found to be more effective than the other methods of micro manipulation such as subzonal implantation.
Others
- Embryo or oocyte donation can help in cases of premature ovarian failure, anovulation, old age, failed ART cycles.
- Women without a functional uterus may benefit from gestational surrogacy.[7]
- Oocyte cryopreservation can be done in women who are to undergo chemotherapy or radiotherapy.[8]
