Oxytocin is released in large amounts during orgasm, labor, and breastfeeding. Many call is the "love hormone". It is produced in the hypothalamus, a part of the brain. Females generally have higher levels than males.

Factors that can change your period with or without sex

Birth control

In a previous post, we discussed options for non-hormonal birth control that didn't affect your menstrual cycle. What we didn't talk about though were the hundreds of hormonal birth control women are using that DO change your cycle and period.

Hormonal imbalance

One of the most popular and disguisable is a hormonal imbalance. There are so many things affecting our hormones today, that it is virtually impossible to know if this this is your problem.

You may have a hormonal imbalance if you have experienced weight gain, sudden weight loss, fatigue, purple stretch marks, mood swings, etc. This is more commonly monitored by your health professional that looks at your health in a more holistic approach.

Trauma or stress

When your body experiences trauma whether emotional or physical such a surgery, a really hard breakup, or death--your body may cause you to skip or delay your period. This trauma brings stress to your body putting more stress on your hormones.

Extreme exercise or weight loss

Your body is adjusting to the sudden weight drop or sudden exercise. That's why some women may skip a period when they are getting in shape again.


Polycystic ovary syndrome (PCOS) is a hormonal disorder common among women of reproductive age. Women with PCOS may have irregular or prolonged menstrual periods or excess male hormone (androgen) levels. The ovaries may develop numerous small collections of fluid (follicles) and fail to regularly release eggs. PCOS (Polycystic ovary syndrome) is characterized by higher, sustained levels of certain hormones than normal.

Can your menstrual cycle change after being sexually inactive?

No sexual activity can have an adverse effect on periods. A late period or a completely missed period could have various reasons, such as stress, illness or poor health, a lack of food and very intense exercise and/or pregnancy medications that contain hormones or anything from the above list.

Can sex start or delay your period?

Sex alone has no effect on delaying periods or preventing them from occurring. Approximately 9% of menstruating women experience vaginal bleeding after sex that's unrelated to their period.
