Conception is a complex physiological process. Basic conditions must be met for pregnancy, and all of them are indispensable.
(1) The testicles can produce a sufficient number of sperm with normal shape and motility, and the semen can be transported smoothly.
(2) The ovaries can produce normal mature egg cells and secrete normal amounts of hormones, and the fallopian tubes are unobstructed.
(3) During a certain period of time before and after the woman’s ovulation period, the couple should have a normal and harmonious sexual life. The structure and function of the reproductive organs of both men and women must be normal to ensure that sperm enters the female reproductive tract and combines with egg cells.
(4) A good uterus and normal endometrium must be suitable for the implantation and continued development of fertilized eggs.
Problems in any of the above conditions and links can cause infertility and infertility.
Basic conditions for male fertility
The basic conditions for male fertility must meet the following points:
(1) Have normal The hypothalamus, pituitary gland, testicles and their regulating balance release hormones, gonadotropins and testosterone.
(2) There are normal sperm maturation, storage and output channels, including epididymis, vas deferens, ejaculatory duct and urethra.
(3) External genitalia with normal blood supply and innervation, including penis and scrotum.
(4) Have normal accessory reproductive glands, including seminal vesicles, prostate, bulbourethral glands and urethral glands. The secretions of these accessory glands and sperm constitute semen.
Therefore, the male reproductive process is completed through a series of physiological activities such as spermatogenesis, sperm maturation, and sperm ejaculation under the regulatory control of the endocrine glands of the central nervous system, hypothalamus, pituitary gland, testes, and gonad axis. , abnormalities in any one of them can lead to male infertility.
Essential conditions for female conception
The following four points are necessary for female conception. If one of the conditions is abnormal, it can cause infertility.
(1) The hypothalamus-pituitary-ovary are healthy and functioning normally. Under its control, there is normal ovulation and sound luteal function.
(2) The vaginal opening, vagina, cervix, uterine cavity, and fallopian tubes are healthy, sound, and all unobstructed. Have a normal and harmonious sex life. Normally mature sperm can pass through the female reproductive tract to the ampulla of the fallopian tube.
(3) The fallopian tube has good function and can pick up eggs and make them enter the fallopian tube.The ampulla meets the sperm for fertilization, and the fertilized egg can migrate to the uterine cavity.
(4) The endometrium has sufficient and synchronous changes in the secretory phase, and the fertilized egg can implant in the uterine cavity.
In addition, women should be in good health and in a happy and optimistic mood during pregnancy.
