American reality television star Kim Kardashian is allegedly taking drastic steps to get pregnant again.

According to Hollywood Life, the 34-year-old Keeping Up With The Kardashians star even convinced the 37-year-old rapper not to wear leather pants, which increases the chances of "killing and damaging sperms".

"Kim is not pregnant yet. She and Kanye are doing everything humanly possible to make it happen, but so far they have had no luck," a source told the website.

"Kim and Kanye have stopped drinking alcohol and she makes sure they both get enough zinc, folic acid, calcium, and vitamins C and D. Also, Kim has outlawed hot tubs, saunas, hot baths, and really hot leather pants on Kanye since heat kills sperm," the insider added.

Kardashian, who has 21-month-old daughter North West with Kanye, has revealed that she is desperately trying to get pregnant.

In the season 10 premiere of Keeping Up With The Kardashians, Kim told sisters, Khloe Kardashian and Kendall Jenner that she and Kanye are "having sex 500 times a day".

"The doctors said he thinks I'm having sex too much," Kim told E! News. "He said one time is more powerful...so we've tried everything."

"I've done everything so perfect to try and get pregnant. There's a list of things you shouldn't be doing and I was perfect for eight to 10 months and now I don't understand.

"I'm going to do everything that I want to do and that includes going platinum. Hopefully I will get pregnant doing all the wrong things. I'm totally changing my tactics."

"Literally teenagers on meth get pregnant in two seconds. It's crazy. When you don't want to be pregnant, it happens," Kim joked.
