Desire and Routine While Trying to Conceive

For many couples, the effort to conceive changes how they feel about sex. Intercourse that was once spontaneous and self-indulgent turns into a monthly task with a calendar attached, and a loss of interest can follow. The question surfaces regularly in sexual health columns, including letters from couples who found that frequent sex before trying for a pregnancy had given way to little desire.

From pleasure to commute

One columnist who addressed the question compared the change to cycling. A new rider enjoys the thrill, while the same person travelling to work every morning simply gets there. Sex that carries pressure, even pleasant pressure, can shift from play to responsibility in the same way. Sex therapists and counsellors describe this as a common pattern in couples who track their fertility closely.

What the fertility numbers show

Figures that appear widely in reproductive health literature indicate that, among healthy, fertile couples, most conceive within the first year of regular unprotected intercourse and a smaller share in the following year. Individual results vary with age and health, and the numbers are population averages.

How timing is determined

Fertility centres on ovulation. An egg survives roughly a day after release, while sperm can last for up to several days in the reproductive tract, so the fertile window spans only part of each cycle. People commonly follow it through three methods:

  • changes in cervical mucus, which becomes clear, slippery and stretchy near ovulation;
  • basal body temperature, which rises slightly afterward;
  • over-the-counter ovulation prediction kits that detect a hormone surge.

Clinical guidance on the frequency and timing of intercourse varies, and fertility specialists give individual assessments.

Separating fertile and non-fertile days

Some counsellors describe separating fertility-focused sex from other forms of closeness, such as flirtation, dates, massage and shared affection. The reasoning is that anticipation and variety can bring desire back.

Some people also turn to Traditional Chinese Medicine practitioners for questions about diet and herbs. Evidence for those approaches is mixed, and medical bodies in Canada generally direct couples with concerns about fertility to physicians.

Wider context

Researchers note that stress, fatigue and the demands of new parenthood can lower libido independently of conception efforts. The topic overlaps with infertility, where the emotional load of scheduled sex is often greater.
