Now, fertility experts pick ‘best’ sperm

Fertility treatment just got better with city doctors handpicking the best sperm to be fused with the egg.

Experts have improvised on intracytoplasmic sperm injection - a method in which a sperm is physically injected into an egg - to come up with the new technique of intracytoplasmic morphologically selected sperm injection (IMSI). The procedure involves use of powerful microscopes to look at and select the healthiest-looking sperm to improve the success rate of conception.

After using the new technique on more than 900 couples, Chennai-based Prashanth Fertility Research Centre said it has boosted pregnancy rate of artificial insemination by 10%. "Because we choose the best of sperms, the incidence of abortion has decreased," said fertility expert Dr Geetha Haripriya.

On Wednesday, doctors at Prashanth Hospitals announced that a couple who had undergone IMSI had twin babies last week. The technique, they said, gives new hope for couple who had failed conventional fertility treatment.

Men with fertility problems do not produce normal, healthy sperms that are capable of swift movement towards the egg. In such cases, ICSI, which stands for intracytoplasmic sperm injection, is the only way to produce an embryo. "But even such procedures fail because sperm we select may not be completely healthy," said Dr Haripriya.

In IMSI, after the microscope magnifies sperm 7,200 times, a computerized semen analysis picks up the best sperm to be fused with the most fertile eggs. Dr Haripriya feels IMSI is superior as it makes the selection process more stringent. After two to five days, the fused egg-sperm is injected into the uterus.

Fertility expert Dr Priya Selvaraj said she did not see a major difference in success rates between the two procedures and would wait before applying IMSI on all couples. But Dr Geetha Haripriya says the success her clinic has seen encourages her to do so with all couples who have complaints of male infertility. Nearly 65% of infertile couple has male infertility. Patients opting for IMSI will have to pay 15,000 more than ICSI (which costs 1.5 lak
