Intracytoplasmic sperm injection (ICSI): This procedure involves direct injection of a single sperm of the male partner into the eggs of the female for fertilization. Just like IVF procedure, in ICSI, the sperm and egg are collected from both the partners. The only difference is the fertilization process as in IVF the sperms and egg are mixed naturally, and in ICSI the sperms are injected into the egg using a needle.
Ovary stimulation. For eight to 14 days near the beginning of your menstrual cycle, you take a gonadotropin, a type of fertility drug that stimulates your ovaries to develop multiple mature eggs for fertilization (instead of just one). You also need to take a synthetic hormone like leuprolide or cetrorelix to keep your body from releasing the eggs too early.
Luteal support is the administration of medication, generally progesterone, progestins, hCG, or GnRH agonists, and often accompanied by estradiol, to increase the success rate of implantation and early embryogenesis, thereby complementing and/or supporting the function of the corpus luteum. A Cochrane review found that hCG or progesterone given during the luteal phase may be associated with higher rates of live birth or ongoing pregnancy, but that the evidence is not conclusive. Co-treatment with GnRH agonists appears to improve outcomes, by a live birth rate RD of +16% (95% confidence interval +10 to +22%). On the other hand, growth hormone or aspirin as adjunctive medication in IVF have no evidence of overall benefit.
