In this article, we will discuss the factors that can affect fertility in women. If you are looking for Singapore Fertility, you can visit our clinic, or you can visit our website first to get more information.

 

1. Age
Many women wait until their 30s and 40s to have children. About one-third of couples where women older than 35 years have fertility problems.1 For women under 30, pregnancy rates reach 70-75% But drop to 60% in women aged 30-35 years, and 50% in women aged over 36 years. Another study of couples experiencing difficulty in achieving pregnancy has a 10% infertility rate in women under 30, 15% in women aged 30-35 years, 30% in women ages 35-40, and 60% in women aged at Over 40 years.

The results showed that the number of aneuploid oocytes increased with age. This increase results from the disturbance of the mechanism of regulating the formation and function of spindle yarn during meiosis. In addition to entering the age of 30 years, women are more susceptible to various diseases such as endometriosis that can affect fertility. Exposure to environmental chemicals and work can also reduce fertility in older women.

2. Cigarettes
Smoking affects both male and female fertility. The prevalence of infertility is higher and the time for conception is longer in women who smoke or even in those who are passive smokers. Toxins in cigarette smoke can accelerate follicle depletion and increase genetic mutations in gametes and embryos. In addition, cigarettes also endanger the motility of the fallopian and the implantation effects of the embryo. This is mainly due to the effects of cigarettes that reduce blood flow to the reproductive organs. Cigarettes also compromise the quality of the ovum, reduce the ability of eggs to be fertilised and increase the likelihood of miscarriage. A decrease of up to 22% is seen in the fertility of women smokers. Men who smoke have lower sperm count and motility and increase abnormalities of sperm form and function.

3. Sports
Weight training can alter the function of menstruation and interfere with female fertility temporarily. The frequency of amenorrhea or oligomenorrhea in women who participated in various activities around 2-51%, while in sedentary women about 2-5%. The prospective study showed that women with normal menstrual cycles before, 87% cycles turned out to be abnormal when in a strenuous exercise program. Hormone abnormalities also occur, including discharge disorders and gonadotropin levels, decreased oestrogen levels, inadequate corpus luteum, and complete anovulation. Abnormalities arise most often when exercise is most intense or when exercise becomes harder. The mechanism of menstrual irregularities associated with severe exercise is unknown. It is estimated that exercise causes changes in prolactin and endorphins that affect fertility.
