One or two pairs in a month or two a year or two ago is very rare. Now we can deliver more than 20 pairs of twins in one month.” Maternal Nurse Head Nurse, Maternal and Child Health Hospital, Nanjing Julie said.

Twins rise several times in 20 years

The statistics of newborn babies born in Nanjing Maternal and Child Health Hospital in recent years showed that in 1992, there were 57 pairs of twins and multiple births, and there were 4857 babies in the same year. In 1993, there were only 38 pairs of twins and multiple births.

By 2002, there were 77 twins and multiple births, and the total number of babies delivered was 7,017. In 2012, twins and multiple births increased to astonishing 363 pairs and 19123 babies were delivered.

The statistics of obstetrics of the Southern Medical University Affiliated Hospital of the Chinese Academy of Sciences shows that 46 pairs of twins were born between 2003 and 2007. By 2008 to 2012, the number of births of twins reached 168 pairs.

Ovulation drugs can be bought online

The reporter entered "promoting ovulation drugs" on a shopping website and jumped out of nearly 300 pieces of baby, but most of them were "Chinese medicine" or "secret recipes for ancestral ancestors."

An expert from the Nanjing Maternal and Child Health Hospital said an example. A friend of Nanjing citizen Ms. Li (a pseudonym) took an ovulation-promoting drug and was pregnant with a twin. Ms. Li followed the example of buying drugs online.

Unexpectedly, the twins were not pregnant, but she often experienced vomiting. The waist was twisted when she cleaned the room a few days ago.

The family sent him to the hospital for examination and discovered that Ms. Li had to remove one of the necrotic ovaries, and the other side also had obvious ovarian cysts.

Experts: Not recommending multiple pregnancy

The director of Ms. Ling Xiufeng of Nanjing City said that healthy people cannot accept IVF surgery and must be infertile to be eligible to apply.

According to the Ministry of Health's Assisted Reproductive Technology Regulations, patients under the age of 35 may transplant two embryos, and may receive 35 or more embryos for the second time, and up to 3 embryos may be transplanted. As a result, multiple pregnancies are significantly increased in assisted reproduction. About 30%.

Director Ling also reminded that multiple pregnancies will increase the rate of miscarriage among pregnant women by 10% over normal pregnancy, increase preterm birth rate by 20%, and have a fetal death rate of 135‰. In contrast, the proportion of malformed children with multiple births is also high. If you do not have a twin-family genetic gene, do not take risks for "twinning."
