(Yicai Global) Aug. 28 -- Men under the age of 35 make up nearly 90 percent of online contraceptive buyers in China, says a joint sales report from CBNData and e-commerce giant Alibaba Group Holding Ltd. [NYSE:BABA] released to mark yesterday's traditional Chinese Valentine's Day.

The most popular type of contraceptive in the country is condoms. Other means included in the report are birth control drugs, early pregnancy testing products, and ovulation testing kits.

Purchasers of contraceptive drugs, ovulation kits, and early pregnancy tests products are predominantly female.

People between the ages of 23 and 35 years old are the key customer group, of which with men aged 23 to 28 make up 39 percent.

Consumers exhibit cautiousness when purchasing contraceptives showing a degree of brand loyalty. The rate of repeat online purchasing of contraceptive drugs from January to May 2017 was nearly three times higher than the same period last year.

Traditional Chinese Valentine's Days falls on the seventh day of the seventh month in the Chinese lunar calendar.
