Scheduled Coitus

Coito Programado

Scheduled Coitus is a treatment consisting of low complexity in achieving ovulation induction through drugs, monitoring with ultrasound. During treatment, ultrasound scans are performed, usually every two or three days to follow the growth of the follicles. When the follicles reach optimal size, ie, the ovulatory period, the couple is advised to have sex more often. Thus, treatment can predict which day in the cycle the woman will have a higher chance of getting pregnant.

The treatment basically starts in the second or third day of the cycle, when the woman is still menstruating. In that moment the first transvaginal ultrasound is performed. The patient should not be worried about the discomfort of menstrual blood, because doctors are used to performing it at this stage. This initial stage is important because if the test diagnoses ovarian cyst resulting from the prior menstrual cycle, and the uterus contains polyps, fibroids or excessive endometrial tissue, which would change the rate of success.

In this first ultrasound, the ovaries must have small cysts measuring up to 6 mm, called primordial follicles. Inside them there are oocytes and they leave at the time of ovulation. Depending on the result of this first test, the ovulatory control may be initiated to determine the likely day of ovulation.

During the treatment, the follicle(s) and the endometrium should grow progressively, which is scanned through more ultrasound exams, more precisely every two or three days. When the follicle(s) reach the appropriate size it is applied a medication called hCG, which promotes final maturation of the oocyte and its ovary exit. After this stage, the oocyte is released and captured by the tubes, and within them fertilized by sperm derived from normal sexual relations.

This treatment makes it possible to predict or plan the best day for the couple to have sex, hence the name scheduled intercourse, sex or dating.

The chances of a couple becoming pregnant through scheduled intercourse is around 10 to 12% and varies due to several factors such as the age of the woman.
